Soo here is a though one, i work at a custom police eqip. install company, and have run into a problem that me and my other co-worker cant crack. We were installing lights in the liftgate of a 09 subrb and all worked fine and dandy, then we go to open the door... and it wouldnt open... then we have come to find out that the headlights and turn signals and hazards and fog lights...and we have checked every fuse every relay every ground.. and idea sugestions.... were just trying to keep from bringing it to the dealership ..... let me know...
