I answered this question just a few prior, but you have a vacuum hose leak. The defroster vent is the "default" setting when this occurs. Open your engine hood, look slightly left of center up along the firewall. There is a really tiny black hose coming from within the firewall that "Ts" into another hose. It's hopefully broken where visible. Use a piece of tubing like a splice and fit the original ends into each end of the new piece. If it's broken on the other side of the firewall, the entire dashboard will have to be pulled. And I've both read and been told that's not a job for mere mortals to tackle. But take your time and look around. And be gentle 'cuz you don't want to screw up this very tiny piece of tubing. Good luck.

Why would the air conditioning only blow air from the defrost and floor vents and not the dash vents?
I would think that is a vacuum or a linkage problem with the heater control assembly (where all the buttons/slides are for changing between floor/defrost/vent) Had a diaphragm go bad on one once, and in a jeep cherokee, a slight collision with a guard rail knocked a vac line off for the vent controls, and ac only worked from defroster.
Why is your air conditioner in your 2004 jeep grand Cherokee blowing out the defrost only?
Vacuum leak in one of the hoses I own a Jeep Cherokee Sport, found that a broken vacuum hose was the culprit. When there is a vacuum leak, the blower-ventilation defaults to blowing through the defrost vents. Once the vacuum lines are fixed, the other ventilation doors are able to function and open. Your set-up and placement of your lines may be different, but mine were located in the front-lower right of the engine compartment, running up the right side and ending in the back/firewall. The lines are cheap and easy to replace, took about 5 minutes and 3 dollars!

How do i fix my 1997 jeep defrost vent All the other functions work but i cannot get the air to come out my windshield defrost vent.?
The acturators that control the defrost and vents often become inopterave because the mechanical link from the acturator to the divertors breaks. You can see if this is the porblem by looking just to the right and above the gas pedel. I have just tryed adding a screw and some glue to see if that works. The only problem is, that I had to remove the entire dash to get to the diverters and acturators. About 4 hours so far. But I am a shade tree machamic.
