159 air conditioning/heating display
My 159 JTI has a recurring problem. The heater/air con works perfectly, as does the display, then the entire display unit shuts down. No lights on the unit, no heating or air action, and the odometer in the speedo starts flashing. My dealer has tried to repair this five times. First they reset the system and later played around with the connections until it all worked. It then works for a while and after some time for no apparent reason stops. Usually on a blistering hot day when you really need the aircon. The dealer now wants to replace the air conditioning compressor at great expense but i don't think this is the problem. Any ideas?
