AC not working properly.

This morning in the higher elevations of Tucson it was 40 this morning. I put on the heater for the first time and all was well. Then on the way home today it was in the 70s. I put on the ac and the passenger side got cold. But the drivers side is acting as though the heater is on. What is the possible culprit? Thanks

It’s dual zone, did you change the temps for both sides?

Yes sir. Even tried playing with it multiple times. I was reading there are vent door actuators and the drivers side one is known to go out. Blend door actuators.

Yes, probably the motor
