Thanks for the info on the evaporator, but if any part of the A/C system were faulty, I would think that the blower would still put out cold air on "vent" mode. Because I get hot air on ALL settings, including the vent, I'm quessing that it has more to do with the cars inability to cut off the coolant flow to the heater/blower. But I don't know what to look for after checking the mono-valve. Maybe the climate control system/thermostat?
