Re: ACC Inside temperature sensor 700 87

The unit is called the manual climate control unit(MCC). It's a circuit board, relay and switch device all in one. Very common problem with 700 series. Read 700FAQ's about problem with this unit and common broken solder problem on the circuit board, and it's fix by resoldering broken solder.

I had the same problem with my '92 740 but resoldering did not help my problem. New unit at the dealer $600plus. Salvage yard $150.

Good luck
