blend door actuator could have failed,also check vacuum lines down by gas pedal make sure you didn't kick them off.

Defrost is the "default/safety" setting for the HVAC. Your blend doors have to be powered to a vent or floor setting. You might also wanna check the 1way valve on the passenger side of the intake where the HVAC n cruise vacuum lines tap into the intake. If the 1way valve goes bad, the HVAC will default to the defrost, however, usually only on acceleration tho.
