passenger side vents suddenly start blowing cold air when heat is on. Driver side vents still blow hot air.

Center vents do not blow. I can change the controller settings to try to redirect but the air flow does not change. Blows out the two side dash vents and defrost only.

A/C blows fine, but blower is stuck in defrost mode, and won't blow out the regular vents.

Air does not flow from the center vents. MB dealer said it was the air-conditioning actuator, which needs to be replaced. They said it is a $600 to $800 repair at the dealership and could be fixed for much less at an independent shop (recommended that due to the car's age and value, especially since its not a critical safety system).
