Heater blows only from the front. When you try to change over to defrost, it still blows in the front vents. It will not change to blow in the floor either. Is there a fuse problem or a switch problem? And how do I fix this?

You can try to reset all the system by disconnecting both battery terminal clamps and touching both battery terminals together for 5mins to clear out all memory. NOTE doing this will clear all memory (ie auto down power windows, radio presets, clock ect). If this works for awhile or not at all then you probably have an issue with the small motor that controls a door in the air condition system behind the dash. This door directs air flow out the defrost, front vents, or floor vents. Sometimes when these motors go out there is a clicking noise when adjusting the air flow or turning off the engine. If it is a motor, replacement is the only repair.

What is this small motor called. I have searched all different ways. And can't find the right name for this motor. Cause i'm sure that is the problem.

It's call a mode door actuator and if the a/c system has dual climate control then it would be the side the air flow is not changing driver side or passenger side.
