Not sure about 2011 Jeeps but my last car the A/C would cycle when in defrost even with the A/C off. The technician gave me some reason for it but don't remember why. Call up the service department and ask them.

Are you sure it's not the fan?

I believe that if the switch is in defrost, the ac unit cycles to dehumidify the air blowing on the windshield. At least that's what I've been told. Try switching your controls to straight heat instead of defrost.

Up until 2010, at least, the compressor will only cycle with the a/c on or in one of the defrost modes. The only other time a compressor will do this is if there is low "freon" (or whatever is in there now). But, as others indicated, make sure everything is off and you're not in auto mode. If it still does it check with the dealer because it doesn't sound right. Maybe something was changed for 11 to make it cycle in order to keep the oil flowing and seals lubed.

This is correct. It's to keep you from blowing moist air on to the inside of the windshield, which kind of defeats the defrost mode.
