Question Anyone notice this sound ?

I've been hearing an annoying buzzing/humming electric sounding noise coming from under the hood only when the AC is on, the noise is like what a neon sign sounds like and its best heard from outside the car. I had MB replace the AC compressor but the noise is back and I need to know if any of you have heard this from your car and or had it corrected.

Thanks

Are you sure that's not the engine cooling fan going into high speed?

I forgot to mention that the noise only occurs after a half hour or more of driving.

I have heard that exact sound. The service department has told me that the sound is coming from the AC compressor and that its a normal sound on european cars???
