I'm Stumped..... No power to dome light - The 1947 - Present Chevrolet & GMC Truck Message Board Network

orneryolbiker · 01-24-2010, 11:41 PM

I have a 91 burb v1500, it is loaded, has power mirrors and rear air with heat and factory remote start, I don't have power to my dome lights, lighter or power mirrors, yes I checked the fuses. I am fairly knowledgeable on these trucks, but this has me stumped. Any help would be appreciated.....

Dome lights are supplied by this orange wire.

And is supplied by this outlet in the fuse box upper left hand side. and the white wire goes to the door pin switches and headlight switch.

The cigarette lighter is also supplied by the same circuit on previous year models but I don't have a wiring diagram yet so I cannot prove it is so on the later models. In my 95 model wiring diagram it shows all three of your problems coming from the "HORN/DM" fuse. So, if you have power at that fuse then you will need to follow the power flow and find where it stops.

I can only say I fixed mine sucessfully and the vanity lights using my Service Manual... So I hope this helps
