Usualy the units which were controlled by cable and vacum , today are controlled by mini electric motors should one of them fail they stay either shut or opne causing the problem the first thing to do is run a diagnostic check using a scanner

There are 2 seperate zones for the drivers and pass. side, but they use the same thermostat.
There is a blend air door motor that controls this.
The one on the pass. side is probably bad.
These are kind of hard to replace.
There are on the bottom of the heater box and you need a philips screwdriver about an inch in total length.
There is not that much room between the bottom of the heater housing and the floor.

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.

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.

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

Check the coolant level, sounds like you may be slightly low....Be sure heater is on high when filling the system....Look for any air bleeds...
