I have a 2000 with 4.0. 4 door 4x4 automatic. When my Jeep is first started & cool the ac works fine. But after it warms up or I stop at a store for a moment and shut it off and restart it, it doesn't work. The fan doesn't work, I can feel cool air wanting to come through the vents. It also just stops while I'm going down the road sometimes. Any help would be awesome. Thanks. Let me know if you need more info or I'm leaving something out. Even if I turn the **** to vent or whatever the fan won't push.

 

Is the blower motor coming on at all. If so, Check your blend door to see if it isn't sticking.

 

Sounds like loose connection or motors going out .Check for current at blower motor plug next time it quits .

 

Yep. Doesn't make since for the motor to randomly stop other than a bad connection or motor itself is dying.
