Air Conditioning problem
1992 Mercedes Benz SL500 V8 Automatic 165000 miles

why my air conditioning vents don't work. I hear and feel the air a little from the side vents, and it's very strong from the back vent, but the center front vents there's no air coming out at all!

Do you
have the same problem?

The issue you are describing sounds like a blend door issue with your heater case. This can occur when the doors become stuck or the vacuum actuator or line becomes damaged or fails. This can also be related to an AC pushbutton unit failure.
