2003 STS - No power on trunk lid harness
I have a 2003 Cadillac STS and all my brake lights on my trunk are out , and the power Trunk hatch and everything having to do with the trunk lid is out.. Although the lights on either side of the trunk work.. What could be the problem.. I don't think it's a fuse issue because multiple fuses run the lights

Re: 2003 sts no power on trunk??
Common problem. The trunk lid wiring harness runs inside the plastic cover for the left hinge/arm. Pull the cover and check for chafed/broken wiring at the hinge area. Also, check the multiple ground block at the left rear fenderwell body metal - under the molded carpet area.
