Using a set of a/c gauges both the low and high side readings will be of equal value, meaning that the compressor has equalized or its very noisy.......
From what I know, the A/C compressor is going bad. The accessory belt turns the compressor, and in your car, that part of the compressor is going bad, so the belt meets too much resistance; hence the squeaking. Had this happen to my car, too.
You have a certified shop do a system performance test, unless you know how to perform such a test yourself with a manifold gauge set.
The condenser usually leaks and that makes it go bad. Also it can become clogged if the compressor goes bad and pumps metallic particles through the system.
the ac belt or the compressor bearings are going bad
They can get noisy and leak oil. You want to replace a noisy ac compressor before it fills the system with metal trash.
Typical causes of a compressor not running are: low coolant, blown fuse in compressor circuit, bad compressor, bad temperature sensor.
Check for a blown fuse in fuse block and also at the top of the compressor Bad switch Bad compressor clutch
Bad bearing in compressor? Bad bearing in compressor?
If the clutch disengages properly then the compressor should not be running. Most likely the clutch itself is bad instead of the compressor.
How can I know with no more information than this? Seek out professional help.
