The **** control activates electric motors that control the vent doors.
Based on airflow, determine if the dash vent door only is stuck open. As when you select another vent, air now flows through that vent but at a lesser rate then normal because the dash vent door is not closing. As opposed to no or very little airflow.
Motors can be replaced (a common issue) but access can vary depending on which motor is bad. You'll need to get some service info to fix the problem, suggest a Haynes manual or trying to find service documentation on the internet.

You need to determine which vent is the problem, then check out the servo motor.
The vent selection servo is located on the drivers side of center climate assy way up under the dash. Not sure you can see it but if can, observe its operation when you select the climate vents.

If the heater blower works, then the climate system is receiving power. The issue then becomes the selector switch or the servo. The switch is simple rotary type. The issue with the servo is removal for testing as the manual states the dash needs to be moved to access.

Thanks, Joey I saw a video of the servo being removed by pulling off panel to the right of accelerator and then removing air duct #3 but the guy admitted to a sore neck and back after he replaced it. Anyone have any idea of the cost of dash removal and servo replacement..?
