usually the engine relay or cooling fan relay..!

Could be the switch that controls the fan or the fan its self. Possibly a fuse has blown. All are a fairly easy fix

hi
there is no recall from jeep (there should be) your blend doors are damaged or broken. jeep will quote you around £800 to fix. log on to heatertreater.net they have a diy quick fix that will last the life of jeep. you can install the new blend doors that are metel (not stupid plastic ones jeep use) in around half an hour, this really does work as i have installed a few of these kits with no problems.
hope this helps

sounds like system is low on freon,? safety switch turns system off when too low on freon to prevent burning itself (the compressor) up...
