Rear noise outo my a/c compressor now my a/c don't work what can be the problem?? help please

 

it may have siezed up. check belt tension, wiring/fuses, and if they are ok you'll need a new compressor.

 

x2.. typically when an a/c compressor is on its way to siezing up.. they will make a noise everytime it kicks on.. try turning it by hand.. if you feel some restriction or its not turning smoothly.. its on its way

 

i have a full ac system for a dc integra if you need

 

that will only test the pully, not the piston inside the comp. you'll need the clutch to be engaged to feel the restriction.
