Jc0105...curious..were the headlights on when power lift gate didn't work ? Also...how old is your eng. battery? Why headlights have to be removed is a good Q ? Look for updates.
Try cleaning it first. Little baking-soda and water.So I popped the hood this afternoon to take a look. The previous battery had some corrosion at one of the terminals. Looks like it also damaged one of the cable after the terminal. I’m pretty sure that’s the problem. Need to lookup the manual to see if I can replace it myself this weekend.
