      I turn on the auto feature on the climate control knob and the AC immediately turns on (button illuminates). While I was taking a road trip, I turned the auto knob on. The outside temperature was 25 degrees while the temperature control knob was set to 80 degrees. However, the AC switch still remained illuminated. Is the auto feature working correctly? BTW, if you turn the AC button off, it immediately turns the auto feature off.
