I have been having trouble with my right tail light. It functions normally with the lights off, but when turned on it will not show braking and the turn signal will not function. I have already checked the wiring and the bulbs and can not see any problems there. I had removed the housing earlier in the year to install guards on both lights(which by the way is a real pain in the ass to disconnect). Any ideas for trouble shooting would be greatly appreciated.
Thanks

Turn signal switch.......

yep, that had me scratching my head for a good two days and many foul words coming out of my mouth....
One of them GM column wire harnesses fit in nice too if yours is a rats nest.

[/ QUOTE ] Check the ground for that tail light. It may be back feeding voltage through the turn signal switch. The light will not come on with opposing voltage. (12V from both wires)
If you have a Volt meter. Check for voltage at the GROUND wire at the tail light to ground with the LIGHTS ON. IF you see voltage greater then 2 volts your ground has too much resistance therfore is not good. If you don't have a Volt meter, Use a test light on the ground wire with the lights on. If the light comes on, the ground is no good. Since your directionals do not work at all. My guess is that you will see >10V. Your ground wire may be off all together.

I hope this helps! Let us know what you found.
