It sounds like what happened to mine. Got louder and louder and then froze one day (while driving and broke the serpentine belt). If you think it's the AC pulley? Change the compressor soon and it will save $$$ on a tow. I got a nice used one for $80. Paid $75 for the tow home.

that's what mine did right before the compressor clutch burned up.... :/
