Question about 2000 GMC Sierra
The trailer brake lights stopped working. There is no current to the plug on the factory installed trailer plug. The turn signals work and they are on the same prong in the plug (yellow wire). Tried swapping out the brake controller but didn't solve the problem. Also checked all fuses. Any ideas what to check next?
Try checking all the snap in connectors on the back side of the plug,
some times they get loose and/or corded.
if those are good you may have to run a wire trace. i'm not sure how much that would be, i charge 50.00 normally depending on the vehicle.
