Hello All, My AC was freezing me out one day and then coolish warm the next. It gets cool-cold with the AC on but not like before. We had a very chilly day the other day so I switched off the AC and the recirculating switch but the air coming out was very warm. I’m wondering what might be the issue. I was suspecting the valve that closes the coolant from the heater, but I really don’t know where to look. Any direction / advice would be sincerely appreciated!
