Why does my AC go from cold to warm?
If your A/C flip-flops from hot to cold and back again, your expansion valve could be failing. The expansion valve distributes the proper amount of refrigerant to your evaporator. If the valve is blocked, the refrigerant flow could be restricted or could be too unrestricted. Your A/C blows warm air.
Why does my car AC work intermittently?
Intermittent cooling is often caused by the components of your vehicle’s AC system freezing up. Typically an iced over evaporator is the culprit. There may be numerous issues causing the icing—from a dirty cabin air filter to a blocked evaporator drain or an overcharged system.

What kind of refrigerant does a Subaru Forester use?
Never before encountered this but ok, it’s been r134 refrigerant in previous cars. This new stuff ought to be very very environmentally safe if it leaks so easily compared to earlier refrigants. It must be made from liquid gold or something as it is so expensive.
Why does my Subaru air conditioner shut down?
So, the radiator kept the engine safe, but when the fans were kicking on, they were blowing A LOT of hot air at the evap unit. That would trip the AC temp sensor and shut down the AC. Yes that will happen if the radiator is clogged enough to limit air flow, thus not allowing the proper temp drop needed to take the heat out of the AC system.
