I too have posted this question recently, and even after much research in the archive, am still not convinced it is the heater control valves, but the heater core valves? My AC works fine with no heat out of defroster while AC is on, and left / right seems to be working fine also, so the archives have led me to this conclusion. Any concurrence? If it is the heater core valves, any recommendations on cost and effort to repair or replace? THe defrost in the front is blowing out hot air while fan is on. I think is the heat valve problem. ANyone has the direction to replace the heat valve? THanks!
