First problem - air conditioning

[HoosierDaddy]

So after two summers of malfunctioning ac and replacing the compressor and evaporator it turned out to be the damn pressure switch....a 10 minute repair.

Hey bud. Just thought I’d provide the diagnosis from Ford (took my baby in today). Evaporator Core....like I said. Have a nice night.

I hope your dealer is better at "guessing" what's wrong than smsgt350's was.

If you’re getting cold air on one side and warm on the other it’s is NOT the evaporator. It’s a blend Door actuator.
To replace an actuator the dash does not need to be removed. Whoever told you that if one side is colder than the other that the evaporator is bad is a dumbass.

My Mustang started cooling on the passenger side and warmer on the driver side. FOMOCO changed the evap coil assembly under warranty. The blend door and evap coil are all part of the same unit. BTW no need to be a dick.

My repair is coming up on 2 years. I’d say he “guessed” right. That’s what happens when you get a good mechanic. Like many professions, there are different levels of skill sets and troubleshooting abilities.

Mine can go a month and then suddenly, two hours from home, on a smokin hot day....hot humid air fills the car.

That sucks. There's certainly some issue that they haven't been able to find. I wonder if video evidence of a thermostat readout would help give them a kick in the butt?

nevermind - saw I responded to an old post..sometimes old ones look new again on here.

Mine had done this three different times last summer. One entire weekend while I was away at a golf tournament, I scheduled service ASAP at dealer and go figure it starts blowing ice cold before I could get it in. They replaced a temp sensor or something. Two weeks later we had it at a Mustang rally and it failed again on a Saturday night through Sunday and finally kicked on during our 4 hour drive home that night. Again, couldn't replicate at dealer two days later. Just 4 days later it did it on a 4 hour drive to a golf tournament, I shut off air for about 20 minutes, rolled down windows and restarted it, and it worked again. I've had the dealer look at it twice and never fails, it won't do it when I have the appointment, or it happens when I'm no where near a dealer or it's a Sunday when they're closed. Just blows warm air out. It was cooler to just drop the windows and let hot air in as it drives.

I've owned lots of S550s already, this is the only one that ever gave me trouble. Will see how it goes this year with the seasons getting warmer again.

There are two recent class action lawsuits against GM for premature A/C failure. I scanned a 60 page filing in one of these. It alleges faulty design and manufacturing. It points out that GM has acknowledged such in a TSB and also makes the point that the A/C system is also the defog and defrost system which raises a safety concern. These have traction because it involves GM trucks and SUVs, which far outnumber Mustangs. Also the issue was publicized in the media. I am not aware of the current status. While some have said that a class action is waste of time, i can vouch that they are not. I took a 10 year old Toyota Avalon with over 100K in for service and was told I had a free dash replacement due. I did not recall there was a recall and had not noticed a foot-long hairline crack in the vinyl. Under pressure of a lawsuits and bad PR, Toyota agreed to extend the warranty on models going back 12 years, fix any cracking, melting dashboards with no cost to the owner and reimburse anyone with a receipt for repairs already made. Was it a safety issue? Apparently they were not forced by NHTSA even though some complaints were about the melting dashes causing blinding glare. I suspect it was more about the Toyota image and their eventual acknowledgement that the vinyl was in fact defective. (You can research it or if i still have my recall letter I can post it.) I also suspect Ford would likewise agree to at least an additional 12,000 mile 12 month extension of warranty a likley at 24/24 with reimbursement to anyone who paid out of pocket within that period. Not only did they put an admitted defective part in the ponys, they put them in an inaccessible place because they expected them to last like the industry standards. And they really do not want media pictures of a 2016, 10,000 mile Mustang stripped down to fix a defective evap coil - for the second time. My distant Daughter has a 2016 V6, over 36 months with just 15,000 miles. she just told me the A/C is blowing nothing but warm air. I know not what course others may take, but as for me . . . I might just know a starting point.
