OK, this is a weird one to me.

'93 Acura Legend. When I lock the doors using the switch on the door
(no remote lock/unlock), the majority of times it will lock itself
just fine. About 25% of the time, it will lock, then lock again
anywhere from 1-6 times. I cannot find any specific thing attached to
replicating the problem. Could this be a simple fuse or does anyone
have any idea? I don't want to drop some money on having it looked at
when I never know if it is going to do it or not.

Thanks in advance.
