Hi I have a 1990 aclaim and the barke lights and turn signals stopped working, fuses are fine. Any Ideas where to start?

Well the brake light and turn signal circuits are on two different fuses, but they both go thru the turn signal switch.
So I would start by checking for power in and out of the turn signal switch for each circuit.

check the signal fuse

yes they run off of seperate fuse in fuse box. as always check the bulbs first.

It is entirely possible that you have more than one issue.Perhaps you could fill me in as to whether the tail lamp issue and the turn signal issue occurred at the same time. For now a cheap remedy would be to replace the turn signal flasher as that is likely for the turn signals not remaining on. Let me know if this works....after this further diagnostics will be required.

The issue is most likely the Brake pedal switch because the barke and turn signals use the same wires from the combination/turn siganl switch to the tail lights. I might just need an adjustment.

rear brakelight bulbs

Hi..my name is Keith...and if your bulbs work with the hazard/emergency ..then the bulbs are fine..and the turn signal and hazard lights should share the same fuse.my best guess is the turn signal switch is bad..and its mounted inside of your steering collum..i hope this helps

I had the same problem and the flasher is not located in the fuse box because it is not a normal flasher. the cougar has an electronic flasher unit that is located on the left side of the center console. the best and cheapest place to order a new one is amazon.com. they run about $30-$40

sounds like you have a faulty turn signal switch. in your car the same lever can control lots of things, turn signals, bright headlights, flash to pass, not sure that's all, maybe the wipers too. so gm calls that thing a multifunction switch. can you change it yourself? maybe. will it be easy? depends on what else you have done. you have to take the steering wheel apart to get to it. i think your car is new enough to have airbags, so you have to deal with that. if you are still interested in doing it yourself i can give you a play by play, just trying to let you know you do run the risk of deploying the airbag so you need to decide if you think it's worth it.

Probably because it blows immediately because the short is now a dead short. The hot wire is completely against the ground not just rubbing. Has the car been hit in the back at any time? Look underneath and see if any wires are hanging down.around the tail light area. Your looking for a wire that is rubbing against metal . Could be inside the trunk behind the covers .
