noise from aircon

[nemad]

Hi, seem to have a slight knockin sound coming from my motor in my SS, only comes on when I crank the A/C, can anyone help pls

if it only makes a racket when ur air is on then it could be a rubber insulator that sits on the front of the compressor pulley assembly has let go. common problem. mine did it brand new and i had the compressor replaced under warranty. i'm not sure but i think theres a techline (recall) for it

also if u drive it hard with a/c on u will keep stuffing the compressor..
