Hello everyone, I greatly need you guys assistance and suggestions.

Basically a couple months ago, my car used to make this grinding noise, the problem was intermittent. Now the problem came back in the winter and it hasn't faded away like before. I narrowed the problem to my AC clutch, I do not know if it is the whole clutch of just the bearing, I figured it was just easier to replace the whole clutch since it has the bearing included.

Also, a couple weeks ago when I would press the AC button, I would here it kick in. Just now I tried to test the AC to see if the clutch kicked in, the clutch would not engage.

What could be the problem of this? Could it be that the AC clutch is just in its entirely, going bad and causing it to not engage? Was it caused because I let the noise happen for a while now and it just eventually messed with the clutch?

Thank you guys, your advices are greatly appreciated!
