wheres the blend door valve?

[steve63]

getting ready to replace the blend door valve on my 90 ranger,only getting partial heat,ruled out the heater core as its flowing well,where is the blend door valve?

It could be the cable from the control panel. When you slide the lever, it should move the cable. It could have come loose or as you mentioned the door itself. I'd pull the control away and check the cable.
