You probably have a vacuum leak on the passenger side. its a small plastic hose some times they come unpluged from the engine. or brake.

Sounds like your temperature actuator is not moving or your temp door is broken. On max a-c ,coolant is shut off to your heater core allowing only cold air in.

Check the vaccum line at the vacuum distribution block (to the right of the brake master cylinder). It's the smallest vacuum hose.

AC is only blowing through the defrost vents in the dashboard?
I think your problem is the head unit that selects where the air comes out ie. Face, floor, defrost, or hi-level face and floor. If that's not working then it will not let you switch location that you want the air to come out.

Air blowing out floor and defrost vents but not not front vents
Sounds like a blend door problem. The vacuum from the engine opens and closes the door that directs air flow thru the vents.
I would guess the door is stuck in the middle of the range or something is blocking it.
The blend door(s) is behind the glove box.

The ac only blows in the front thru the defrost vents. blows cold
there is most likely a vacuum leak or a hose off somewhere. The air will default to defrost if there is no vacuum

Jeep AC blows cold air at defrost and feet but not through vents
There is a flap that directs the air. the flap is controlled by a vacuum actuator. This is located inside the venting. The actuator is connected to little vacuum hoses that attach to the temperature control switch. Either the flap is stuck, or the actuator has gone bad.

No heat - ac stays on blowing through defrost vents
If you have the heater directed to the windshield, the AC will turn on. Move the control away from defrost.
