Vibration and Moan when AC is on
 
I have recently been experiencing a very loud vibration/moan when the AC is on. The vibration feels like I'm driving over rumble strips. It occurs when accelerating, coasting, and idling. There is no issue when the AC is off. I took it to the dealer and they said they've never seen anything like it. They emailed Chrysler and are awaiting a response. I will provide an update in case anyone else has the same issue.

Thanks for the heads up. Haven,t had anything like that happen. Will be interesting to know what is causing your noise.

I have something similar. Mine is high pitched squeal at low RPM low speed. Just brought my GC to shop and the techs can't figure it out. It only happens at certain RPM / speed combos and only when the AC is on. When it is squealing and I turn the AC off it goes away until I turn the AC back on.

I have short periods (2-3 seconds) vibrations coming from beneath when the car stands, havent notice if the AC is on or off. The feeling is like the ground vibrates below me.

There is a TSB for that issue. I had the same problem, but got it fixed last year.
