Wooooo~ Sound

Post by potateo » Mon Oct 16, 2017 1:31 pm

Hi!
Recently i have noticed a Woooooo~ sound coming from my car.
It sounds like the one from the Alternator but softer and only comes on when:
1) The Aircon is swithed ON and,
2) Also slightly louder when you press on the Accelerator

Any idea what is the exact issue?
Pulley or Bearing?
or Compressor!!?!??!?!

Could be aircon compressor pulley giving way liao.

Idle your car with neutral gear........then pull the throttle cable from bonnet to hear where the sound comes from exactly.

Try with aircon and without aircon.

I done my compressor pulley change in msia for rm180 and works great thereafter.........but it's a trial and error as they dun have exact correct measurement and gotta try a few pcs and might not have the size.
