I have a 2003 Tahoe LT with front and rear AC/Heat.

Today the driver side dashboard two vents started blowing hot. The passenger side blows cold. The floor blows cold if I select it. The rear AC blows cold. I have automatic left and right temperature control set by the two knobs for temperature and the button for auto.

The passenger side will toggle between dashboard vents and floor vent(s).

The defrost blows hot anyway you do it. My main concern is to get the two driver side vents blowing cold again when I select upper. What do I call the actuator for this and what is the part I should ask for. I plan to have someone else do the work as I can not get down there. Is this a hard job to do? thanks a million.

Blows cold everywhere I want it but upper dash vents driver side.
