where is the heater control valve
Like most cars. The heater control valve is located inside the closed compartment with the heater core and the and the AC condenser. It is a door flap that seperates the heated air from the outside air, or the AC air.
On top of the accumulator/drier (It's the cylinder on the passenger side of the engine not too far from your heater fan) It has a plastic cap covering the valve.
