I see Dorman/Help has door jamb switches available for about $13, So call your local parts stores and see if they carry Dorman parts and the labor time to remove and replace this switch is about 3/4 of an hour

How do we find out which door it is?

Usually its the drivers door because it's opened twice as often as the others
