I own a 2011 Santa Fe GLS base model with single ac controls and am trying to resolve this issue with my wife’s ac. When the ac is on the driver side blows warm air sometimes hot air but the passenger side blows as it should cooled air. I have connected a can of coolant with a gauge to the low side ac line and got a reading on the low side of green. So I didn’t charge the system. I then purchased and replaced the driver side blend door actuator. Still have the same issue. If anyone can advise me on what may be going on and how to fix it besides going to a dealership it would be greatly appreciated. Thank you in advance!!
