All automotive air conditioner compressors work by going on and off. That is how they control the temperature. If they are mostly off, they make it warmer. If they are mostly on, they make it colder. The fact that it is on an Impala has nothing to do with it. The fact that it is an automobile air conditioner compressor has everything to do with it. Something would be wrong if it was not going on and off.
Bad compressor
From what I know, the A/C compressor is going bad. The accessory belt turns the compressor, and in your car, that part of the compressor is going bad, so the belt meets too much resistance; hence the squeaking. Had this happen to my car, too.
the a/c compressor cluth is bad. should make a grinding noise when not on and goes away when it is on.

Yes, if the compressor's bearings are bad, usually accompanied by a roaring or squealing noise coming from the compressor's pulley.

Checking the pressure of a fridge compressor is easy. Remove the compressor and give it a shake. After taking the compressor off it should make a sound while shaking that means itÕs still good if the compressor makes no sound that means it has went bad.

If the dome light will not shut off on a 2002 impala, check for a water leak in the roof that might interfere with the operation of the light. Also check for a bad connection with the ground wire or a short in the wires.
There could be a few reasons why a 2000 Chevy Impala shuts off while driving. There could be a problem with the fuel pump, a bad spark plug, or even a loose battery cable.
