We have a 2005 Grand Caravan with the infrared automatic temperature control system. Whenever the system is on, even in the winter, the a/c compressor appears to cycle on and off. Isn’t the cycling only to happen when the a/c is and/or the defrost is on? Thanks. I never have any luck trying to use the Allpar website.

I don’t know about your car. My Lincolns with auto temperature control run the AC compressor 100% of the time, summer or winter, and that is how the system is supposed to work.
