My 1987 300E air conditioning blows very strongly from the two side vents with only a feeble amount of air drifting out of the twin center vents, hardly enough to even feel. The manual roller on the outside works fine to open and close the shutters.
I suspect a vacuum operated valve is stuck closed; it has never worked since I got the car in 1999. How do you get in there to check things out? Remove center console and radio, or is it an even worse job?!!
