Noise coming from belts

[Fulltiltorgasm]

I believe the noise is coming from one of the pulleys/tensioners running off the belt, the noise is sqeaky kinda noise, worse when aircon is on, would it be the pulley off the air compressor causing this noise and its only minor at the moment, can it cause any serious damage as it gets worse? when you stop using the air con noise virtually goes away after a short time

Bearing in the clutch is gone or ac belt is loose

New belt + pulley usually fixes any squealing belts.

if its worse when the ac is on, its prob the ac belt just change it and take it from there!

THIS ^ start with the basics then if noise still prevails maybe tensioner first thing I would do is tighten the currently belt
