hey all. got a ba xr6 turbo ute and a weird topic but its quite annoying also as ive put up with it for a while now. everytime I put my aircon on I get this weird almost like speaker squeek ticking but the moment I turn it off it all goes away. I have no idea what it is but it has nothing to do with my radio as I turn that off and still ticks away. anyone else had this problem and fixed it? if so how... thanks guys
