I pulled the dome light off to see if I had power to the housing. No power at all.
I wiggled the harness and found that the 2 wires had been cut about 3 inches from the light. This is a clean cut, doesnt look like it got pinched or cut accidently.
Now Im thinking that the PO was blowing fuses and cut the dome light wires instead of looking for a short.
What does the cab roof look like under the headliner? I couldnt find the other end of the cut wires. If I drop the headliner will I be able to find them, or is the roof double walled?
Its doubled all right the wire is fed over and down side and under threshold . You can remove corner cab cover force or fish wires accrossed . Good luck The short was probably under threshold
