With A/C on. Passenger side blows cold air, drivers side blows warm air. I found the actuator on the left side of the air box that was not working and replaced it. How do you set the disc that the actuator moves to open and close flaps in the air box? Right now it is still doing the same as before I replaced the actuator.
