The AC compressor will come on with the defroster, but not just the heat. (the AC evap coil is used by the defroster to dehumidify the air blowing on the windshield). If the compressor is cycling on and off it's usually due to being low on refrigerant. If it's grinding, then you likely have a problem with a bearing.
