the directional for defrost and dash panel may have gone bad,there is no fuse for this. under the dash on the main vent,you will see a little box/with an electrical plug in. it's called an acuator.when you turn the knob to defrost,or dash,the acuator turns the door on the main vent to let the air flow to either the defrost,or dash.your acuator is most likely your problem.there is only one plug in to it and only 2-3 screws that remove it frome the vent panel under the dash.thank you for choosing fixya.com!

I have no defrost on my 2001 montana van, works ok on vent, but not as well on heat


Take the cover from under the steering wheel off and look up inside there where the motors and levers are that change the flow of air. I've worked on many of these and they seem to bind up from one position to another. Watch it move as you turn the knob from defrost to vent to floor. It may just need a little lube.

Heater knob will not turn to defrost and stay, air blows only from the console vents, if you try to turn the heater know to defrost it pops right back to the console vent


GO UNDER THE DASH AND REPLACE THE CABLE, THAT IS BENT. YOU DON'T HAVE TO TAKE OFF THE DASH PAD. ALSO CHECK THE FLAP TO SEE IF ANYTHING IS IN IT CAUSING THE CABLE TO BEND.

If I am reading correctly you are hearing the vent doors moving to redirect the airflow to the vents you choose. This is normal and can be more noticeable if the blower fan is on, putting air pressure against the doors.

The knob has vacuum hose that is attached to an acutator that moves the flap inside the venting controlling the direction of the air flow. The vent can get stuck, or the acutator can become leaky and faulty.
