1996 brake light switch on gmc - 1996 GMC Sierra

hi, sure its not the brake lights that are staying on, remove a wire from brake light switch under the dashboard above brake pedal, if lights go off renew switch etc.

possibly the neutral safety switch connected to the brake pedal is bad. when you apply foot to brake , shouls hear a click with key in run position, this would be the safety solenoid retracting itself from shift linkage, allowing shift lever to move. try pumping rapidly, but easily the brake pedal to see if you can hear click, and or shift from park.

not coming out park may a couplr of things brake switch there also a switch under center piece where the shifter is a ***** probe with test light or multa meter u can see if getting power if not getting power you want look at the key swich the mancanical side or eletircal side can be bad

here is a wiring diagram. Are the bulbs for sure good?


hope you can read it.

the brake lights have a brake switch on the brake pedal. they do not go through the multi function switch. Did you check the brake fuses, and if they are ok make sure you have power and ground at the brake lights.

The first place to start is with the fuses, make sure all fuses are good, then move on to the signal light switch, brake lights run through signal switch but this sounds like a fuse or the switch.

check fuse
if fuse is good check brake pedal switch
check grounds

The brake light switch is at fault. Get a new one and replace it. The location is at the brake pedal area mounted on a bracket with a plunger stud that rest on the brake pedal's arm the pad is attached to

check the conectors in the fender wells

It's unlikely the turn signal switch. Try disconnecting the switch mounted directly above the brake pedal. If the light turns off the problem is in the brake switch. They commonly go bad and can be picked up at a gm dealer for about $15.
