Where is the heater control valve on a 1993 E-150 Econoline conversion van? The van has front and rear heaters and A/C. It is an Explorer Van conversion. The truck has a 351 Cubic inch V-8.

hello there,
The heater control valve for the rear air is usually located right behind the drv seat area but underneath the van. [laying outside on the ground, underneath the van] If you do not see it there follow hoses the whole lenght that you can see.
The front system should not have one.
