Exposed wire in the rear that was rubbing against metal. 10 minutes to fix... WHy didn't they find it the last time they took the back bumper off? Beats the hell out of me!
They shined her up all pretty again and I get another car detail in a month, so I am not complaining. I printed a few of the links I found to fixing the probolem and they were greatly appreciated by the crew at Body Works Plus!
Thanks everyone, this thread can be officialy closed, my problem is fixed!!!
