Odd Climate Control Bug?? (99 E36)

Hey all,

I have a 99 E36 M3 cabrio with the digital climate control (I think this was just stock for anything past a certain year). Recently, I have noticed an odd intermitent behvior. When I start the car, the amber LED display for the climat control will be REALLY dim and none of the controls will respond. If I turn my car on and off enough times, it will go back to normal. Has anyone ever seen this??

Ya, it's pretty common on E36's...same thing happened to mine. Your heater control unit is toast...needs to be replaced. New they go for like $450 Canadian. I've got a rebuilt one I'm selling if you're interested for $220...see pics below. They come from the dealer without the buttons or the cooling fan, but these are simply taken off your old unit and installed on the new one. Let me know.

It sounds like something inside is shorting out
take it apart and blow out any dust inside of it because fixing it could be as simple as that. (believe it or not!)
