Good Day All, I just purchased a 2005 Tahoe 4.8l, This is an ex-Police vehicle I got it at an Auction it has 160,000 Kilometers. I just noticed that the head lights won't come on...I'm guessing that when they uninstalled the revolving lights etc that something got unhooked and was not put back....
Any thoughts?
Thanks Sean

 

Welcome to the forum. Probably have to just start at the headlites and start tracing the wiring or use a multimeter and start at the switch and see where you loose 12V.

Someone else here may have some more ideas.

 

possibly headlight relay

 

Thanks, I will start at it next week....

 

I found the problem underneath the engine compartment fuse panel. Wires had been cut, for the the revolving lights I assume. Got the lights working but not the day time running lights. There is another large red wire cut that is coming out of the harness but it is not obvious where it goes. Does anybody have a wiring diagram for this fuse box or the DTRL....
