The compressor should have an electric clutch so that it is disconnected at start up. The A/C compressor is used when the HVAC is at full window defrost. My Pontiac HVAC has two selections for windshield defrosting. Don't use the highest level until the compressor is healthy.

It must be locked on you can hear it when you start the motor.

If the clutch is worn it will also make noise when disengaged.
