What bothers me in addition to what Grdenko mentioned is that recirc stays on for only 30min at a time with the AC compressor on (W126). Sometimes you're stuck behind an overloaded motorhome running extra rich for longer than a half hour. In our non-MB vehicles, I don't remember the last time the recirc lever was not in recirc. No condensation or fogging problems.
I can't find a W126 ACC wiring diagram that shows the recirc button so I don't know if the timer is in the button or in the temp control unit. I doubt it's in the button but if it is then convert the button to a simple on/off rocker.
