Hi, I have a 10/91 E36 318i and none of the buttons on the ANALOG air con controls work. The system is charged and works perfectly if the air con relay is forced on. Yet the Air Con, Recirc and Rear Defrost don't work at all. I have checked all the associated air con fuses in the underbonnet fuse box and all are good. Any suggestions on where to look next?
Cheers, Pirate.
