Cold air not working on Driver-side, but works on Passenger.

Just got word - no leaks, but the compressor clutch won't disengage. Thankfully they can replace the clutch itself and certainly a lot cheaper than the EVAP coil.

Interesting. I’d love to hear how this would affect cold across the dash left to right. Hopefully you don’t end up with two separate issues

I asked that very question but didn't get much of an explanation from the service manager, but since I have to leave it overnight to fix the trunk wiring recall, I'll call in the morning to see if I they can give be more info on what led them to the conclusion.

As I mentioned previously, they didn't find a leak when I asked so....

Just watch those shady mofo’s. Compressor clutch being stuck in means nothing more (to me) than the a/c running continuously, meaning always on and pumping refrigerant Good luck, come back with updates!

Unless I misheard (or he misexplained) and the compressor clutch never engages. Guess I'll get that tomorrow.

Yes sir, see how it plays out. If the compressor clutch has an issue, it needs to be adressed regsrdless

AC is working. Seems to me its just a damper for.drovers side.

Does.it work on the window.and floor?

the compressor clutch never engages.

Hello; Not sure how the AC compressor clutch works on newer cars. On older AC units it was engaged by way of an electromagnetic plate. Electric current creates a magnet which engages the AC compressor to the spinning pulley so that the compressor spins.

I await a final call as I am still confused on one main point mentioned a few times during the thread. Both quotes above should not be correct. Ought to be one or the other.
If it is that the clutch will not engage such would explain why an AC will not blow cold.
If the clutch stays engaged all the time then the compressor is spinning and you should get cold air.
But if I recall, one side is blowing cold and the other is warm. Will be of interest to know what was wrong.

I can direct airflow where needed when I select defrost/top/bottom vents, but the temperature , but driver side is ambient air at best. Wife took the Mustang earlier this week and commented that she never felt AC on driver side but held her hand over the passenger vents and the AC felt a lot less cold after 7mins or so of driving.

I'm just as skeptical as anyone else, but I am going to get a breakdown tomorrow morning from them as maybe there was something I missed or that the service manager didn't fully explain. When they called, my mind had already checked out for the day, and I was relieved when they said it wasn't the EVAP core.

Yeah sorry, I can see how that's confusing, but my mind was a giant fog when they called lol.

Well if the passenger side not cold after 7 min definitely not a damper issue.

I haven't spent much time as the passenger in the car. But even with our longer drive last weekend, if the other side was at least blowing cold for the entire duration of the drive, then the wife wouldn't have commented tp me that the AC didn't seem like it was working very well.

If the clutch was not engaging, will be no cold at all
Not the issue

So, dealership determined the clutch on my compressor was the issue, and it was constantly engaged. There were no leaks in the system (thankfully) or issues with actuators. They didn't have to replace the entire compressor, and only need to replace the clutch. I asked for a breakdown of the process and they mentioned having to capture all the refrigerant (which furthermore validated no leaks). They did mentioned when they were diagnosing the issue that the low pressure side had a little more pressure than normal, but no signs or indication of a leak was present.

Picked up the car today and the AC has never been colder, so fingers crossed this was it.

having the same issue as OP, hot air on driver side, cold on passenger side.

which part is for the driver side?
