I have a rattling noise coming from engine area when the car is in Reverse and Drive as well as AC is turned on. Heat shields are all fine, changed the belt tensioner, wedged the motor to see if motor mounts are bad, but still the noise is there. Is there any solution to this noise?

If t only does it when a/c is on it may be the compressor clutch or compressor going bad.

It makes noise after the car warms up. Makes noise either a/c is turned on or after I put the car in D and R. No noise in P and N. Even if the a/c is off, it rattles in D and R. Went to many mechanics nobody has solutions

Without actually hearing it I really can't give a good diagnosis
