96 850 GLT Lock buzzzes

[Bert]

When I lock the doors the right rear door lock buzzes for a couple of
seconds and then locks. It's been doing this for a few months. Now it buzzes
but wil not lock so I have to press the button down. (occasionally it works
perfectly)
Comments anyone?
Thanks, Bert

You might pull the door panel and see what the mechanism looks like, the
buzzing might be a mechanical thing, as an alternative you could let your
mechanic look at it.....
