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?

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