2001 Pontiac Sunfire Repair Question
What is wrong with my car?
So this noise is only when you turn on the air? If so if should be safe to drive as long as you dont mind not being able to use the defrost feature with uses the ac also.. But your problem sounds like major compressor failure. dealing with ac you can have the ac system evacuated and replace the compressor yourself and have a shop service the system then.
