on the brake pedal under the dash is a brake light switch. that when you depress the brake it turns your lights on. you might wanna check that
If the brake lights do not work on Chevy Venture van 2000, try to disconnect the brake switch. Then short the two contacts of the connector to check if the brake lights are now working.
BAD BRAKE LIGHT SWITCH AT TOP OF BRAKE PEDAL
The bulbs are burnt out.
on the emergancy brake lever there is an electrical switch, just unplug it they will go off and your fog lights will still work.
Ensure relays and parking brake switch are properly functioning.
check the fuse, brake lights have their own, & check the brake switch at the top of the brake pedal
brakes and running lights have separate fuses. check the fuse then check the brake light switch under the dash
I would check the running lights for one with a short. I had the same sort of thing with my trailer and I spent way to much time troubleshooting the brake and signal wires. Turns out a running light bulb connector was grounding out on the trailer and messing it all up.
The most likely cause is a bad brake light switch (if none of the brake lights illuminate) but if its only one of the brake lights, try changing the bulb. Even if they still work as running or turn lights because they have a double filament and may still work partially, but not as brake lights.
if the tail lights work but not brake lights then its most likely just a blown fuse or it could be the switch at the top of your brake pedal arm.
Hey E==The running lights have a module which may be bad. Good luckJoe
