A/C compressor runs on "Defrost"

Colorado is cool and also dry. The A/C compressor runs in "Defrost" mode to dry humid air, which we do not have. I pull the plug on the compressor, or the A/C relay (depending on the vehicle) for most of the year. No need to lose engine power AND fuel economy just to run the defroster in a dry climate!
