Hello khankinsirwin:
 
Your symptoms sound like the common blend door problem.
First thing is you should check the HVAC system fault codes.
 
The cost can range from a DIY job of $20 to a repair shop cost of $1,800
 Of course the cost depends on what is wrong with the system.
 
Also if you cut an access hole to check the blend doors and rear actuator motor (The actuator motor between the firewall and the HVAC box)
 
And you find that the rear actuator motor is not working.
That does not mean the actuator motor is bad.
 
Usually what happens is the computer will shutoff an actuator motor that makes one revolution without any resistance.
 
That actuator motor could still be in good working condition.
 
Post a message, if you need more information and on how to check the rear actuator motor.

#510 of 511 Heater blend doors ! by mrsixpack

Ok, so do not take your GC to the dealer to get the doors fixed, they want $1550 to fix mine, they just check the codes and say everything needs replaced but I can see the dang motor turn so they are way off on their repair guesses ! Check out the NAGCA.com site and do lots of web searchs, I just got the parts to fix mine for $70 ! It replaces the cheap plastic doors with metal doors and a metal rod, You cut into the heater behind the glove box....no need to remove the dash ! It makes both sides work off the drivers heat controler but its much cheaper then $1550 and in shop for 2-3 days.....you can do it at home in a few hours...well maybe a day if you really want to be carefull ! One sites said the hardest part of the repair is clean up after your done !
One more thing....I took my 01 GC to the dealer to get service, they checked off the "checked battery and cables" I came home and was looking under the hood and the battery cable came off in my hand, I went to the dealer and yelled, even went and found the owner and they both said they just look to see if battery is there and not covered with corrosion....they did not touch the battery or the cable ! No checking of water or to see if it was secure or anything...they just look to see if its there !!!! I guess they did check the tire pressure as all 4 air valve dust caps are missing ! Never take the dealer shops or any shops word on what they did...check everything yourself ! Love my Jeep GC but hate the dealers and their shops !

Trying to troubleshoot A/C in 95 Jeep grand Cherokee. Everything seems to be working, freon pressure good, I can hear the compressor engaging, and the blower works fine. Just no cold air. What should I troubleshoot next? FYI, this is an older Jeep with very high miles.
