Where is the heater control valve located on your 1994 e 150 van?

On a 1994 E-150 van, the heater control valve is typically located near the firewall, on the passenger side of the engine compartment. It is connected to the heater hoses that run from the engine to the heater core. You may need to remove some components or panels for better access, as it can be somewhat hidden behind the engine or other parts. Always refer to the vehicle’s service manual for specific guidance on locating and servicing the heater control valve.
