1994 Ford Escort Improper Power Door Lock Operation

Depressing the driver's door lock locks all other doors, as it should. Lifting the driver's door lock unlocks none of the other doors, as it should.

Replacing the driver's door power cable and relay has had no effect on operation.

I have found that with rapid activation of the driver's lock
one may be able to obtain lifting of the other locks in perhaps 10-20 up and down cycles. What do you think?

Thanks for your help.
