Well, it seems that the vacuum lines coming out of the little manifold were not in the correct order! and according to the diagrams I have found, the numbers the diagrams show on the little manifold and the corresponding vacuum lines not coincide with what it should be. I went by the actual drawing, not numbers/vacuum line relationship. also, the diagrams are kind of confusing, as they show that the vacuum ports labeled, from the source vacuum to the right or to the other side of the manifold, as 2,1,3,4. On the actual manifold the order, from source to right as 4,3,1,2.It show the line going to the fresh air/recirc button as coming from the port labeled #4, when on the actual ,manifold in the car it comes from #2, etc.! either that or my 1987 560sl is some kind of really ass-backward! However, attaching all the vacuum lines according to where they go looking at the picture, not using the numbers, everything works as it should, like the fresh air only working in a/c mode, etc. once I am finished, I will make a diagram/pictures and post it.

Like I said, maybe my car is all backwards, or the diagrams from the repair CD are screwy, I will find out once everything is back together!
Also, the labeling on the diagrams, I can't really tell what color combos. the lines are, maybe labeled/abbreviated in german? anybody else found ot this to be true?

Thanks,
