ACC temperature distribution

ACC system on Auto, say 19oC. Car started cool air from vents all around, 5 minutes later fan power goes down. Another 15 minutes and fan power going up! Still cold air, this time vents to rear passengers blowing hot, very hot air :confused: .

Second problem is say a humid day. ACC on auto keeps windscreen clear. some time later windscreen starts to mist up. Switch ACC off, and then back on again screen clears. repeat every 5 minutes on a very humid day :confused: . Had several software updates and still no resolve.

Not happy any pointers would help as just bee serviced today and told oil leaks around head gasket and timing chain casing. Garage want £1450 incl. VAT :evil: !! Garage advisd that as car a 1999 model and presents itself quite well with the leather etc and is clean I take it elsewhere and trade in. Are they right? Do I call it quits before I spend money?

The £1450 is for the head gasket, timing chain (due at next service anyway) and 6 hours labour and include 10% discount.

I advise you to learn to operate the climate control by hand, mine seems rather dim witted as well. Saab made an amazing ECU, but the climate control could have used a little more work. :p
