86 300E ACC Problem Part 2

Well got the compressor going and it pumps cold air..Yeah!!!!.....

BUT.....The center vents do not work on A/C all the time....Cold air does come out the 2 outer vents...but if you press on the gas pedal (low Vaccuum) the cold air w/ come out both the side vents and the de-frost vents, let your foot off the gas and the cold air comes out of just the side vents....????...sounds like a vaccuum leak ???....AND THEN the cold air w/ come out of the center vents sometimes.....Any thoughts on where to first start???

I hesitate to tell you what you most likely already know, especially since I have (thank goodness) never been under the 124 dash. It is most likely a leaky actuater diaphragm, but check all the exposed vacuum lines and connectors closely. There is a mess of them up under the cowl behind and above the master cylinder. Failing finding the problem there, it's not too much trouble to get the under dash panel down, so maybe you could get lucky and find a rotted or disconnected vac line there.

Best of luck,
