When I turn on AC and push max AC on...I get Luke warm air on driver side of car and passenger side is cold. I don't have dual climate control. I have found and watched blend actuator move with each temperature click change on temperature dial. My vents all cycle through the dash floor and defrost ok. I also see actuator move for recirculation of air. Can it be the air blend or a.c. charge. I knew it was good but will check tomorrow on AC charge.
