Stupid question but what does the water valve assembly even do?
It uses vacuum to shut off hot water to the heater core when the air conditioner comes on.
The hose that can screw you up is the small hose going to the water valve
Not if you follow the chart!
Water Valve: Not just when AC is on but when the temp slider is all the way to cold. There is a vacuum valve on the slider that closes the water valve. So you can run AC with some heat to get rid of steamed up windows in colder weather.
AAAAAAhhhh. Said the blind man to his Deaf son on the phone.
