Question 1992 190e question

I just purchased my first MB. Its a 1992 190e with 90,000 miles. I have a question about the heater. It works but the two center vents blow cold air. I assume they are stuck on vent. Any suggestions?

This is a great car that I purchased and I think I'm hooked. The car gets the best mpg I could imagine as I drive 40 miles to and from work. I wanted a reliable car that would get good mpg and the rice burners were out. I love this little car and its fun to drive. I just wish I could fix this issue cheap.

This is a typical misunderstanding with owners that don't have a manual . . . the center console vent will only provide "non-heated" air . . . which means either a/c chilled air or ambient temp outside air . . . but it won't provide any heater core heated air.

Check under the hood, above the brake booster where there are multiple plastic vacuum lines connecting via rubber tubes. Look for a broken/worn one.

Between the two center vent outlets is a lever. UP is open, DOWN is closed.

the center vent will always blow cold air no matter what. If you want heat you gotta close em. If the little knob is gone try find a new one at a wreckers or get the part from the dealership

Well there is no fix cause that is how it was designed. No Heat will ever ever ever flow out the center vents on a W201 car. Now if it is stuck open then the lever may be disconnected or broken, so you can just manually flip the flap closed behind the vents. Just pull one of the two and stick you finger in there and push the flap closed.
