I read your message about the electrical failure in the rear tail lights. the first thing that i can think of is to check your fuses. the fuse box is located in the engine bay on the drivers side, closest to the windshield. there you'll find a black box. open it, there will be a bunch fuses. there will be a white label in the inside which will help you find the bad fuse (if there is one). see if that works.
