The turn signals do not flash or they may flash in only one position or one side may remain on constantly with the switch in the off position.

The turn signals use a flasher unit that acts as a repetitive circuit breaker. This unit makes then breaks the electrical circuit that turns on the turn signal bulbs. The cycle will continue as long as the directional switch is turned on. This unit relies on heat build up caused by electrical current flow to determine when to break the circuit. When the switch is initially turned on, electrical current flows through the flasher unit to the bulbs. When this occurs, heat builds up in the flasher unit. When the heat reaches a predetermined temperature, a metal strip within the unit stretches due to the heat and breaks the electrical circuit turning the bulbs off. With the bulbs disconnected from the circuit, the flasher unit cools off. Once it has cooled, the metal strip re-contracts and re-closes the electrical circuit turning the bulbs back on. The usual cause of inoperative turn signals is a defective bulb or flasher unit.

Prior to performing extensive diagnosis, check the vehicles fuses to ensure they are not blown. Some vehicles utilize two fuse boxes, one in the passenger compartment and another under the hood. Consult your owner’s manual for fuse box locations and fuse ratings. If the directionals only flash in one position and are off constantly in the other direction, the usual cause is a burnt-out bulb. When a bulb blows, the current flow in that side of the circuit will be reduced. The reduction in current flow prevents the flasher unit from reaching the needed temperature to switch the bulbs off. Turn the directionals in the position where they are inoperative and perform a visual inspection of the exterior bulbs. Replace any bulbs that are not lit. The flasher unit is used to switch the current on and off for both right and left directionals. If the turn signals are inoperative in both directions, a defective flasher unit or blown fuse is the usual cause. On most vehicles the flasher unit is located on the front or on the back side of the fuse box located in the passenger compartment. Some vehicles use a solid state flasher module that contains transistors and diodes. On these vehicles, you should consult a vehicle specific service manual for proper diagnosis.

You should always use a replacement bulb of the same part number as the one being replaced. Your owner’s manual will indicate the correct bulbs for each location on the vehicle. Using the incorrect bulb can create too slow or rapid turn signal operation. Manufacturers often use grease to repel water from the bulb sockets. Do not remove this grease from the bulb socket when replacing defective bulbs.

    What if the bulb is good the switch was replaced and still no signal lights. What else could be the problem?

        I have a 1995 ford f-150 have no brake lights in rear of truck but do have brake light on back of cab of truck, no turn signal lights and no emergency flashing lights, replaced turn signal switch and brake bulbs and fuses and turn signal fuses and do have tail lights, PLEASE help me with out?!!

        • Da-Sarge says:

          With the F150 check the two electrical connectors uner the bed of the truck back by the rear bumper one is round and the other is a square shape these like to carrode rendering the rear lights inoperable also tge tail light sockets can be unplugged from the harness (careful with the clips on eather side of the sockets they like to brake) the tail lights on the 90s and early 2000s (up to current for f250 and higher) they tend to get water in the lights that kills sockets these are the usual causes of the problems if you loose all rear lights check the harness by the chasis in the front drivers side wheel well for chafeing (can also cause rear light loss) very commen on the 1996-2003 F150 all cab and trim types and bed types these are the commin areas to look for failures hope this helps you out

      • Rob says:

        Larry, did you find a solution? My 97 F250 does this. Slow, then fast blinking, then stalls out for a few second, and right back to slow and fast.

    • Alex says:

      Hey guys my issue has me stumped. My blinkers don’t work nor do my break lights, unless the hazard switch is on. And even then they don’t flash the just stay lit when switch is turned on either side. I changed fuse checked grounds and changed relay. Found out the relay turns on but won’t turn off even if I don’t have keys in ignition. Now my radio won’t work and my interior lights don’t work all share a pink wire. I’m confused. HELP PLEASE

  5. Tommy says:

    Yes you are exactly right! Thank you so much! I changed the flasher and she works fine! $4.00 Thanks to your advice probably saved me up to $400 on mechanics which I’ve seen that many do blow smoke to steal your money. I was thinking I’d have to get someone to pull my steering wheel and change out the tumbler switches! God bless you!

    I replaced the flasher on a ford f 150 1998 but still dont work my turn signal stilk dont work

  7. John S says:

    I have a 1995 GMC 1500 4×4. My rear blinkers, brake lights and 4 way flashers do not work, But they all work in the front. My rear running lights work.
    I haves tested all the bulbs they are good, also tested the rear ground wire it is good. Could the problem be my relay under the hood? I am led to believe it controls both the blinkers and the brake lights?

  8. brian v says:

    I have a 76 cheyenne, and i have been having the same problem. My turn signals dont work. But brake light and hazards do i checked the fuses, new flasher, and replaced the turn signal switch but still nothing.

      I have a 1947 Ford car and installed a after market turn signal switch. The blinkers work great until I turn the headlights on then only the front blinkers work and the rear lights light up but do not blink. Also I have no brake lights. Checked all the fuses and grounds and they look fine. What should I be looking for to fix this problem?

  11. Steve says:

    Thanks just got new headlights the blinkers in front didn’t work I got new bulbs with them. Never expected them to be bad but thanks to you I rechecked bulbs and they were bad

  12. al says:

    hello, I just rewired a trailer correctly and the lights function properly. however, the right signal flashes a little fast (trailer connected or not)and the bulbs are flashing on the trailer,but the right blinker seems to to bleed a little into the left light on the trailer only, but not vice-versa. Now that’s strange. What do you think. Thank you.

  13. Gregg says:

    I have a problem I’ve never seen before or heard of. When I put either left or right blinker on ALL lights blink like my hazards are flashing with the turn signal.

  14. tracey-lynn kennedy says:

    just wondering my hazards light works but right and left single doesnt changed fuse and nothing on a 2000 pontiac sunfire thank -you

  15. Matt says:

    For some reason my blinker flashes with the switch in the off position UNTIL I turn my headlights on, that’s the only time it will stop blinking. I do have a blown headlight bulb on the left side, which is also the blinker that is malfunctioning. I’m not sure if the headlight being out is relevant or not seeing as though my blinkers and headlights have separate housings. Anyone offer any advice?

  16. den says:

    There’s a wire going down too your brakes make sure it’s pulled in all the same had the same problem

  17. den says:

    There’s like a relay down there its what makes the clicking noise when you turn on your signal! !!

  18. nandu says:

  19. Stan says:

    I have a 2000 Buick La saber. The left turn signals is acting like it is on double time. The Left rear turn signal lightbulb was out so I replaced it. It still doing The left turn signal double time, with no light on the left rear signal. Next I replace the 15 amp in the fuse box. Still not working right.
    What is your thinking to resolve this problem?

    my left turn will not stop bilking

  22. peter conti says:

    I have a different problem on my 98 max. My passenger side front blinker is not working while the rear one is working (The driver side blinkers are fine). I checked the bulb and even replaced it with new one, it’s still not working. This is actually the second time is happening. The first time, I gave up and suddenly (I think after I hit a bump) it started working again. This time, my wife hit another car (no damage to the cars), and it quits working.

    I’ve got different opinion about the cause of the problem. It’s not the bulb. It’s not the relay because the rear one is working. It’s probably the ground connection.

    Anyone experienced the same problem?

  23. Hector Lopez says:

    I have an ’06 Pontiac Grand Prix (Base Sedan), all my blinkers are working, tail lights, headlights everything. But the rear passenger side blinker is not blinking. The bulbs on but it won’t blink. Have 1 Hazard/Signal fuse in the inside compartment (20w) and it’s fine. I’m confused here.

  38. Peter Wainwright says:

    I have a 1999 plymouth grand Voyager with intermittent signal problems.

    Right turn signal works all the time
    Emergency Flashers all work and work all the time when flasher button depressed.

    All bulbs are good.

    Left turn signal may work randomly for a few miles and then suddenly stop. Sometimes it will not come back for days and will not stay working for more than a few miles on any day.

    Already replaced turn signal lever switch (multifunction switch) and it did not make an improvement.

    someone told me it could be ignition switch related. Another person says flasher relay unit.

    Any suggestions?

  44. Bridget says:

    I have a 96 dodge neon. My blinkers stopped working after the car sat for 7 months. It did get a heater core replaced. When I turn on my blinkers the passenger front doesn’t turn on at all. But they blink really fast. I checked all bulbs they are good. I replaced the bulbs of the ones that are not working and they still don’t turn on. Then when I turn on my headlights or flashers on the flashers won’t blink and none of the blinkers work but in the dash the indicator the left side only stays on. What can this be?

    • Al says:

      You should check to confirm that the right bulbs are installed. Sometimes when people replace bulbs they use the wrong ones. The 161, 168, 194 and 921 are problems; the bases are all the same but they are different wattages, and the lighting circuits are designed such that they only work as designed when you install the correct bulbs. SO – if you can’t read the writing on the bulbs any more you’ll need to replace them with bulbs of the correct type. The owners manual for your car will say. If you don’t have an owners manual call a couple junkyards and ask, they often have them in from cars people are junking; you also can get one from a dealer, they are not very expensive, and sometimes you can do a web search using google or some such and find them to be downloaded on line for free.

      Good luck

    Flasher replacement needed?

  48. Woody says:

    I have a ’93 GMC Sierra and my rear break lights and blinker will work every once in a while (very rarely). The left side lights will work just fine every time, not the same with the right side though. The right side lights very seldom work. The front are okay.

  49. David says:

    I have a 03 gmc sierra. both turn signals do not work. Checked all the fuses and they are all good.

Need help for a new angle for troubleshooting.

    Hi! i have a chevrolet optra 2007 and the hazard lights won’t work unless the turn signal switch is on (either left or right) together with the hazard button. Turn signals work perfectly fine. thank you.

  51. Mir says:

    Hi! So I put my left blinker on to turn into my driveway today, and it didn’t turn off. Even when I manually put the lever in the off position, it stays blinking. But the weird thing is, is that it will turn off when its in the right position. The right blinker also doesn’t work in the right position, so I have no right blinker. To make it simpler, here’s how it is=

    Left position=left blinker
    off position=left blinker
    right position=no blinker

    I drive a Saab 9-3 convertible. Any suggestions?

    Hi – 1991 Ford Ranger Supercab – Rear Stop/Turnlights flash together whenever ignition is on. Hazard lights work normally, brake lights and running lights work OK. When turning left, front signal light and left rear turn light OK; when turning right, fron turn lights and BOTH rear lights flash. Checked front ground on drivers’s side engine compart apron, rebuilt rear wiring harness (PO had cut out the plug and licence light subharness, and left some of the subdived wires dangling, but this did not help. Checked all bulbs and rear sockets.

    Phantom rear flashing goes away when I speed up but dash volatge indicator is always high side of normal. Low volatge problem?

  63. Sam says:

    Hey, I have a 1989 Eddie Bauer bronco 2. I just noticed today my turn signals both stopped working, as well as my reverse lights. My hazards worked fine so I swapped the relay of the hazards into the turn signals. The turn signals both worked, and my hazards no longer worked, so the other relay was blown. Then my turn signals stopped working minutes later. And I swapped the relay back and neither work so both the relays are blown. Does this mean I have a short somewhere? If so how do I go about locating and fixing this? I already changed the 15amp fuse for my turn signals btw, that was not the problem.

  64. Joey says:

    My turn signal went out and i rode it out for a while. Then my break lights stopped working also. Unfortunately my brother in law wrecked his and we have the same model. So I took his multipurpose switch and put it on my truck now I’ve got brakes but they disengage when I turn the blinker. Sorry 2000 Ford 150

  74. TedJackson says:

    My daughter has a 2010 Nissan Sentra. The original bulb is a 3057 and a retailer sold her 3057A, saying it is the replacement bulb.. The new bulb works for a few seconds of flashing and then stops. It doesn’t start again until the bulb is removed from the socket and reinserted. Why?

  75. Becca says:

    My driver side flasher does not work. The dash does not light up or outside blinker light. The right side blinker works no problem. I tried to change the bulb but still nothing. Do I need a special flasher bulb or could it be a fuse or wiring? It is very dirty where the light housing is. This is a 2003 dodge Durango. Thanks!

  76. aldo says:

    1998 Mitsubishi mirage. Turn signals stopped working, both sides. 10A fuse (in passenger compartment) looked ok, but went ahead and replaced. Swapped turn signal relay/flasher (in passenger compartment) with hazard relay/flasher. Hazard lights still functioned. Turn signals still did not function. Replaced turn signal switch assembly on column. Turn signals still do not function. Are there any other fuses or relays for the turn signals under the hood? There is a rectangular fuse/relay box under the hood. However, the information on top of the box does not clearly show what each of them services.

  77. Mike Etgen says:

    In my 1986 Mazda B2000, the front signal and parking lights share the same bulb. The bulbs work when lights are on. LF turn signal does not work but LR does, at correct frequency. When R turn signal is on, the flasher in the dash blinks rapidly, the RR bulb flashes, but the RF does not operate at all. I’ve gone through and checked/corrected corrosion where found in sockets. I have not been able to remove the flasher to substitute another. Other ideas?

  78. Ben Johnson says:

    I have a 1971 Plymouth Fury III. My hazards work fine, but turn signals (both sides) stopped working the other day. I also recently went over a speed bump, and the headlights went out. When I turn the brights on, the lowbeams still work fine. Very confused. I changed all the fuses out, so that’s not it. Any help would be much appreciated! Thanks, Ben.

    I have a 1997 Chevy Silverado with LED turn signals instead of bulbs, so what do I do? All of the lights blink when hazard switch is on, so what is the problem? I am using a LED relay switch and I do not know what else to do! My 3rd brake light does not receive power sometimes or it will not turn off when all switched are turned off and when the key is off. I have been looking online for solutions for weeks and have not been able to find any useful help to fix my issues. I have checked and double checked the fuse boxes both under the hood and in the fuse box on the drivers side. I am trying not to spend a lot of money to fix these problems. Any solutions??

  89. Deezy says:

    HI, okay, so i have a 97 jimmy, and all 3 brake lights dont work.. my signals work, but they are screwed up.. so when i put my signal on to the right, my turn signal plus reverse light, and my hazard light light up (and the left side blinks as well) but when i turn my left signal on, it works normal.. so i have checked my fuses and the only one im missing is my STOP/HAZ fuse.. (problem is, 1, i still have no brake lights, and 2, something is wrong with my brakes all together.!) so i took that back out… i checked my wires behind the truck (at the trailer connector) and i found someone who wired the truck put my 2 Aux Stoplamp wires and wired it with the white heavy gage wire, which is my ground. and of course they were all melted together….. so ive recently seperated them and grounded my heavy gage wire… and just when i thought i could fix this problem, well i still have no brake lights……

    I am NOT a mechanic, but I am trying to learn everything i can about vehicles… so if someone can help explain to me what i am to do… i am willing to try… ive been on this truck for 2 days now…. lol plz help!

  93. Stuart Ross says:

    Right turn signal malfunction. Going twice as fast as normal, front illuminates, rear does not. Is this a fuse issue or burnt out bulb issue?

  94. Marcus says:

    The problem I am having it’s not with the turn signals working or not working. The problem is that when I turn the lights on whether it be full headlights or just running lights nine times out of ten the passenger bulbs for the turn signal are lit with a steady light as if I was holding the turn signal in the on position and then while driving down the road it will flicker on and off at no particular rhythm. It occasionally stops and other times it just flickers away. Fuses are good and so are bulbs.

  95. Shane says:

    Does any one know how to fix a problem if the turn signal does not turn off automatically after completing the turn?

  96. Tina says:

    I have a 2000 Ford F150 XLT it has 4.6 triton. I recently had a water hose blow off the radiator while driving down the road. Before this happened I had no problems at all with my electrical system. I fixed the issue with the hose and got back on the road. I noticed that later I tried to use my cruise control and it wouldn’t work. the next day I lost all blinkers and my emergency flashers as well and brake lights. The head lights and running lights work just fine. I found a fuse that had blown that operates all this but if I try to use any blinkers or brakes the fuse blows again every time. Now if I unplug the brake light switch everything else stays working with no issues. What is making this happen this is my work truck and need it every day?
