Electric door locks on 1998 Ford Windstar

The door locks on all doors except the hatch work intermittently when I use the remote. Sometimes they all lock/unlock and sometimes it's just one door, mainly the passenger door. How can I make them work consistently again?

The door lock actuators in each of the offending doors will need to be diagnosed. It could be that one by one these actuators have failed on your 1998 Ford Windstar. The only way to know for sure is to have someone qualified in automotive electrical system diagnose your automatic door lock issues.
