All- If you do figure a way to control the compressor, don't forget to turn it ON from time to time over the winter; saves the seals.
BTW, Prfct, I don't think the compressor cycles much if the heater temp is turned up, and the outside temp is low.
At least the six can handle it; my old Scirocco with air felt like someone pulled a plug lead off when the compressor ran. I always turned off the air before I passed someone on a two lane.
