its probably a bad multi function switch
Turn signals just quit working- have replaced flasher- checked all bulbs and fuses, checked all obvious wires, cleaned grounds, replaced the turn signal switch (that was an adventure). At a loss- any help out there? Hazards work fine- all other lights work fine- turn signals dead
Perhaps problem in the steering column switch?
I have the exact same problem as u in my 87 firebird i dont know what to do
Defective flasher relay.
Could be the flasher unit.
Check the flasher for the turn signals which is under the dash on the left side of the steering column . It is different from the emergency flasher.
The directional signals and the emergency flasher each have their own flasher unit. They are the same type of flasher and should be beside each other under the dash.
I checked the fuses first, they were not blown. Next I replaced the turn signal relay that is located on the back side of the fuse panel inside the car. That was the problem.
Have you checked the flasher fuse. Its in the fuse box by the brake pedal. Its the larger round one, you might have knocked it out of place or it has to be replaced. Check it out. When the flasher is on, you can hear a ticking coming from it.
Blown fuse or bad flasher unit. Often, cars use different flasher for the turn signals and the flasher, so it is possible for the hazards to work and not the turn signals.
check the ground on your tailights R.W: Have you checked the turn signal switch? That may have to be replaced.
If you replaced the flasher on your 1999 Mercury Cougar and your turn signals are still not working, you should check the turn signal fuse. This fuse is located under the dashboard on the driver's side of the vehicle to the left of the steering column.
