Ok, I don't know if you saw my post about my instrument cluster going bad. The dealer determined my sequential taillights were the problem. After removing them, the instrument cluster returned to normal. Has anyone else heard about the wiring harness going bad or anything like that? They were the first modification I made to the car back in June and just now they give me a problem. Basically from the rental car, the cost of the 'non-warranty' work of switching the harnesses, and the actual cost of the harnesses themselves, I spent about $500 for something which isn't on my car. Think I might be able to recoup some of the money from CDC cause I have paperwork from the dealer saying that was what they deemed to be the problem.
