2017 Buick Encore - Rear heat is wonky

The rear ac is blowing hot air when trying to get cool air, never used it before today. doesir need freon or what?

Sorry, but I can’t check it from here. The hoses on my gauge set just aren’t that long. No one can tell you the state of charge in your system over the internet.

Highly doubt front and rear AC are two totally separate units, therefore unlikely low on refrigerant.


Hi Shep. I test new cars for Car Talk. One thing I have learned about SUVs with individual rear systems is that you can be driven crazy by the rear HVAC system being set to something you don’t want up-front. I hope it is as simple as closely checking the settings back there.

The blend door actuator that directs hot or cold air from the vents may be defective.
