Could be a problem like mine. I have my heater box out right now and all I can find is a bad recirculate blend door. From what I gather jeep Grand Cherokee is bad for blend door breakage. good luck

Check your resister pack, if the air is still cold then the freon is being moved by your compressor and passing through your orfice tube fine so there is the right amount. DO NOT open the system unless you have to, each time it is open they sugggest a dryer/reciecver replacement. The resister pack is a small block about the size of a palm of a hand. It contians a set of coils which conduct electricity at different rates based on that rate <the amount of voltage> your a/c fan will blow that speed. For example high= no resistance, low= 3 reiester if you have 4 settings

Why does My thermostat Not switch between ac,heat,defrost . there's cold air coming out of vents but not cold enough to be ac. Initially when this started the ac was blowing hot air
If the air flow cannot be controlled from vent/defrost/floor you may have a blend door issue. This is an electric motor that operates a door in the heating system to control airflow. There are usually 3 motors controlling airflow direction,heat and recirculation. The Ac not blowing cold may also be another problem. If the AC is operational, the compressor will be engaged and the Ac low pressure line under the hood will bw cold. If this is all ok then a blend door issue should be suspected

2000 jeep grand cherokee, only blow out a little air even when the blower on hi,,you have to put your hand next to the vent to feel the air
you may have had something fall down into the defrost vent and it has worked its way down and is blocking the air flow thats trying to come out the vents,near the blower motor.also does it sound like the blower motor is spinning on high speed or at a lower speed,you could have a slow turning blower motor.

I have a 2000 jeep cherokee sport 6 cyl. The a.c will come on and blow cold air for about 5 min. then starts to blow hot. Can't get it to stay cold. What could this be?
over pressure or high pressure in system will cause high pressure cutoff switch to go open,also poor air flow across condenser could add to the problem. When the A\C stops getting cold is the compressor still engaged and running.

2003 Jeep Cherokee (Liberty) air con
You most likely have a problem with a part called the air temperature control blend door, it controls the air flow across the AC core or heater core, it is most likely warped or the motor that operates it is defective or in most cases both are in need of replacing. This repair requires the entire dash be removed to access the AC parts.

Heater ac blower inop and only cold air blows on passenger side.
The blower problem on your jeep needs proper diagnosis. This could be one of several problems.
As simple as a relay or as big as a blower motor. With automatic temperature control you could be looking at a control assembly.

the cold air on the passenger side is a passenger blend door problem. Could be the actuator or a broken door. This problem requires removal of the entire dash to get to the problem. Not something you want to tackle without a complete step by step set of instructions.

I do have one other suggestion for this problem. You will still have to get the blower problem to complete the repair. Copy this link and go see what you think about blend door repair.

96 Jeep Grand Cherokee will not blow out hot air
It's possible you are not getting enough coolant flow to your heater core. Try pulling the hoses off the core, blowing it out with air compressor, fill with water and blow out again. Try this about five times and see what happens. Alot of times these cores will plug up or have restricted flow. They will blow warm at low speed but it won't flow enough hot coolant through to stay hot on high blower speed.
