I bought my first benz during the winter and did not have a chance to check out the A/C system fully until recently. When the A/C is on, it blows cool air through the side vents but hot air through the center vent on the dash. Is there a problem with the control unit itself not shutting off the hot air vent? Or is it the coolant valve that everyone else is talking about? This is my first benz so I have not experience on this A/C system.
