Crazy fix worked for bout a month(rewiring the stator of the solenoid) then, issue came back, HEAT out of side vents with AC blowing out middle vents. I can't seem to come up with any solutions other then a NEW valve. The orig. PIC I showed was NOT from my car, I thought it was the same but it's NOT. My part has heater (mono) valve and the Aux. water (elec.) pump all in one, crazy expensive part at the dealer and can't find it used. Does anyone know any work arounds with maybe doing anything different or loosing the aux. water pump part of this valve, and replacing with just the heater valve. My Mercedes part number is 000 830 4084, OEM calls it simply a WATER VALVE. This is a VERY complex part when combined ALL IN ONE! Thanks guys!
