Constant hot air through blowers....

[christinho]

Anybody else had a problem with constant hot air through the air vents or know a possible cause?

There's plenty of coolant in the system and the engine temp doesn't go over half way...

Any help/advise would be greatly appreciated...

Hmmm ... my dad has an A4 that was the opposite... could only get cold... the climate control has small stepper motors to open and close the flaps behind the dash that control hot and cold... 2 of these motors had failed... could be that the same has happend to you..... on my A3 if you turn off the engine and the heater blower and then move the temp up and down on the climate control you can just about hear the motor moving the flap...
