Question about 2002 Volkswagen Eurovan
The center air vents in my dash board above the radio don't blow any air at all. I pulled out the small manual air vents and noticed the diverter in the venting system is stuck in the closed position. How do I fix this so that it operates as designed?

The vent flap foam lining has come loose and needs to be removed or reglued . A spray on contact adhesive works best , don't glue the flap to the vent casing.

The heater in your car depends upon a flow of hot coolant going through the heater core in order to get hot air into the car. If the heater core is partially plugged, it will restrict the flow. If you have a head gasket that is putting exhaust into the cooling system, it will eventually get into the heater core. When this happens there is no coolant in the heater core to make the air warm. If the water pump vanes have corroded away the result will be very poor coolant circulation causing the heater to not blow hot air. If your car is equipped with a heater control valve that is not functioning properly, the coolant flow will be restricted. One or a combination of these factors is likely the culprit in your case.
if the car is not overheating, the thermostat is working fine.... replace or flush the heater core multiple times to try and eliminate sediment build-up.

its either the blend door motor or just door is stuck or the switch could be bad to activated blend door motor. Or the the switch is on the heater core lines (outside in engine compartment) may not be functioning but I think your car is too new for that option.

Has the car been changed coolant since it was bought? If it is time to change, let do a flush through a heater core. There are 2 coolant hoses going thru a fire wall. One for coolant in and one for coolant out. Heater only works if coolant is flowing through the heater core. Therefore, there are one or both following cases contributes to the problem: 1-If the valve control coolant flow gets stuck, then it always closes so there is no heat. 2-If the valve is working, but the heater core gets clogged up, then there is no heat.

I believe you are correct. The cable running from the thermostat control knob to the vent lever can disenguage from the vent assembly. You can remove the plastic side panels below the radio/heater housing to see the cables. Move the heat/cool knob back and forth to locate the correct cable and see if it has fallen out of the vent assembly.
