AC compressor, loud squeal for 20 sec then quit, no pressure change on gages, 2010 expedition

[Thomas Koenig]

I was in a parking lot with AC on and I heard a loud squeal for about 20 seconds and the AC quit. I added some 134A. Put gages on and pressure was 110 on both high and low. I spun the clutch by hand and it had some resistance. I then started the car and turned on the AC. The clutch turned but the pressure on the high side did not change.

My theory is when it squealed for 20 sec is that the clutch seized up and the serpentine belt made the squeal. Then something broke when the squeal stoped and the AC stoped working. It makes no sound now but the clutch turns when the AC is on. Maybe the clutch is slipping so the compressor is not working?

Any Thoughts?

Here's someone who had a similar problem. It was the clutch after all.

2008 navigator - No pressure changes when compressor is on

Just picked up this vehicle site unseen and took a gamble. Still worth it considering the price however AC is inop. Checked pressures with gauges and static is showing 85hi and low @ 80f ambient. The compressor struggles, and sometimes "squeals". Ok, it's more of a continuous honk sound, and the...

Thank You, it was the clutch.

Problem solved for $52 with 5 min fix.
It was the clutch. I found a YouTube video by FordTeckMakuloco "Ford F150 & Expedition A/C not cooling: Crazy Compressor Clutch Failures!" https://youtu.be/W62U7zFrQR4?si=acbKTDwXpv41j1vG

It had the exact same squeal and symptoms. Starting in 2004 for F150 and 2007 Expeditions Ford started using a clutch with a rubber part that dry rots. I live in south Florida where rubber dry rots real fast in the heat.

Yep, happened on my 07 F150. Easy clutch swap.
