Question about 2000 Jeep Grand Cherokee
My air conditoner was working fine. Blowing cold. Then one day I was setting in a parking lot waiting for someone and I smelt someting burning so I turned the air off and the next day I went to turn it on and the air would not blow but I could here the compresser kick on.So my brothger in law checked to blower motor and he wiggled some wires and it started blowing agian but the only problem is that now it will only blow hot air. It feels like the heater is on even when i push the air conditioner button. The freeeon was checked and they said that it was full. Any ideas what is wrong?
You have a blend air system. this means that it uses both the a/c and heat to control the cab temp. there are doors that open and close using servo motors and chances are one or more of these motors might have shorted out. unfortunately they are under the dash and a pain to get to. i would advice that you take it to a shop and let a qualified tech replace them. it will save you alot of frustration in the long run

I also have a 2001 Cherokee w/ the same AC problem, except when the dealer tried to charge me $2000 for the blend door repair, and a head controller. i replaced the head controller myself from LKQ autoparts (national) for a third of the dealer's price of $600.
Try that first. The head controller is the whole ac control box in your dash, and is VERY easy to replace. Four screws to take it out, then unplug the wires and plug in the new one.
Blowing Cold for almost 3 months
