Auto door lock problems

My early '99 F350 crew cab is having trouble with the door locks.. All 4 locks either work or try to work without success as if they're not getting enough voltage to operate occasionally, it's been getting more frequent. If it was one or two doors I'd just replace the actuators, but it's ALL of them. What control module provides the door lock function? I'm thinking it's gone bad.

It is most likely the actuators. These trucks are bad for that. I have replaced MANY for the same concern.

Read through this. From what you say it sounds like your problem. I did mine some time ago and they are still working great.
