.....but when I was first looking for an MBZ diesel, I always had a special liking for the older 240s with manual shift, rollup windows, manual sunroof, and especially lever-controlled heat/AC vents....how simple.

I had non-operable center vents too, about a year ago....I was lucky to find the problem very quickly ...one of the little vacuum swithover valves (in the row of five) behind the pushbutton unit was bad. I got a replacement from a local junkyard for a few bucks.

Good Luck
