stepper motor clicking
ok guys i hate to beat a dead horse here since i know the stepper motors are common problems. I'm just curious if someone can help me out on which one or how many i need. I have no air going to the windshield and no air out of the right vent above the center console. Also i only have heat on the drivers side of the car. I also have no AC but i'm assuming it just needs to be recharged since it's never been touched. Ive had a clicking behind the dash on and off over the past 5 years. Can anyone help me pin point the problem?

There's a link somewhere on this forum (maybe try the DIY section) to the MB document describing the position and operation of each motor. Since you have a C32, you have 10 in total. Certain ones tend to break more often, but honestly it's a crap shoot. My car has 6 motors (C230), and I had 2 linkages and 1 motor fail.
Based on what you're saying, you probably have at least 2 dead motor/linkage combos. It may be just the linkages (MB sells a kit that beefs up the weak linkages - the weak ones fail on pretty much EVERY car), but this job is such a pain that you may want to replace the motors in question, so you don't have to rip half the dash apart again.
If you can't find the document in the forum, PM me your email.
