I agree, these vehicles have a problem with the blend doors and since the accuators hit the door when it opens and closes, it breaks the doors. and it's a huge job to replace them.

You have the common 99/04 Jeep GC blend door problem.

A repair shop or dealer will charge around $1,000

There are do-it yourself blend door repairs on Ebay.

look for Main A/C relay, look for fuses, or go to a/c shop and have gas check out, perhaps leaks, perhaps evaporator, perhaps condenser, but start for relay box on front passengers side, or fuses on same side

sounds like the clutch field on or bearing on the front of the compressor went bad take a closer look at the pulley on the comp. and see if there is any debris or melted plastic coming out behind the pulley,if so the clutch,field and bearing should be replaced,hope this helps

If you have duel climate control, it sounds like the blend doors inside the heater box have broke. It is a rather large repair to do. If you don't have duel climate control, look for a broken, leaking or aged vacuum line under the battery try. Hope this helps.

Best of luck
