Air Conditioning problem
1984 Mercedes Benz 300cd 4 cyl Two Wheel Drive Automatic 200, 00 miles

I have an '84 300CD turbo diesel, and a '94 300SL both have had recent work done this spring. No major repairs, just general up keep. The problem is that now neither center vents in both cars work. Both side vents work well. Is this a problem with a simple solution, or will this require more time in the shop? Thank you for your help.

It is to coincidental that both vehicles are suffering from the same problem, specially when they were both in the same shop. Check under your hood make sure all vacuum lines are connected, especially the ones that go inside the cabin.
