My 2014 Durango SXT V6 3.6 is currently in the shop (April 2025) for a front A/C issue—it randomly stops blowing. The issue started late summer 2024. Pulling the green 40A fuse under the hood helped a few times but didn’t last. I finally gave up this week and went in, paid $80 for a diagnostic, and the mechanic recommended replacing the 40A fuse, relay, resistor, badly clogged cabin filter, and blower motor—OEM parts only. I picked it up on Day 4 and the shop was confident it was fixed… but an hour later the A/C stopped blowing again, so I took it right back. It’ll end up being a total of 7 days at the shop. They found a short under the fusebox in the harness that plugs into it. I went to the junkyard, bought a fusebox, and they’ll be fixing the shorted wire in the harness and reinstalling the fusebox. All of this cost me $850 (labor included). I still don’t know what caused all of this, but I’m crossing my fingers that we’re finally at the finish line. Can someone please tell me what caused all of this? Because without fixing the short and replacing the fusebox, you’ll keep running in circles burning out the resistor—until you change the fusebox and fix the short. But what caused the short to begin with?
