Took mine apart in my '49 1/2T. Got the switch out, pried open the fold down tabs and cleaned everything up well. Switch operates through a small steel ball and if that is gunky it won't always make contact. Put mine back together and its works. Sometimes you need to push the switch down into the socket a little to move that detent ball.
