I’m not convinced there’s anything wrong with my compressor yet. I’ve had several of these minor issues in past superdutys. I had a 2015 that did it once going down the road, just kinda got warm, then cleared up. Took that truck to 150k miles. I had a 2022 that did it a few times also and took it to 150k miles also. But these were wile driving. This episode with the 2024 was wile sitting eating lunch. Has been ice cold and normal for the last 2000 miles since then. I do not think there is anything a dealer will do at the point. It works great. Might have been a glitch with sensor and froze…who knows. Still got 9000 miles of warranty, i usually get the esp, this issue may force me to go ahead.

I missed my service appointment last week and had to reschedule for Sept 22. I’m at 28000 now. Blew 84f twice today. Service guy said worst part is that they have to wait for ford to be ready cause they basically hook truck up and send real time data to them, and they want it a couple different ways. I also opened a customer service ticket, and am supposed to call the day before I take it to activate the ticket. Service guy said maybe it can help on fords end to be quick. He just had one truck waiting 2 months for an ac rebuild I think he said, I kinda drifted, and had one take 2 days for ford to get to the diagnostics.
Grasping for straws….anything to keep down time at a minimum. I haven’t drove anything except a ford diesel pickup since 1997, and have had only 1 transmission and 1 radiator replaced in 13 trucks and over 1 million miles. Some minor stuff but no major downtime.
oooooh, that helpless feeling you get when you’re at the mercy of the service department and ford. lol.. I live in this thing 3-4 hours a day.

I just don't get it. All the gizmos on these truck these days, most I don't give a ***** about, but A/C is one of the most basic features of any vehicle, maybe in the top 3 of things that should work on all vehicles for life. You pay $80 - $100K or more more for a truck and the A/C craps out in just a few miles? Pretty poor.

Add one more compressor failure to the list, mine. Just diagnosed today. The good news is there were 232 of them in Denver and there is actually some sort of recall on them.
Next week appointment to replace and charge. The service tech said this was the second one this week in a small town dealership of 8000 pop.

Well, you can add mine to the list. AC stopped working on the way home, 24,200 miles. Blowing ambient just as I entered the slow zone on my daily route, got back up to highway, kicked back on, then quit at the next stop and bew ambient the rest of the way home. Popped the hood open, compressor clutch is engaged but not moving refrigerant.
2024 F350 DRW Lariat, build date 03/24
They performed that TSB or whatever it is called to check the compressor about 6 months ago, said it was fine, but sure as schittnit, its failed.

If the compressor is spinning and no refrigerant is flowing to drop the temps, then there is an issue with the compressor. These systems are not that complicated really, the electronics that regulate temps in the cabin can be a PITA. When Refrigerant is flowing it expands in the expansion valve, soaking up heat through the evaporator, then gets sucked up by the compressor and turned into a liquid via the Condenser where the heat is removed repeating the cycle. Pressure switches signal low refrigerant and stop the compressor as well as high pressure signals to shut it off. If there is a blockage, there will be a variance in the switches to disable the compressor. If just enough is flowing to keep pressure in range, the compressor will still run.
Since its still running its producing just enough flow to keep the low side from dropping, but not enough to cool with. The temp difference between the low and high is ambient which means its just barely flowing. I wish it was an electronic glitch that is easy to reset, but not in this case, the compressor is turning, no refrigerant is flowing.

Are you not familiar with these new variable flow compressors?
you don’t have a clutch anymore to my understanding, just a pulley. The flow is controlled by modules, or the ecu.
so yea, these systems are now complicated.

From what I can see of it, the one in my truck is still using a clutch. Regardless, if flow is regulated by an ECU, the principal remains the same. If the compressor is spinning and not pushing refrigerant, the compressor is not doing it's job.

Im not happy with this new change. I’m good with working on traditional compressors. Instead of a set guages now you need a computer to diagnose a compressor.
