We have a 2004 Cabriolet that has been having ongoing issues with the center and right tail light. The center tail light doesn't work at all any longer, and the right tail light works part of the time, and part of the time it doesn't. I've stumbled across a couple posts mentioning bad grounds causing this. I pulled the right tail light and everything looked fine that I could see, but I don't know where the ground connects to the frame. I assume within the trunk area behind the liner? These cars liners seems 10x harder to pull out then my Cobras... what's the trick? Am I even addressing this issue correctly? Also as for the center tail goes, I have no idea where to start... the deck lid liner seems impossible for me to get out, and I don't know how to pop off the light.. Anyone have a write up for this task, or another thread they can reference? (I searched, and searched, and found nothing substatial.) Thanks alot for any assistance.
