ABILITY TO REPAIR FAULTS

<p>Hi</p> <p>I have a 2012 jeep grand Cherokee overland crd with extended maintenance plan. For the last year I am hoping to get a very annoying noise fixed in the cabin. It is a noise that apparently jeep knows where it is coming from, but not able to fix. Had my vehicle in on several occasions. They say it is the air con unit.</p> <p>How do I get this repaired</p>
