i can hear the ac working but the air is not coming trough the vents inside anymore
there should be a cable to change the air doors...perhaps nowadays there isn't a cable anymore but a series of servo motors...these would be fused and/or have a relay...check the fuse and relay for this function...wish I could tell you more....will give it more time, later...thanks~
is it blowing through the defrost vents? if it is, you have a vacuum leak. go to jeepforum.com and use the search on there and it will give you ways to check and lots of info
If there is a vacuum leak, recommend replacing those hoses with silicone hoses like BMW and the cop cars use~
recirc door has broke and is covering fan. Remove blower motor and remove broke door.
