Fan blower direction **** not working stuck in defrost
My **** that sets direction of heater/air blow direction isn't working just blows in defrost setting at the windshield.

The controls are vacuum operated and default to defrost for safety reasons when the controls lose vacuum. Look for a vacuum leak, starting with the reservoir behind the front bumper

When I was putting on my new bumper I rerouted that thing and ended up breaking the hose, and I still haven't replaced it yet, and I have the same problem. Maybe your hose broke or was held together with electrical tape or something...
