air won't switch to defrost on 1998 Toyota Camry

The air now blows out the front vents but it won't switch to defrost.I removed the controls they seem to be working correctly. How do i figure out what the problem is? What actually changes the air from defrost to forward to feet? How can i fix it?

It sounds like your blend door is not functioning, that is the door that directs the air from your feet to the vent to the defrost.
