A Question: Does the compressor cycle off/on when the Air Cond. is in Auto mode and the preset tempurature is reached, or does the fan just slow down and warm air is added to the mix to maintain the selected temp.
related: is there a way to link or make the driver side thermostat be the only one that needs to be moved to set the whole cars internal temperature? on some cars you can disable the pass. temp control and use just the drivers control to set the overall temperature.
