I've got a '92 300SD (W140). I had to take the center console apart (as much as I could to fix the track of the sliding center compartment cover). Now the slider on the rear air vent no longer works. As moving the wire actuator at the back does nothing to the damper flap under the radio in the front, there must be a linkage alongside the trans tunnel and under the center console for reasons I could not begin to fathom. I've had the armrest off and I know how to get the wood panel with the window switches off, but I can't figure out how the console is hitched in the back. Do I need to take it off, or can I remove the center compartment from the front, i.e., the space vacated by the panel that holds the window switches (looks like a bear to unscrew the underneath screws)? Or is it done some other way completely? Also, assuming I get it fixed, is there a trick to getting the armored wire hooked up to the vent unit in the back again. Seems like you need very long skinny fingers and my experience is that they don't design things that way—you just have to know the trick.
