Why does my a / C vents blow cold but warm drivers?

It will not be apparent if just looking at freon gauge pressures- they will be normal. But a system that is 1/2 pound low will cause the passenger side vents to blow cool or cold air, and the drivers side to be less cool or even warm on this car. There is simply not enough freon capacity in the system to cool the air to the drivers side.

Why is my AC not working in my Avalanche?

One or more heater & AC (HVAC) air delivery and/or temperature mode door actuator may fail. This can result in incorrect air delivery or temperature. If this occurs, fault code (s) stored in the HVAC control module should be available to assist with diagnoses.

Where does hot air come from in Avalanche?

Intermittantly, hot air comes thru driver’s side when all selectors are off. This can happen when A/C is on also, but passenger side is cold. No codes come up on computer when checked. Replaced driver’s side actuator door once with an after-market product. It’s still doing it.

Why does my Chevy Avalanche blow hot air?

I noticed that the drivers side would blow cold air when the ignition is first turned on, then after about 10 seconds would go to hot. This means the controller and motor actuator are working.
