2007 yukon front parking light and tail light blown fuse

[ARBSR]

My 2007 yukon denali front driver side parking light and tail light fuse blows whenever I open the rear hatch. It only happens when the lights are on and I use the key fob or the button inside. Any ideas on where to start? they are on the same fuse

Start at the bundle of wires that goes from the body to the tailgate.  Also follow the wires from the left rear light to the body of the truck.  There is likely a spot where the power wire to that light is being shorted to ground when the gate is opened.

This is for whomever might still run into this issue, as I just did.

 

Fuse #25 in the underhood fuse block blows when opening the liftgate. The vehicle is a 2007 GMC Yukon XL Denali.

Above the very back of the headliner, the brown wire to the license plate lights was being dragged across a sharp edge on the body. Thankfully, there is a connector right next to it that allows for the harness to be pulled out making repairs much easier.

 

I hope this helps somebody.
