The flush chemicals are pretty expensive but at least they have them in a version that doesn't require a whole flush kit and an air compressor.

If the compressor will still "turn on" is that a good sign it might not have completely imploded?

That would be great, once the snow stops and I can get out there I will kinda see how much play I have in the pulley now. I have AAA too if I try to get there and it fails :lol:

In the Honda world, this is known as "Black Death"...lol.

One of the main reasons I quit looking for an 02-06 CR-V a few years back, way too many with either broken A/C or a contaminated system asking for another failure.

It gives a glimmer, actually more than a glimmer, of hope.

This may all be the clutch bearing which you can deal with without vacuuming and recharging the system at all. There are a couple of threads in the repair database that give some part numbers for the bearing itself and go over procedures for pressing out the old one and pressing in the replacement.

PS: For temp fix, don't turn on the AC, or simply remove the AC relay in the fusebox near driver's side firewall area. Photos in forum.
I couldn't find a good picture of the AC relay, and the only thing I saw in the firewall fusebox was a fuse that disabled the whole HVAC...I pulled the glovebox and found this relay...AC?

That is indeed the AC relay. Removing it will not help a clutch bearing problem though.

Just for future reference, the device next to it with the larger Black and Blue wires is the power stage which is a fancy solid state blower resistor. Not that yours is bad but if the fan gets stuck on high speed or quits altogether that is where you look.
