The foamy connector pipe beneath the dash could have rotted out.

Wouldn't that prevent the aspirator fan from pulling a vacuum at the grill?

Sorry - I missed the bit about the tissue sucking.

Check the resistance of the thermistor - -they have been known to go
bad.

Do you know what the resistance should be? Would I be checking this in
the dome light assembly?

Don't know the spec right off hand (it's in the manuals), but is it
usually in the hunderds of ohms range at room temperature and should
change in response to temperature changes. The interior sensors on
the W124 are negative temp coeffident -- the lower the temp, the
higher the

Mine (SDL) did the same thing - I chased all sorts of things, but it turned

re-solder the PCB. I also cleaned the switches and pot with de-oxit (sp?).
Actually, I bought a spare PBU from Kaleb, re-soldered it, then swapped

This CCU (Climate Control Unit) has been resoldered completely, all
fresh solder. Grrr, I guess this time I'll order new capacitors and RR
them also.
Jim, I'll pull the monovalve tomorrow or Thursday and see if that
helps. It might be the CCU since the auto fan blows high speed or low

That is possible. It depends on if the fan speed is pro-active or
re-active to the plenum temperature. If
Tell me about it. Getting to the bottom PCB is a PITA, having to remove
that small ribbon cable for the temp control. Eh, it's not as bad as
laptop repair, thank goodness.
