AC Compressor?

AC Compressor?
hey guys--
so at some point i melted my ac tensioner pulley/belt setup. i bought a new belt and plastic pulley and installed it but it just screeches like crazy or if i tighten it the car won't turn over.. the ac compressor pulley does not turn at all by hand (though i'm not sure if it's supposed to?) so i'm thinking maybe there's something wrong there as well.
ideas? i'd rather try to figure it out myself than take it to someone. i thought a new belt and pulley would be sufficient but there's something else going on. also, i should have taken a pic of the spaghetti mess that my belt became cause we all know threads fail without pics.![Aroused](https://www.rx8club.com/images/smilies/aroused.gif)
thanks!!

More then likely the compressor is seized but here is how you can isolate the problem. With the engine off and no belt on the system; check the clutch for clearance between the pulley face and driven plate. If there is no clearance, the clutch is seized. If there is clearance, see if the pulley rotates freely; if not, you will need to replace the bearing. If the pulley rotates the next check is the compressor. Get out your 3/8 drive ratchet and socket that fits the nut holding the clutch plate on, try to rotate the clutch plate in a clockwise direction, it should rotate easy.

Have you ever figured out why the system locked up in the first place? Have you ever done this type of work before? If not, I recommend you read up on everything involved. The expansion valve is the device which lowers the pressure in the evaporator making the system cold.
Parts you will need are compressor, clutch assembly, assorted o-rings and expansion valve. I don't recommend used parts, especially the expansion valve. You will also need a flushing solution and a way to flush the system; freon, oil, a gauge set and vacumn pump.. I would also recommend you remove the condensor and clean it if your inspection shows it to be serviceable.
