    Default left side light dont work on trailer

    Hi guys new guy here

    Testing my trailer light today and found out my left side doesnt work on the trailer. Tried to trace it to front off the truck but lost it. Is there a way to test the wiring from under the hood? Hopeing to take care of this today going up north tomarrow for the big week end

    Thanks Joe

    What exactly does not work, turn,stop,tail? Some or none? Do you have power for the lights at the truck connection? What connector are you using? I think there is a sticky that tells what pin is what and you could start looking from there.
    found the sticky, it is in the audio/visual electrical forum here is the link http://www.gmtruckclub.com/forum/sho...agrams-Pinouts

    Steve could very well be correct. On from around 2000 on up trucks, there are separate trailer light fuses in the underhood fuse panel for left and right trailer lights.

    Looking at the Haynes manual diagram for 2000 yukon and there is indeed a seperate fuse for front, back, left and right stop/tail/turn but these are for vehicle lites only and does not indicate a trailer connector assocciated with them. It does show a TRL PRK FUSE 15A and only notes that it's for "trailer wiring provision" located in the underhood bussed electrical center.
