My AC died for the 3rd time this summer. Want to guess, HP hose or Compressor?

Yes battey was disconnected 1st

I would start at checking fuses. Possibly disconnect battery and try for another reset. Then you would probably need a scan at that point.

Going to to go and check the connections make sure we didn't miss 1 ,Forscan showed some modules not communicating next I'll connect my Accessport see what codes I get? he good news is The AC is working great!
Thanks!

Well, the connectors were all good going to connect up the Accessport clear the codes see what happens.

Here I go again. AC died yet again. Two things on this car I hate. The shitty AC and the damn Clutch sensor. Constant failures.

I honestly believe it's the heat generated by these engines, and the high rpm's the compressor's pulley spins at.
Have you ever looked at the inlet air temp if you're sitting in traffic on a hot day? Mine routinely hits 150°+. Then when you come home, all that heat is trapped under the hood. Something is sure to go. That's why whenever I come home after a spirited drive, I always turn off the car, and then open the hood so the engine bay can cool down. I had my battery tender connections on the battery start to melt/deform once, before I started opening the hood. That's how much heat is under the hood after a big drive. What do you think that heat does to all the a/c hose connectors and o-rings?

And you'd think the Mustang engineers at Ford would be aware of those conditions and test the components under that heat and pressure and ensure said components would hold up. The AC compressor in my 2016 at the time went out TWICE. I'm hoping the system in my '22 will fair better.

Every year I turn my air-conditioning on for the first time and keep my fingers crossed.

Every time I use the AC I cross my fingers as well.

Nine years and counting for me.

Hello; I have told the story of a guy for whom I did work on his cars for a few decades. He collected antique furniture and old cars. Trouble was he treated the cars same as he did the furniture. That being he let them sit around for years to decades. Fine for furniture but awful for cars.

To my point. Even the modern cars with AC also sat around sometimes for years. He had an interesting notion about insurance in that he only wanted two cars insured at any one time. So, the cars not insured sat for at least six months to a year or more. Among the other problems a sitting car has, one was AC problems.
My take from reading and his experience is the seals need to be lubricated regularly. I make it a point to run the AC a couple times a month all year. Not an issue since I do not park my vehicles. That keeps the seals lubed.
I admit this does not appear to apply to compressor failure. I do not quite see a connection. I wonder if the folks who drive a Mustang all year have the same level of AC failure as those who park them for many months???

Mine is loud AF when it is on and you increase RPMs. Works, but I imagine it is on its way out? I hardly ever use it, only when wife is in the car.

I have 79k miles on the clock and daily drive it all summer long.

Yep. Being through that as well. Just a matter of time. I would replace it before it goes down.

Will Ford touch it until it breaks? Been to dealers too many times that won’t do any work until so.

Another tip that (so far, fingers crossed) has proved worthy to me...do not replace with another Ford/Motorcraft brand compressor.

My dealership has. Two of them. One the mechanic heard it and had it replaced. The other I heard it and complained and the mechanic agreed. The other compressor just flat out broke.
