Hello. The way to correct this problem is to simply replace the A/C compressor unit in its entirety, along with the serpentine belt. The other pulleys need to be checked as well, to make sure they are not causing problems. I suggest you have a certified technician, like one from YourMechanic, come out to run an inspection on your AC system.
