Thanks for the picture. Since the monovalve defaults to open if it has failed and the aux water pump just circulates the coolant, then whats next?

Climate control unit? The AC works great I get a really stronge flow of cold air, so I know part of the climate control unit works.

My symtoms are: if I turn on the heater to full, I get warm air for about 20 seconds, then it turns to regular. I think this may be warm air that is just trapped in the system, because it only does this after the heater has been stated once. If you turn it off then back on agian you get just regular non warm air..

I do get some slight condensation around the windows after engaging the heater as well. I guess since I should never be getting condensation perhaps the heater core has developed somekind of leak?
