Anyone ever successfully R&R'ed a climate control servo
I have a 1979 300SD. The servo is not working now. If I spray wd-40 in certain openings that will get it to work, but I have to remove it to do that. I did that again this morning, which it worked after that, and now this afternoon it is not working. It is not leaking at all. If there is low vacuum, will it open and close properly? Also, could the amplifier be bad that is behind the glovebox? What should I expect to see if/when I open this monster?
