[W126 Coupe] speaking of AC problems...

[Dick Spellman]

Sounds like your pushbutton control or vacuum switching valve has a 
problem Richard.  If as you say the vacuum elements are all okay.  Try 
giving the harness to either side of the ACC push button unit a wiggle 
to see if it's the famous solder joint issue.  You may luck out.

Yes, the rear center cabin vent only pulls outside air so you can slide 
it closed during extreme hot or cold weather as you see fit.

I know the vacuum switched directly behind the glovebox are ok. Also, does the rear center vent blow cold air our outside air? Because mine blows outside air.
