I came off the lake this evening and when I pulled out with the boat and turned my lights on I noticed my trailer lights wasn't working. The signal and brake lights were working but no rear trailer and side marker lights.

When I got home I hooked it up to the wife's Envoy and everything worked fine. It's my truck!!! >

What gives? Does anyone know if it is a fuse or maybe the wiring? I checked the wires on the truck and they seem okay, nothing is loose or appears to be cut. Do trucks have fuses for the trailer wire hookup? HELP!

happens to me all the time.

i have a 2000 Silverado.

It has a dedicated trailer light fuse under the hood in the electrical center.

Same thing with my F-150.  There's a fuse block under the hood that has fuses for the trailer electrical outlet.

before you check the fuses. check your grounds. then the fuses
