1989 camaro a/c clutch
 

hello every1 im new to the camaro world i dont actually drive 1 but im trying to help my cousin fix his. yesterday when he went to start it it squealed we discovered that the a/c pully was causing the loud squeal the a/c hasn't worked on his car since he got it last year what would cause the a/c clutch to fail is there anyway to bypass that pulley completely?
