Is the center of the AC compressor pulley spinning with the belt? If not, your compressor is toast, time to replace it. There is not clutch on this compressor.

Ok, so if the center of the pulley is spinning next thing to check is the light on the EC button turn off when you press the button If it does that means all the inputs to the ccu are working properly and it's telling the control valve to activate the AC. If it's not working at that point the only failure point left is the compressor control valve. It's something like this.

It's a vw video but the Mercedes ac functions the same way.
