Hello and welcome to Just Answer. My name is Denny; now let me see if I can help you with your Jeep question.

There is a blend door inside the HVAC unit, that breaks, and causes this. You need to remove the entire dash, and then remove the HVAC unit, and disassemble to get to the broken door.

This is a big job, and quite difficult; I can send you some removal procedures, if you want to tackle this yourself.( if you want the instructions, you need to tell me if you have duel zone climate control or not.)

Customer: replied 4 years ago.
when you say dual what do you mean? My ac only has one knob to control the foot and the direct, etc. on the front and has vents between the driver and passenger that are to blowing hot air. And yes I'm mechanicaly incline. I will do it my self
Expert:  jeepmopar76 replied 4 years ago.
Duel zone, is for the Jeeps that have separate temp controls for driver and passenger.
Customer: replied 4 years ago.

do i have to disconect the evaporator to fix the blen doors? I thought i could leave the freon and oil intactc.

That all has to be disconnected from under the hood, as the HVAC has to come out and disassembled to gt to the doors.Sorry, but there is no way to do this with it still hooked up.
