The power locks on my vehicles have jammed totally. You can deform it a little bit by pressing really hard, otherwise, the bits of the lock mechanism won't move at all. However, they are attached to a motor.
The lock elements themselves don't look to be attached in such a way that is very removable, so it makes me wonder if the motor might be the part that is actually suck cold. The only way to test it appears to be to remove it totally, however. I bought the car mostly like this; also, I hit the mechanism with P oil pretty thoroughly and it has no effect.
(I have an endoscope if anyone thinks posting a video of it would help.)
