You won't like this but... I have a 1999 Limited with the dual electronic climate controls like you. Apparently the way the blend boxes are designed, the motors are too strong for the plastic knobs that move the doors, so they simply break. Mopar has since made a replacement blend box and recirculate box (I guess that hasn't broken yet on you), that are strong enough not to break when the door flaps reach their limits. The computer control can sense when there is motor resistance, and that's part of the bad design. If you do replace the right/left blend air box, you should replace the recirculate air box at the same time. The labor is high, because they pour the entire Jeep around those two boxes when they build it - actually, the entire dash to the firewall must come out to replace these two boxes. I found both boxes on eBay for about $80 each, and labor at a local 76 station was $650 (beat the $900 & $1,200 estimates at two other repair shops). Recirc and hot/cold have been working great on both sides since. Check out www.wjjeeps.com for good information on your Jeep!

If there is warm air coming from one vent and chilly from yet another, I dont see the way it is linked with a Thermostat or coolant ranges, simply by fact the nice and comfortable air could be coming from the heater middle. If it became the thermostat being caught open, then not one of the air might get heat. Sounds greater like a diverter, interior the ducting of a few kind, no longer commencing to the right place.

Could be you do not have strong enough anti freeze, you may have ice in your heater hoses keeping hot water from reaching your heat exchanger. Also you may have ice keeping water from going to and from your radiator?
If that is not the trouble, look at your thermostat, it could be stuck closed, but then your heater should work if that were the problem. Most likley its ice.

if its blowing hot on one side and cold on the other one its a vent door stuck closed on it,,if all your getting is cold air ,then you need to check and see that the coolant is all the way full,if they get a little low,,they may do this,, if it was working,,and stopped ,id check the coolant first,,it may just be low,,other wise you may need to check around the heater box,and make sure all the lines and cables are on ,,that make the vent door open on it,,and check the thermostat also ,good luck i hope this help,s.

Blend door could be broken or stuck, also check actuators or vaccum lines and heater core, heater hoses ect.. Before taking dash out.

I'm not a mechanic, but my first guess would be that there's a door in the ventilation system that controls how air gets distributed, and that the door mechanism has failed. I have no idea how you would get to it to fix it, though.
