Default 2004 1500 defrost not working

I get good heat and air but it won't defrost for ****. How should I go about figuring out what's wrong?

It could possible be the actuator motor but if that isnt it I'm not sure what else it could be.

Start with checking the blower motor, and the blower motor resistor. I do however suspect that it may be an issue with the blend doors.

Have you checked to see if you are actually getting air out of the defroster vents?
