If I remember correctly from previous threads this model could suffer from dry solder joints on the climate control. Fairly easy repair to remove and reheat all of the joints. Good luck.

1) Does the blower change speed? Can you set it high to low?

2) When you push any of the control buttons do you hear things changing or moving at all?

3) Have you verified all fuses are OK?

All of the climate control can suffer from cold solder joints. If you are interested I would be happy to re-flow the unit for you. See my link in my signature below for more information.

Well you can stop the heat by pulling the plugs. I would start with a reflow of the CCU.
