On another note, the odo seems to be working reliably through a hundred miles or so (fingers crossed).

Also, I had been trying to diagnose why the blower motor was on full blast at all times when the heat was on. At one point I had taken the hvac control module out and checked the solder joints inside and it looked brand new (I found in the old receipts that the PO had bought a NEW one). I checked all the switches, wiring, etc and deduced it maybe the "blower regulator" (forgot about it after I saw the prices).




After replacing the monovalve, the blower motor actually returns to low speed once the cabin is warm. No more annoying "blowing" noise while driving (she likes that )

Was the climate control just not sensing the heat requested so it was kicking the blower motor into high speed? Makes sense, but I just don't know how "smart" the climate control is (or thinks it is). I wish I could sit in a w123 with fully functioning climate control so I could see all the features and compare them to mine.

In any case, an unintended bonus problem solved. Those are always nice.
