Electric door lock going crazy

[Qb3rt]

I have a ford explorer 1996 4dr EB
I can hear the door lock relay going really mad it's make a continous weird sound and the doors are unlocking every 50ms.... And when this is appening i don't touch anything

I changed the relay and it's still doing the same thing... For now i removed the relay...

Any idea about that problem?

I had similar thing happen to me, it ended up being a bad actuator in the p/s rear door. The locks were going crazy. I disconnected it and everything worked fine after that.
I still haven't changed the bad actuator, so we have to remember to manually lock that one door, ha!
