try replacing the dimmer switch they sometimes go bad and do not allow voltage to the lights
Even after replacing the switch it needs to be aligned with the shifter. Put the car in reverse and then have someone watch the lights as you loosen the switch and then rotate it slightly forward or backwards. once the lights come on, secure it in position.
no. try replacing the headlight switch... eBay
the switch on brake pedal is faulty and needs replacing
About the only thing they have in common is the headlight switch. Have it checked out.
I would start with replacing the head light switch
If your brakes lights are not working and all of your other lights are OK try replacing your "brake stop switch". You may have to have either your local auto shop or local dealer replace the switch because it's hard to do yourself. I had the same problem on my Tahoe and replacing the brake stop switch solved it right away.
Be sure the dash illumination dimmer switch is not turned off.
Check to see if the dash lights dim or if the tail lights come on when the light switch is turned on. If these other lights work then check for a headlight relay. Most likely causes are either the switch or the relay.
AnswerMost likely a faulty turn signal switch, or possibly the wiring to it.replace switch assembly.
I have a 99 blazer with the same problem. If i move the light dimmer dial from side to side it will stop. You can change the switch or from time to time wiggle the switch.
It can be your switch or the fuse try checking the fuse first.
