Bought car in Maryland, everything great running still is. Just started having issue that AC button light stays on. I can hear compresser running, it's blowing cold air, but I'm unable to switch it to heat. Whenever I turn fan on light stays on and AC blows cold air, it's getting chilly in the mornings, needing a little heat to get windows cleared. any help would be apreciated.
