Hi there,
My daughter experienced the same weak locking a few months back. No problems with the door switches this time, and fuse 8 was clean. But it took two, or maybe three pulls on the button (or key) to get the lock all the way up.
Looking closely, the rear left door was the most sluggish. Because I'd seen water leak into these sealed door lock actuators before, I opened that one up first. Sure enough, once I disconnected the rear left motor (blue plug at the base of the B pillar) the other locks responded crisply once again.
Inside the lock actuator was a rusty motor. The "recharge" you feel is, I believe, a function of the PTC thermistor (overload protector) in each door lock. As the current increases from a stalled motor, it warms up, limiting the current increase, and allowing a bit more voltage to appear at the remaining locks. Of course, if one isn't more sluggish than the rest, you may have more than one to fix. The blue plugs at O and R in the wiring diagram make good places to isolate the culprit.
