AC compressor won't stop
Whenever my heater control is on anything but off, the ac clutch continually kicks on and off. When I use the defrost I can see the clutch kick on for a couple seconds then off. What is causing this?

Check the refrigerant pressure, if it is low the compressor clutch will continue to fluctuate like you are mentioning. I had this problem during the summer and found I had virtually no refrigerant in the system. I took the system apart, cleaned everything good and converted over to R134A. After servicing the system everything has worked fine.

Re: AC compressor won't stop
That's what is what it should do. The compressor running isn't dictated by the temp selector. It (a/c compressor) will run when set to max, norm, bi-level or defrost.
