door lock actuators?
I was the team leader on a door latch and lock line for Delphi for over 5 years (we made some latches for Ford so don't shoot me) I also repaired them. I would understand if one actuator went bad but both at the same time sounds like something is up elsewhere. One may fail sure it happens but both.. No way.
my passenger side went out and then not long after my drivers side actuator went out, so it is possible. there not expensive so i would just replace both of them, since it sounds like thats your problem
