Best Answer

it is probably the bearings going out in the ac compressor pulley or belt slippage. the reason it is different when it is on is because the belt is not under "load" or has resistance.

What exactly is an ac compressor?

An AC compressor is part of an air conditioner which may be used in a car's AC system. The compressor is used to change the pressure between the AC's compartments in order to help condense the refrigerant gas back into a liquid.


Where is the ac for a 2001 Saturn SC1?

The AC is a "system", not a single component, and as such, there are parts of the AC system in several areas of the vehicle. The AC compressor is on the engine and receives it's power from the serpentine belt. The AC clutch is on the compressor, enabling the compressor to be disengaged from the serpentine belt when the compressor is not needed. The AC evaporator is a coil that 's inside the heater box, under the dashboard. The AC condenser is in front of the engine radiator. The AC receiver/dryer is under the hood, attached to the firewall. And the AC refrigerant hoses connect everything together.
