No A/C on drivers side

[426ted]

Hey all, posted this in the Full Size Forum, but it quickly got buried with no replies. Turned on the A/C for the first time since last fall to a nice cool 16 degree. Drivers side blows hot air, passenger side is ice cold. Adjusted the dual climate control, turned the passenger side off etc...Cannot get cold air out from the drivers side. Stuck vent door somewhere maybe? Truck is not due for servicing for another 2 months, so I'd rather see if this is something that I can fix. Any ideas? Thanks.

If it's under warranty take it in. Problem is likely an actuator
