I have a 2000 cavalier 2.2 engine and I'm a do-it-yourself'er and i want to find the best approach to fixing my broken compressor. I have AllData 9.9 so i don't really need any diagrams but I do need to know what i should be looking for in fixing my compressor. whatever the mechanism that is away from the compressor itself and sharing space with the pulley that should spin when the a/c is on isn't doing it anymore. i want to try to fix it to save money but i don't want to waste my time if i should really go for a working one instead.
