Changed dealers to check my A/C. They actually troubleshot and found metal in the system left by the previous system.

*original dealership said they flushed by hand manually without some tool that was on back order. Long story short the dealership replaced the compressor and flushed the system but never touched the evap well enough*

the new dealership is replacing 100% of the A/C system. If you have the A/C issue I would make sure they flush the evap well. That goes for all A/C system on a car, home or fridge etc. I’ll have a new list of what was done to it soon to post.

Issues I had and the reason I brought it in the 2nd time was the A/C being on low fan speed and LO temp blowing at around 45F. When you raise the fan speed to high and kept the temp set to LO the temp coming out the vent would be between 73-77F. The first dealership that did the original service and repair said as long as the temp is 20 degrees cooler than outside the A/C is considered satisfactory. So when it’s 97 outside and my temp was 75 out the vent they brushed it off. Do not accept that answer and do not settle. Reference me and I will give you my case number and info as proof. It is absolutely rubbish that some NOT ALL dealerships will not look deeper into a known issue. I’d expect a recall coming. Second dealership said they do a lot weekly and immediately told me about the issue. Find a service department that is competent and cares about their customers.

 

Yeah, I did some research on this. Its a flow regulator that will either allow full flow of the pressure, or redirect it back into the compressor. Sort of like the flow regulator on the CP4. Of course I have an appointment with a loaner and the damned AC worked perfectly yesterday and this morning.

Anyone know if it stores codes when it malfunctions? I would look, but I don't want to upset the ODBII in case there are.

 

from what gather there are a couple of guys here that took theirs in because of issues like ours but ac passed test, I don’t think there are any “codes” to be read. I have an appointment Monday and my ac is freezing cold.

 

None of this makes me super confident in taking my new to me, 2024 F350 towing across the country next year....

 

Well, as it always is, the day after it acted up and ever since its been fine, so I canceled the appointment since, no, there are no codes set, and even if there were, after 10 drive cycles, they would have been purged.

 

I’m headed this morning to get mine tested. There are no codes, but there is a long test they do at multiple rpms they perform. This ac is so aggravating. Coming home Friday at 90f it went warm in the interstate. Turned off and it was fine for the rest of the 50 mile trip. Its probably done this 8 or so time now.

i have a call in with customer service so maybe it helps with the the techs communication with ford since the tech only performs the procedure and sends data to ford to be reviewed. If it comes back clean i will lose my crap then and there with ford, not the service guys as they dont make the call on this one. Too many of us here dealing with this and a couple guys here were turned away be cause the test passed fords criteria. But most of all, I”M INCONVENIENCED AND TAKING OFF WORK TO SIT AT A DEALERSHIP….lol.
realistically I’m bringing a couple p365’s i dislike to trade in next door at the gun shop for the smith shield plus, and probably going to walk to harbor freight and walmart. Make the best of it.

 

How my appointment went. They hooked to it and ran the different tests…ac ran cold and good. Asked a couple more specifics and said they would idle it some more. I packed a backpack and walked to different stores during this….lol, but when i got back the service manager was in passenger seat and a tech was driving and they just pulled in. I got in the back seat, service manager had his laptop in his lap, they tried everything to get it to act up. Showed me everything. Ford will not approve a new compressor unless readings show an issue. I pass them(dealer) on my long commute and they said if it starts to act up just pull in, dont shut it off and dont restart ac, they will hook to it quickly to record. I do about 800-900 miles a week and am at 29500 now. We are going to start cooling off rapidly. I’ll be out of warranty in about 2 months or sooner.

currently pricing esp’s…. $4200 for a 175k miles and 4 years for the one that covers 113 things..1000 things is $5500, base is $3600. All cover ac….13 superdutys since 1997(first was the osb) and have never thought once about an ac issue. Probably well over 1 million miles. Then ford decides to “upgrade” the compressor style and now it’s a thing. Disposable variable compressors to help meet epa standards on economy across multiple models. Poop.

 

Yeah, so many tech items and the co4 to go bad. I bought an ESP plan from Granger shortly after taking delivery.

 

I’ve had them on my last 3 trucks(get a new every 3 years) and never used them. That’s like $12k of thrown away money.

wonder what a complete ac system costs? Compressor, evaporator, condenser? Worst case scenario.

 

This is insane that Ford hasn't been able to fix this A/C issue since they've known about since 2024. Here we are almost through a 2nd year of this issue and nothing seems to have been fixed. New 2025's still encountering the same issue. So, what about the 26's?

 

I wonder percentage wise, what percent of failure? Will Ford recognize the problem and grant extra warranty? Perhaps if enough people have problems a class action lawsuit? The small Ford dealership I was at, has only done 3 counting mine. I have never heard what actually fails in the compressor. If it is a faulty solenoid or what?
2 separate wiring connections. 1 for the electric clutch and 1 to the solenoid that changes the angle of the swash plate which controls the length of stroke of the pistons.

 

I didn’t get into numbers but they just said most of the ones they replaced were on f150’s, and it was sometimes a long drawn out process to get it covered.

 

so I’m approaching 32000 miles and the temps are changing, i will be out of warranty in about 5 weeks, but still less than a year old. By next summer when ac is used hard again ill be screwed, screwed either way because I’m about to spend $4k plus on a warranty but at least that will cover other stuff for the next 175k.

ac has worked well, but is weird. Sometimes you think its just ok, then other times it is so cold your set at 74f in 90f which historically I’m always at about 68f in all my other trucks. Yesterday was really aggravating, it was about 80f, a coolish 80f, but it was just wanting to blow cold meaning i had to take it to high to get heat to come out. It’s like it was only on ac mode, until you cranked heat way up. The ac button stays lit in auto. I’m starting to wonder if there isnt a blending issue, even off of auto it still acted weird. I know I’m being hyper critical but its just not acting right.

 

Is it still an issue? The affected dates were 1/2/2024 - 6/10/2024. I've been intermittently following this thread and it seems like that was it. The few having problems outside of that window are likely just usual manufacture defects from various causes.

 

My Build date was 3/2025 and my A/c failed at 4000 miles. Still an ongoing problem.
