2000 GT power lock problem

[Cjburn]

I was programming a spare fob for my Mustang when I realized that the door lock sticks in the up position and does not come down unless you push it down. IF you manually lock and unlock it, it will lock and unlock itself (either fob or power switch) once and only once, then stay unlocked (up). It will not lock, the passenger door works fine. It's almost like it gets stuck unlocked, until you push it down yourself. Weird...

sounds like the actuator is starting to fail.....
