I need to know if the compressor locked up or came apart or if it just stopped pumping?

I was told it came apart.Of course that is what the two shops told me.They may have told me that so they can charge more.

Your welcome thats what were here for.Another thing get a ac get set they have some pretty cheap ones i got mine at harbor frieght with a 20 percent off cupon its not real high quality but for once in a while use it works ok.Just remember if you use the gauges to charge the ac system make sure the high side valve on the gauges is off and the valve on the high side line is off.While the charging cans are hooked up.Before charging Also see if you can rent a electric vacuum pump from auto zone etc and hook it up with gauges hooked up with all the hoses and valves open and pull atleast a 45 min vacuum before charging that will help pull moisture from the ac system.Also after pulling the vacuum turn the pump off and then close all valves then watch the gauges for the pressures going up and vacuum escaping for mins wait time.I would also put leak dye in the system in case you have leak later on.Let me know how it goes or if you run into any problems.Also make sure you balance the compressor oil when changing the ac compressor.
