Could you please tell me if a 1997 Chevy Venture has a heater control valve and if possible the location of the valve.
Look near or behind the alternator. The valve that controls flow of coolant to the heater core on my 1987 Aerostar is located on the left wall of the engine compartment. I imagine the 1991 is similar. Trace the heater hoses from the engine/water pump and you will find it.
You don't have a heater control valve for this truck.......
