a/c blend door problems, need help

I just got my 2000gc limited back on the road yesterday (spun rod bearings) and everything was fine until tonight. I had the jeep idling and all of a sudden the passenger side vents start blowing out really hot air. Driver side was fine and the a/c stayed cold but I cant get the passenger side to stop with the hot air. I also live in South Carolina so its like 110 degrees or so and I cant get the heat to cut off so any help will be greatly appreciated.

How many miles are on your WJ and have you ever replaced the HVAC blend doors? Sounds like you are about to spend some quality time with your jeep replacing them if you have dual climate control. Been there... done that!

I used the "blen dor" kit, find it on ebay. It seems really well made and simple to intall. Tape over the passenger side outlets for now to keep cool until you can fix it.

Had the same problem on my wifes 2000 Jeep. Go to Blendorstore.com and buy the kit for $135 and you'll fix your problem. Go ahead and get the recirc door for $45 while you're doing it. I won't lie, it sucks taking out the dash and probably even more putting it back together again. You're gonna need to get the A/C drained obviously. You can do this all yourself or pay an extra$800-$1,000 to have the dealer do it. You tube grand cherokee dash removal, it might help.

Mine acts that way sometimes even though I've replaced the blend doors, actuator and head unit. Particularly after I've disconnected the battery for some reason. Try initializing a recalibration of the doors.
