2009 Chrysler 300 AC only works sometimes on Driver side

[Deel]

Need help diagnosing an issue with 2009 Chrysler 300. Air conditioning appeared to stop working the other day and I thought it was dead. It seems though that the AC will come on ice cold on the driver side every now and then, yet the passenger side and rear remain HOT.

What could this be? Are there any fuses to check and how would I repair them/take them out safetly?

Venza AC driver side

You’re kinda missing the main point. The AC is working fine on the passenger side. Warm air comes out the 2 vents on the driver’s side only, normal cold air comes out of the passenger side vents. Since there aren’t 2 AC systems, hard to explain 1 side working and the other not with because freon is low. Thx anyway. Although that reminds me that there is a 3rd vent for the back between the front seats and it blows warm air, too. Doesn’t make sense to me unless I’m missing some other heater contr…

It is most likely the blend door actuator - a common failure on Chrysler/Dodge vehicles.
