The door jamb switches are self adjusting, to adjust to the different gaps between the door and the door jamb on different vehicles. Sometimes this self adjusting feature "slips", and the switch get out of adjustment. If that happens, it often helps to take a pair of pliers and pull the switch out to the fully extended position. then close the door and let the switch readjust.

In the picture below, the tubular part, to the right of the of the hexagon part, is the self adjuster.
