So, my Jimmy started to make a loud High pitch noise. This noise is really loud, it is hard to pinpoint location, but it seemed to becomming from the passenger side of the engine. I thought it was a bearing going bad in either the AC compressor pulley or the Idle pully, but after replacing both it did not go away. It makes the noise after it has warmed up for about 10 minutes. It seems to fluctuate alittle when you press the accelerator, but it does it at Idle or at 70 MPH. Any Ideas? I've checked previous posts (wish I did that before I spent 50 bucks) if I do the "no belt" thing and it continues then what? Intake, throtle Body?
