Hi all,
I have the exact same noise as stated in this thread here:

http://www.fordraptorforum.com/f93/air-conditioner-noise-16398/

Metal grinding sound a few seconds after startup. It has changed to a bit of a whine that goes away after about a minute of running.

I haven't seen anything new on the 2012 thread so either people just accept this or it is such a simple issue that everyone fixes it without posting. Is it the AC clutch (grind) and serpentine belt (whine) or maybe a pulley bearing? Bad AC design cant be it because every Raptor doesn't make this noise (Does it?)

Anyway. Hope someone has some experience with this.
