I think you just found your problem! The hot water valve should be located right behind the engine - there are three hoses that go it and one vacuum line. If it is OEM it is probably really rusty by now. If you have no hot water valve, then hot coolant is going to your heater core, which is warming the cold air from the A/C. Good detective work by your shop! Sometimes on here we forget to take into account the dreaded PO 'repairs' that may have altered your car from stock. Andy In a message dated 6/22/2006 3:35:21 P.M.

They went to looking and found out that I don't have a hot water valve at all. Its completely gone.
