Grinding sound from AC

Howdy everyone,

I just got a new noise in my Jeep.

When I first turn the A/C on, it sounds like grinding, but it is not a constant grinding sound, kind of like grind for a second, stop, grind, stop, and after about two minutes of operation, the noise stops entirely.

When the truck is warmed up, the noise does not come back during start up, only when the motor has been sitting. Any ideas?

I have seen issues in the past where rust will build up on the clutch of the a/c compressor, so when activated, a grinding noise will occurr. More than likely though, the a/c compressor is on the way out.
