check the turn signal relay in the steering colum, just before the turn signal switch the plastic receptors may be broke.
The only thing that will work with key OFF is the brake lights,head lights and emergency flashers. Dome light will also work.
It's the turn signal switch which is the culprit.
The turn signal switch in the colum could be bad COULD B the TurnSignal switch OR the Flasher 4 the Emergency FLASHERS (because there is 2(two) Flashers & the Brake light Switch on the Brake pedal could B Bad.(turnsignals Have there OWN Flasher) the emergency flasher switch has 3 electrical contacts.sometimes they overheat and melt into the red flasher switch deforming the whole switch.unfortunatly the whole blinker and flasher needs to be replaced.
TRY TURNING THE EMERGENCY FLASHERS ON AND OFF A COUPLE TIMES THEN CHECK YOUR BRAKE LIGHTS. WORKED FOR ME.
Start by checkin all fuses and then go through all your wirein to rear lights and the check build recepticals for wear and corosion..
False
It depends on the car. Some cars require that you turn on the turn signals to make the 4-way flasher work. If that's the case with your vehicle, make sure the emergency flashers aren't on. Otherwise, it's probably a problem with the turn signal switch.
You may want to check the brake lights.Everything runs through the multi-function switch.(the turn signal switch)
On the 1979 B200 Sportsman V8 if the brake pedal makes all signal lights come on and hazards and flashers do not work on their own, it could be the flasher, but the culprit could also be a burned out bulb or a short in the wiring.
Because the brake lights are the priority circuit.
First thing I'd check would be the fuse for the stop lights. If it is okay the next thing I'd check would be the stoplight switch located under the dash where the brake pedal is suspended.
You probably need a new turn signal switch. I have a '96 Monte Carlo and I had to replace the turn signal switch to get the brake lights to work. Thankfully I had a brother who knew how to take off the steering column and replace. Hopes this helps!!!
