When I press the unlock button on my remote or in my truck, the passenger side power lock moves a little bit but doesn't come the whole way up to the unlocked position. I thought at first it was just a lube issue so I took off the door panel and lubed everything and it worked fine for a couple of weeks. Now it is doing it again, I suspect that Ford built in a compacitor to protect the motor because if you press the button repeatdly it just gets weaker and weaker with each press. Any suggestions would be helpful.

 

It's probably time for a new actuator.
