Power Door Lock (Driver side) issue
 

My 1997 4 Cycl VTECH driver side power door lock has problem for a few weeks. When I lock the car, it has a "vibtation" sound for almost a second. But the lock still work, no problem at all, just the wierd sound. About 2 weeks ago, the close door (driver side too) sensor got bad. It keeps telling you door not closed.

Do you folks know which part(s) have problem and how to fix it.

Thanks.
