Funny noise when a/c is on?

Hello,
More trouble with the 600. When I have the air con/heating on set at medium fan speed it works seemingly okay. It does have a slight squeel/squeak though, and when I turn it to high it seems to die out and make a vibration and a lower toned (deep) noise. Any ideas? I just replaced the heater blower motor, but that did not fix anything…

I currently have the same problem on my 2005 C230. Any ideas?

I wish. I replaced my heater blower motor (a $900 part ) but that did not fix anything. After my exhaust work gets done (600 cell race cats and resonator delete) I am going to drop my car off at the MB repair indie in town and have them fix it. I will definitely post up what it was when they figure it out.

Alright so I looked around and I am suspecting the A/C compressor itself is going bad.
