Its usually on the passenger side fire wall or just in front of it between engine and/or just below the heater core hoses where the pass threw the firewall, it has the heater hose running to it.

Not on this one.chilton shows a typical ford old school valve.this had a t shaped plastic valve with a 3 prong plug in wire connection interior controls have heat ac and auto setting

Temperature blend door is stuck, either mechanically or the actuator, have the codes read by someone who can read B C and U codes. Generic scan tool can't do this! The door is inside the plenum under the dash, NO VALVE!!

That is 1998 and on? you didn't specify a year?
