As I have paid some money out I really would like some sort of answer to my problem.
My Hyundai Terracan 2003 blows warm air out if the heater all the time whether the temp. is set at 17 or 30 degrees.
Also is it possible to change the air temp. flap motor/actuator without stripping out the dashboard and facia.
All the other dampers/flaps and fan controls seem to be working ok.
