Ac problems.

Hi I've got a Gtv jts. The ac doesn't come through cold. The compressor is working at the pipes are freezing. I've changed the heater control unit once and it worked brilliantly. But I changed the rad and it's stopped working again. I've changed the heater control unit again but no joy. And that's just papering over the cracks anyway. Could it be a relay or something?

Many thanks.

You have a stepper motor (on fan/heater/AC unit) which regulates the flow of hot/cold air maybe the stepper motor is faulty, you also have one temp sensor in the wing mirror and one inside the car (with an small fan) that might behave badly.
