Engine noise while accelerating with A/C on!

[rossgoldie]

Ok so I just got my ac fixed at the mechanics, new fan, blower, and had the heater core cleaned out. It works great except for one thing. When I accelerate with the ac on, either the blower or fan (idk which) gets much louder with the acceleration. The sound stops when I turn the ac off. It kinda sounds like a shitty and overly loud supercharger. I am going to the mechanic tomorrow but does anyone have info on this for me? Is this normal or no?

Probably the bearings for the belt for the compressor are going out.

See whether the sound stops or weakens if you select the fan speed to 1. If it is compressor it will come regardless of the fan speed.
