Default a/c noise when in auto

09 sierra - anyone else notice noise when braking if the temp control is in auto? Only when slowing to a stop, and only when in auto temp cycle. From under the dash, sounds like a heavy wire tie hitting the radiator fan. That faint of a sound but wonder if anyone else has noticed it.
