i was wondering if anyone could give me some advice on a problem i have. latley my car has developed a squeal that only gets worse when i accelerate. i took it to the mechanics and he said it was the air con compressor. but the sound doesnt seem to be coming from there in my opinion, it appears to be coming from one of the pulleys. the mechanic said he pulled the belt off and didnt notice anything wrong apart from the compressor. should i get a second opinion or should i trust him? also will a vy compressor fit on my vt?
