If you look unde th ruck on the lh frame going across right behind bumper there is a board that can go bad. The brown wire is the taillight wire and you can either use a test light or volt meter. Yes you have to pull the taillight off which may be two screws. It can also be a bad socket in tailgiht. The ground for these is on the side of lh frame at the very back of frame and that may be the problem but I kind of doubt it.

Does it blow without turning on the headlamp switch? I'd take the wiring connector loose from the headlamp switch. Find the nultiwire connector at the rear, for rear lites, take it loose. One of the wires at connector should be hot all the time, use testlite, between voltage wire and brown wire, for a quick test, if the testlite comes on, the brown wire is shorting to ground.

My 1994 Chevy Suburban's taillights and brake lights do not light up, but the 3rd bight brake light does work. Also when the turn signals are used the signalls in side the care blink very fast and the ones on the outside rear do not work at all. What is preventing all of these lights from working all at once?

Hi:
Replace both brake light bulbs. They are burned out causing the signal flasher to run super fast.

If this doesn't help, let me know. But, I'm 99% sure it will.

Hi:
Unless there is a short in the wiring to the tail lights, new bulbs should take care of it. If you want, check for power to the socket prior to purchasing the bulbs. However, the bulbs should do the trick.

Let me know how it goes.

I have an electrical problem with my blinker and my brake light. In the rear light panels, there are 3 bulbs. The headlights work for the top and middle bulb, the brake and blinker for only the middle bulb, and reverse gear lights for the bottom bulb. The headlights are working, both bulbs and the reverse gear as well, however, the brakes and blinker are not working all the time. Every now and then, they work, and sometimes not. And when they arent working, the headlights are still working in the middle bulb as well. So I have been able to rule out that it is not the bulb. But I still dont know what the problem is. Please help.

Pull the bulb out and inspect the prongs in the fixture itself, they can partially break and or weaken and loose contact with the bulb electrodes. Fairly common on 10= year old GM's. May need to replace the whole light board.
