I have a 2013 Jeep about 132k miles and my AC stopped working unexpectedly in july. It turns on but only blows hot air. I’ve tried refilling the ac but it wouldn’t go in if that makes sense. It’s as if the lines were clogged. I’d like to know what it could be before I take it in and pay to get it diagnosed or if it’s something I can have a family member fix at home.
