brake lights problem, help!!!
This might be easy for some of you, but my passenger brake light dosen't come on. My driver side does. I thought they were wired together, but obivously not. The fuses look good. Thanhks for your help. By the way, yes the bulb is good.

I will assume that by the blub is good, you know it has 2 filaments and the brake 1 would work on the driver side, sooo, I would start looking for a bad ground connection on the passenger side. If the tail lights work on the passenger side, you may have a problem in the brake wire. Good luck.

:iagree: check for a good ground. Use a test lead to connect the housing to a good ground and see if the light comes on. Do you have a 12 volt DC test light? check the hot wire into the lamp fixture to be sure it's hot.

I had a similar problem on my 77, the parking lights would work but the blinker and brake light would not, the bulb was fine. Then I noticed my side marker light was out. I went out got a set of bulbs for the tail lightt (sometimes you can't see the break in the filament) and one for the side marker. Pulled the marker light, bent the prongs outward a little to ensure good contacts and plugged it in. Voila my tail light started working just fine. Go figure :crazy:

Re: brake lights problem, help!!! (Madmikeee)
That's a good thought... Since the turn signal interupts the brake light, a burnt out bulb in the front would stop the brake light from working it the right signal was on. The system is kinda quirky when it come to bad grouns also. A bad ground can play all sorts of tricks when it come to finding the problem. The wiring harness has grounding "clusters" so the ground that is bad may not be to the body like metal bodied cars...Every item has a seperate ground wire...All of the little grounding straps should be checked as well. When these grounds are bad all sorts of wierd thing can happen. :chevy
