Replacing door jamb switch?

[coppertahoe]

Hey the dome lights stay on in my truck even if my door is closed so i am asssuming that switch is wore out. In my obs it was a push button thing and really easy to replace but in this nbs i bought i dont see it anywhere

it is incorporated into the latch. Many have the opposite problem, that the lights don't come on. Have you tried spraying some WD 40 into the latch?
