No AC on 1999 Mercedes-Benz E320

I have a 1999 E320. My AC stopped work the other day. The clutch isn't engaging and the controller have defaulted to the EC Mode. I checked the fuse underhood and is OK. I checked freon and appears to be normal (although not sure since compressor is not turning).
Anyone have any advise as to the problem ?
