again, so I'm not sure what happened.  Last night I looked under at the
compressor while the engine was running and noticed that the clutch wasn't
running "true" but with a slight wobble.  After letting the motor cool off,
I reached down and noticed that I could push on the face of the clutch and
get it to move in relation to the pulley.  Is this normal?

yesterday after work and the clutch kicked in with no noises and I'm pretty
sure it was working because I could hear the rpm's drop when the I turned
the temp on the EATC down. No cold air though, because I'm pretty sure it
needs a recharge. However, on the way to work this morning, I heard a bad
belt squeal which lasted for a few seconds, which at first I thought was due
to the rainy conditions. However, when the squeal came back, I started
noticing rubber smoke coming from under the hood so I shut the climate
control off and the squealing stopped. So now that I have what seems like a
frozen A/C compressor, anyone have an extra lying around?
