Center console wiring is damaged from I don't know what, it's been like that since I got it. Climate Control, Stereo Head Unit, rear defrost do not work, so yes I'd say it needs replaced. I was thinking about Wire Wizards. They redid the interior wiring on a friends E38 and did a pretty good job. I didn't think this would be off topic since the 500E/400E have similar interior climate control and wiring. I shouldn't have disclosed my vehicle lol, this thread has a higher chance of just getting buried now.
