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.
Without the year, make or model of your vehicle it could be a bad compressor and or a bad compressor clutch.............
Yes, if the compressor's bearings are bad, usually accompanied by a roaring or squealing noise coming from the compressor's pulley.
If the clutch on the AC compressor has seized, the engine can in some situations stop running. The compressor could be bad but it is also possible that the clutch only is bad.
Either your Air Ride switch is turned off or you have a bad compressor. My compressor died on me because of a bad selanoid... have a mechanic look into it. be warned, it can get expensive.
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.
thermostat could be bad, or location of it, air flow over it.
compressor contactor is bad. probably stuck in the closed position.
I would like the answer to this question also. AnswerWhen you say "after turning off 1994...", I'm assuming you mean turning off the A/C. The clutch on the compressor might be stuck, or the relay that controls it may be sticking. Try pulling the fuse or unplugging the compressor connector and seeing what it does. If it still runs, you've got a bad clutch on the compressor. IF YOU PULL THE CONNECTOR AT THE COMPRESSOR, MAKE SURE THE ENGINE IS OFF BEFORE YOU DO. Don't blame me if you get hung up in the belt.
