ac problems

I have a 1999 E-320 with an intermitten ac problem. I had it to the only shop within 300miles that will work on Mercedes and they pulled the codes and got B1416. tested the Coolant Circulation pump and told me it was bad. I am thinking this is the electric auxillery water pump , correct me if I am wrong. Does this sound like it could have something to do with my AC problem.

I do not believe that the elect aux recirc pump has anything to do with the A/C. As for repair of the A/C itself I would go to an MB dealer as if it is caused by any of the electronics or regulators they are the ones that can fix it. If it is caused by any very basic stuff like low freon, leak, etc the A/C shop would have done just fine.
