You probably have bad bearings in the A/C clutch pulley. Remove the drive belt and spin the pulley for noise and shake it around for play. Any noise or play and you need a new clutch. Also see if the front hub on the compressor turns easy. If not, then the noise could be the compressor locking up. Reman compressor might be the least expensive route.

2000 Chevy Cavalier making a noise when air is shut off


This problem sounds like the aircompressor pully, the bearing is shot.
With the engine running and the air conditioner off there is a grinding noise, look at the compressor pully, does it wobble? Then turn on the air conditioner and the noise stops, look at the compressor pully again, the wobble stops? If so that's the problem.

your front brake pads may be metal to metal (worn out) or there is a small rock stuck in the rotor area, onluy way to know is pull the front wheels off and inspect the brake pads and the rotors

How many lbs. of freon for 2000 chevy silverado 2500 5.3ltr.


if its a new body style (with the round front - i am assuming because it has a 5.3) then it takes 2.0lbs (.91kg). Make sure you check your fan clutch to see if it spins freely or has some drag to it. the fan clutches usually fail causing the compressors to come apart, the failed ones spin freely.

it is almost impossible to solve without hearing it in person, but some things to check are the front brakes, front wheel bearings, tires, and loose suspension parts.
