The car (`88 750iL) also has another problem. I can`t get the blower to work. I also tried to put it on defrost wich should switch it to the higest stand but to no avain. This week I got another control unit wich we tested on another car and it worked fine on that car but in my car the blower still stays dead. Very anoying in tthe winter and also with nicer weather coming up cause the airco needs the blower to. Any help is greatly apreciated.
