2006 Chevy Express 6 cyl Two Wheel Drive Automatic 46000 miles
When I got this van the dome lights in the cab and cargo area did not work. After alot of research I found the problem was the TCB2 fuse in the box under the hood was blown. I replaced that fuse and the interior and cargo lights worked fine. As soon as I put the van in reverse the fuse popped again.
As far as I can figure out the interior lights and the backup lights run off the same fuse under the hood. It would seem to make sense that somehting in the backup light wiring is shorting the fuse out.
I tracked the wiring harness back through the cargo area to the drivers side rear pillar. The wire harness splits off to go down the pillar to power that driver side brake light assembly. On one of those harnesses I can see where someone has spliced a light green wire and added another wire that is running down inside the pillar to a unknown location. The wire is tight and I cant see what it is going to.
It doesnt look like it was done very well. The light green wire had been burned to slide the insulation back exposing the wire. Look to be they then wrapped the blue wire around the exposed green wire and taped it off. I have read in some cases that adding a new ground to the rear tail lights helped fix a problem with those lights. I dont know if that is the case here or if someone wired in something extra off that wire that is now faulting.
Any help or ideas if Im looking in the right place or not would be appreciated.
