my driver's side headlight has been out for a while both high and low. i replaced the bilb nothing, i replaced the CTM nothing. checked wiring couldn't find a bad ground but it is tight in there. anyone have any thoughts?

 

Well, I would have to say the wiring is probably bad. Either the positive or ground wire.

 

did you check the fuses?

 

YEAH I CHECK ALL FUSES THEY WERE ALL GOOD UNDER THE AND IN THE TRUCK.

 

Is your cap key stuck?

 

no the system i use at work uses caps so i forget to switch

 

so any thoughts?

 

Get a multimeter and go to town. Start chasing the wires, make sure there's continuity where there should be and none where there shouldn't.

 

found the problem. it was in the harness to the CTM. the bottom one had a little water get into and it created some corrosion. got some harness cleaner and cleaned the connections. now i have lights.
