Default Ac problems

So I have a 2009 ram 1500 hemi. Just yesterday my ac went out, thought it was strange cause it has been working to perfection and boom nothing. No y’all tale signs at all of it going out. So of course I went on the witch hunt to find out what the problem could be. So first I checked the r134a level and it stated it was filled and not leaking. Then I proceeded to check for leaks at all areas of the ac systems and couldn’t find any. Checked the ac Compressor and saw the clutch was not engaging, however it was not seized as I could turn it manually with my hand. I then went on to check all my hvac fuses and they were fine. The last thing I have to check is the ground for the compressor and wiring harness.

Please if y’all can give me any advice I would love it! It’s july in Georgia so it’s hot!!! I will be taking it to a mechanic in a week if I can’t find anything.

I forgot to mention that I have already had the evaporator core replaced about a year ago.

What sometimes happen is the wire going to the magnet clutch rubs through. Also- check the pressure sensor- when the sensor notices either a high or a low pressure, it disables the AC. Also check the AC switch- sometimes it's just a little contact issue. When the compressor is not locked up, the clutch works and the system is filled, there is not much to it.

It's on attached to the pressure lines- you'll see it- it's the aluminum lines going from the front to the rear. There are those filler- flanges and then there is a sensor with some wires coming out- that's it.
To be honest- if you don't know, I doubt, you'll be able to test it- you might be better off bringing it to a shop.
