Can anyone help me? I'm trying to hook up my heater that had been disconected. Someone just looped the hoses at the heater core. The only cable that I have conected now is the heat to defrost cable. I need to know where the heater cutoff valve is supposed to be and the temperature control valve. They are all cable operated (no vacuum) and I am pretty sure that thay are to be under the hood as there is no temperature control valve on the heater core. Can anyone help with location and or part numbers? Thanks for any help.
