this switch had previously been replaced before i got involved, and luckily, my buddy kept the old switch. it is plastic, so i popped it apart and discovered it was kind of melty
This is another clue to a connection issue at the switch. Over heated and melted is a sign of a poor connection. Like I said double check the spade connections. If possible remove them and squeeze them tighter and see what happens. Also watch the white grease best to use dielectric.
