Hi,

I'm new to this forum and just bought the new Bentley mercedes w202 c class manual. I can't find the vacuum distributor under the upper left side of the engine bay. The problem I am having is that air will not blow out my center or foot vents. When i push the button on the n/22 climate controller I can here the y/11 changer over valve behind the glove box make noise switching to the different accuators. I've tested my valve dist. block in the upper left side of the engine and all but the "P" connection holds vacuum. I've checked the lines from the intake manifold and they hold vacuum as well. The question I can't seem to answer is whether it is the individual accuators or the block itself? Now when I connect a vacuum pump to the Green vacuum line going into the y/11 change over valve and vacuum the system to 400millibars is holds but when I push the button on the climate controller for the center or foot vents the vacuum decreases by about 20millibars and I have to keep pumping the vacuum tester to make the vents accuate. I've heard of these models haveing similar problems and if anyone can help me out it would be greatly appreciated!! Sorry for the long post I just wanna describe the problem as accurately as possible!!
