Need some help chasing down this problem that I'm having. Truck is an 07 nnbs Sierra. I have no right front turn signal and it keeps blowing the courtesy light fuse. I've removed all the bulbs and ever time I turn on the right turn signal, the courtesy light fuse blow every time. The rear Blinks like I have a bad bulbs in the front but thats not the case. Any suggestions?

 

start tracking the wiring.

 

I don't know where to start. Anyone have a copy of the FSM?

 

any burnt wires right off the plug or anything?

 

Sockets and wires around it is in perfect condition. Funny thing is that the park lights work but not the turn signals.

 

that is strange, ugh i hate electrical problems

 

well you have a short on the power side and thats why the fuse keeps blowing
i\ll upload the diagrams in a minute
