Needed Heater resistor that goes on the side of the blower motor.
Just incase you cant get hold of one they are £31 from VW, i just found out half hour. Didnt buy it though.
Thast quite dear, do you know the part number :) ;D
Try 867 959 131. From an old reciept (2001). I only found it easily because I know it was one of the first jobs I did after I bought the car, and is therefore at the front of the file!
Cheers dudeeee
