Typical issue is a vacuum leak. The actuators that control where the air is directed (floor, panel or defrost) are "powered" by vacuum. It is common for the default (no vacuum) configuration to be the defrost setting.
You should have a vacuum line going into the firewall from the engine compartment. I would check that first.
