A/C idle-up not working on 22RE

My toyota pickup used to idle faster when turning on the air
conditioner, now it doesn't. I know it's controlled by the big hex
screw, but turning it while the a/c is on doesn't make any difference.
Is it something I can take apart and clean if need be, or do I have to
change it?

What year truck?

Is the AC compressor clutch actually engaging? What is the idle RPM with
and without the AC engaged?

Yes, the compressor engages. I'm not sure about the rpm, as I don't
have a tach, but when the AC engages, the RPM drops a bit.

If a/c magnet clutch is ok, then check a/c idle-up vsv.
