I’ll order a new actuator as I’m sure this fix is just temporary.
Why does my HVAC blow cold air and hot air?
Drivers changed air temperature far more often than they change the mode (defrost, floor heat, dash vents, etc.), so the temperature actuators generally fail first. When that happens, the HVAC system can be stuck on blows cold air or blows hot air. In a dual zone system, you wind up with a blows cold one side, hot on other side condition.
How to diagnose blows cold one side, hot on other side?
