the fresh air vent is stuck open r the hose is off on back of vent vent should pop out to reconect

it's a compressor problem , u have to change it.

We have this fairly often on our gm fleet with dual air controls. Replace the actuator and you will be good again (for a while!)

Sounds like there is a crack in the vent that leads to the drivers side, and hot air from the engine is leaking through.

you cant adjust it ,this requires the dealers computer to re set it,or a phyiscal control has packed up like a vacumn pipe has split where it pushes onto the valve that controls the flap in the heater unit.

No ductwork [to the lower vents] under the dash. They are part of the heater core / blower housing is integrated (all one piece).

After reviewing shop manual, we suspect that one of the three damper flaps is not positioning correctly; or debris has blocked one side (which makes more sense given the symptoms).

We're waiting for the temperatures to get back in the plus numbers to check out the physical arrangement.

Its just a vent damper plate not operating, it's like a gate which controls the flow of air,,usually they are operated by vacuum, or cables.
Service center time, unless you are handy with your own repairs.

Temp. actuator stuck on heat , probably . Manual or automatic climate control . Electrically controlled temp actuator , or the door is stuck in heat side.
