Break and blinker
All lights work on 2005 gmc 2500 van, other than
passenger rear, break and blinker. Bulb is good,
fuse is good?????
I had an issue with the rear wiring harnesses losing the ground. The rear lights wouldn't work if the headlights were on. I replace the two rear harnesses and the situation was fixed. I have a 2001 GMC 2500 cargo van with a 5.0 liter engine.
