A/C Compressor

I have a 2005 Jeep Grand Cherokee with the 4.7. The A/C has worked great since the day we got it two years ago, until last week. My wife was driving home from work and the compressor locked up while the A/C was on and smoked the belt. The compressor is fairly new. I turned it by hand and it turns fine. I decided to take a little freon out for the heck of it and it pumped great after that but it isnt cooling now even though it runs. I added a little freon back to it and the pulley stopped and started squealing again. Could something be plugged? Why would it run when i take freon out and lock up when I put some in? Any ideas? Thanks!:confused:

Ideas anyone?!?!

Wow, that's odd that it works without freon and locks up with. There's obviously something very wrong with the compressor and a new one is probably in your future. It IS 8 years old, and although you didn't say how many miles are on the Jeep, I'm guessing over 100k?

It has right at 100,000 miles and the compressor is brand new.

Forget it. Figured it out.
