could it be something with the vaccuum?

your vacuum switch that operates the control is malfunctioning, fairly common actually, its probably cracked or a vacuum hose is bad or has fallen off. the switch is behind the dash, connected to the knob that you use to control where the air blows.... good luck , not that much fun to get into on some vehicles.

The heater-A/C device airflow is controlled by using engine vacuum. If this vacuum source is misplaced (vacuum leak) then the device immediately will direct the airflow to the defrost vents by using default. so which you will could desire to ascertain that the device is receiving vacuum and that the unit that controls the vacuum distribution to the incredibly some vent flaps is working properly.

diesel engines don't produce vacuum so you have a belt driven vacuum pump. Start with the pump and make sure it's working then follow the vacuum hose to where ever you find the leak. Sorry I don't remember where the pump is on your engine I just know it's there.

Yes, you have lost vacuum to your control switch, coming out of the defroster is a typical sign of vacuum loss.........
