Door Lock doesn't work
 

I have a 2001 F-150 4x4 Super Crew with a 4.6 Triton.
The problem is with the door locks on the passenger side (Mostly the front)
When I hit either the remote OR inside door unlock switch, the doors do not always unlock. They lock fine.
My 1st thought is the door lock actuator. But... here is the weird part. :confused: When I try to unlock it with the key, the button on the inside still does not go all of the way up (I actually have to hit the remote twice to get it up the rest of the way). If I pull the outside handle up, the button goes back down and it is locked. If I pull the inside handle it goes all the way up without a problem.
The front door is the one that always gives me the problem but the rear does it every now and then.
I have not been inside of the door so I am not sure how everything is tied together.
ANY help is greatly appreciated.:thumbsup:
