Probably a misadjusted or defective brake light switch.
turn signal switch needs replaced!
I know that on my 1998 Silverado, if I but the parking brake on, the fulltime headlites turn off while I'm sitting and idling.
i have tail lights but do not have brake lights nor do i have turn signals. i have replaced brake switch and all bulbs
No brake lights but turn signals work? Turn signal switch brakes route through it.
Its the steering colum
blown fuse or turn switch bad
Not sure how to while you're driving, but if your parked - press in on your e-brake, turn your car off, then turn it on and your lights won't be on. To turn them back on, simply release the brake.
either dimmer switch or blown fuse If you are saying that the tail brake lights are working but the third brake light is not....It may be a defective turn signal switch in the steering column.
have you checked your fuses?
I can't turn the yellow brake or parking lights on my 1998 Chevy blazer off and it's draining my battery.Could you please tell me which fuse or switch I'd use to disable the front yellow lights? This is happening even with the car off.
if turn signals are working , and brake lights not working, i would replace the stop light switch on the brake pedal
the blinker switch shorted out the brake lights... really really common problem, need to replace the switch
