    Yes. All the bulbs, fuses, and flasher relays for hazards and turn signals have been replaced.

  • misscole77 Jul 01, 2009

    No nothing at all happens when I turn the signals on. No lights, no dash indicators, nothing.

  • Christopher Keene May 11, 2010

    are the lights coming on but not flashing? are the indicators in the dash coming on? does the turn signal arm return to center after turning steering wheel?if the answer to these ?'s is yes you may have a ground fault and possibly need to apply alternative grounding points to lights. lemmee kno chris

Yop may have a very common problem unique to that year car.
I have two definite fixes for you:
Open the trunk. Look at the wiring harness that is hooked onto the driver side arm that holds the trunk lid to the body. Untape the wiring harness from the edge of the trunk lid back towards the driver rear seat. You are most likely going to find a broken wire or two, prob a green with a red tracer. The repeated action of lifting/closing the trunklid seems to break the brake/tail power wires. If the wiring harness is perfect, no breaks, AND you have a rear spoiler, remove the trunk interior trim that faces the driver side 1/4 panel. Hidden behind a brace will be a small box. This is the brake lamp sensor. If it has failed, you may need to replace this box. Either fix should resolve your issue.

Look in the fuse panel and the turn signal flasher is the big round most likely yellow or silver in the corner of fuse panel. The emergency flasher is in the back side of fuse panel right directly behind the turn signal flasher.
Remove the emergency flasher and install it in place of the turn signal flasher and see if this corrects the problem and if so get a new flasher. If this does not correct it problem will most likely be the multi-function switch.

If you haven't done so already, change both flashers that are mounted in the fuse box, the one for turn signals and the one for the 4 ways.
You might have a bad turn signal switch.

How do i fix my blinkers on my 1971 f100 ford ?


There is a flasher unit for the turn signals, separate from the hazard flasher, that is under the dash. If the fuse for the turns is good, and you already know the bulbs are good since the hazards work, then you may have a bad turn signal switch.
When you use the turn switch, do the bulbs come on and stay on, or nothing? If they come on and don't blink, then it's probably a bad turn flasher unit. If they don't come on at all, suspect a bad turn signal switch. But first check the fuses, then pull off the connector to the turn switch and see if you have one hot wire there, with key on. That one hot wire will be from the fuse.

Blinkers dont work. flashers work


Most GM the blinkers and flashers have seperate relays. But if see your flashers work you know the bulbs are good. So there is one thing out of the way.

The turn signal relay should be a two prong relay on the interior fuse panel. The hazard relay would be one with three. The hazard relay may be on a "convienience" center which is usually tucked way up under the dash.

How to fix turn signal on 86 Chevy Astro Van


you don`t say but do the lights work either on the front/back on both sides.if not then it may be a fuse that needs replacing or need a bulb replacement.if the lights work but don`t flash then it sounds like a signal flasher problem.the flasher is located in the fuse panel under the dash on the drivers side.if the hazard flashers work then turn them on to find the hazard flasher by the fuse panel then you will know what the signal flasher looks like and change the signal flasher.make sure you change the one for the signals and not the hazard one.if the hazards work then i would say the signal switch is good as the hazards work through the same switch.

Blinkers dont work but 4 ways work.


Check your turn signal fuse first, if the fuse is found good, replace the turn signal flasher.
I am assuming when you state the blinkers are not working that both the front and rear turn signals are not lighting at all.
Good luck.

Hazards and blinkers not working


There are separate fuses for the turn signals and blinkers, but you should check both of them just to see if they're good.

You may have a burnt out turn signal bulb as well. I know that this sounds like an obvious answer, but a single bulb can sometimes disable the entire system because of the way that some flashers operate.

You could also have a defective turn signal/hazard light flasher. This is located under the dash board on the driver's side between the steering column and the door. You have to remove the sound insulation/kick panel (the cover on the bottom of the dash board) to reach the flasher (it is easy to remove - I don't think you even need tools).

Blinkers stopped working


Your F--150 has 2 flashers, emergency and turn signal. Both are mounted on the fuse block under the dash. The turn signal flasher is mounted on the front of the fuse panel, the emergency flasher is mounted on the rear of the fuse panel. so replace the turn signal flasher should solve the problem. Let me know how it goes.

Blinkers not working


Did you check the bulbs? If one bulb is burned out, the blinkers won't word on that side. You could have one bulb burned out on each side. Start the car, put left signal on. Check front and back lights. Is one light on but not blinking? If that's the case, the light that's not on at all is burned out and has broken the circuit so the good light stays on and won't blink. Check the other side. You also have a 'flasher' , actually 2. One for emergency flashers, one for the turn signals. It could be that the turn signal flasher is shot. You just have to unplug it to remove. It's probably located near the fuses. good luck countrycurt0
