Chevy Traverse - Easy Fix for Radio Speakers not working due to water leaking onto door wire harness

It appears to be a common problem with Chevy Traverse and GMC Arcadia that water enters the wire harness connections on the doors when it rains. This is one easy solution to help keep water out.
Sorry about the video orientation, I can not get it to rotate to the correct position. UPDATE: Note the comments for more detail, but the speakers had to be replaced. Although there is a water issue, water was not the cause of this problem.
