Ok, I went back out to the garage to tackle the switch. I didn't want to be monkeying around inside the switch with the power hooked up. I disconnected the battery before I started.
I took the switch apart and looked at the internals. Everything looked ship shape. I put it back together and tightened everything up. Still no improvement. The problem is that all the wires and connections are in the bottom of the switch under the internals. There is no way to test the individual connections without taking the whole thing apart. I'm trying to figure out how to test the internal connections inside the switch. This is quickly getting way above my skill level.
In order to test it further I'll have to cut it back out of the truck and test it on the kitchen table with my multi-meter. For all that it might be easier to just buy a new switch.
