DOME LIGHT HELP

[34_chevy]

I HAVE A 1997 GMC CREW CAB 7.4LT 1 TON DUALLY. BOTH DOME LIGHTS WILL NOT COME ON AT ALL. MY LIGHTS UNDER THE DASH WORK AND IN THE DOORS WORK FINE. I HAVE PUSHED THE DOME OVERRIDE BUTTON AND NOTHING HAPPENS. I TOOK A VOLTAGE METER AND I HAVE POWER TO THE BULB AND THROUGH THE BULB. I GROUND OUT THE WHITE TERMINAL SIDE AND THE LIGHT WILL COME ON BUT WILL NOT GO OFF WHEN THE OTHER LIGHTS GO OFF WITH THE TIMER. IS THIS THE DOME OVERRIDE SWITCH NOT PROVIDING A GROUND OR SOMETHING ELSE?

 

FRUSTRATED

 

I ALSO HAVE A PROBLEM WITH THE GAS GAGE SHOWING WAY PAST FULL ALL THE TIME, BUT I ASSUME THAT IS A DIFFERENT PROBLEM. EVERYTHING ELSE WORKS GREAT.

 

THANKS,

RICK

I replied to your other post in the other forum category. All the defeat switch does is take away any ground form the door swiches. The interior lamp control module will turn out your lights, so if you have a straight ground, it should be on all the time (like you said it is).

I would turn your dimmer up all the way and see if the lights come on, and/or jumper the dimmer.

My first thought would be a connection on the back of the light switch. It does sound like a ground problem. The door switches work by ground only. Start there at the door switches. Use a continuity tester between every connection for ground.

Also check the fuse now. It's also possible that a short has occurred sending positive voltage into the ground circuit blowing the fuse.
