Could be a problem with the vacuum supply to the blend door. However, you'd probably get better answers in the 1997 - 2003 forum which is a couple of forums down the page.

And welcome to

Sounds like a possible broken blend door. Do you have manual heater controls or EATC? Good luck!

EATC I talked to a Ford tech today . He seemed to think maybe a pencil or somthing got down in there and won't allow the door to work . He said if it is broken I have to pull steering column and dash out to fix it
