OK guys help me out here but I think I found the problem. Just took another drive with the a/c on and set on 20 degrees celsuis both wheels and fan wheel set to auto.

A/c blew ice cold for the whole trip, airflow did vary but air tempreture remained at ice cold, before I left I read the inside tempreture from the climate control display the way Jim said it was 28 degrees celsuis, after the ride with the interior ice cold, the inside tempreture from the sensor at the sunroof switch still read 28 degrees celsuis.

So I gather my inside tempreture sensor is busted sending wrong info to the climate controle module, which in turn keeps the compressor engaged for too long which in turn freezes up the evaporator after some time???

Does this sound logical?
