Air Conditioner Compressor Issues

[JMR]

My fan is screaming in the driveway when the ac is on and truck not moving, very loud actually

I think (hope) what you're hearing is normal. The cooling fans are loud and it sounds like an ICE truck running when they're on.

I hope the hack gets resolved soon and I won't have to wait a long time for parts/repair

It was resolved a day or so ago.

FYI your compressor noise sounds totally normal for the electric compressors in Lightnings/Mach-Es/etc.

The fact that it ramps up and then shuts down is obviously bad, but the noise is normal. Obviously, the AC system is encountering an error and shutting down the compressor.

I'm surprised a dummy light didn't go on. Did you ever get an OBD error code?

No, the truck is not throwing error codes. I disagree that the noise is normal. This is the third summer I've owned the truck and the noise didn't start until the end of last summer. I took it in to have it looked at when the noise first started but the dealership claimed they couldn't replicate it (it wasn't consistent at first) and, because is was working, there was nothing more they could do.

From your video, it sounds like every other Lightning/Mach-es I've heard.

But some people have said it gets louder if the refrigerant is low. Did they try adding any? If refrigerant is low, some AC systems will automatically stop the compressor to save it from damage.

It does work continuously as long as the truck is moving which makes me think it's probably not a low refrigerant issue, but maybe it is.

Nothing's been done yet. I goes in on Monday. I'll update once I find out what the problem is.

My AC compressor is definitely loud and ramps, but I don't think it has ever sounded like that. I hope the dealer is able to pinpoint the issue.

I've owned 2 Lightnings. The first one didn't sound like what you posted. The second one does. I'm taking mine in to have it looked at as well.

You miss understood. I don't think anyone will ever say their A/C is not loud, just something we're going to have to live with. It's the particular sound that it's making that is a concern in this thread. Mine sounds like an ICE engine idling. Nothing unusual about it (ignoring the volume of the sound).
