Can anybody give me instructions on how to remove the interior door trim (front/passenger side) on my 00 ford expedition, 4x4?

Theres something squeaking inside the door mechanism when i drive thru rough roads. The sound comes up when the door locks are pressed down (locked) but the sound disappears when the door locks are up (unlocked).

I would like to see the inside, maybe something in the mechanism needs a little lubrication.
