whenever I turn on the AC I get a shrill whistling sound when I try to pickup in the lower rpm. The sound turns into a constant whistle/humming at cruising speeds. The sound is not like a screeching sound, which suggests a loose belt but like that made by a motor. Has anyone experienced this? Thanks

 

does it only happen with the A/C turned on, or with it off as well?

 

maybe your intake??

 

It just happen when the A/C turned on. I doubt if it is from the intake.

 

brother....i get that noise too when the A/C is on....it actually sounds pretty cool lol....i dunno what it is either...
