Before you replace the switch, check the fuse box. Its parts are riveted together and often become corroded and things don't work even with good fuses. I took my fuse box apart a number of years ago and soldered the pieces together. The truck runs better since then than when 5 years old.
Labman nailed it. Super corroded ground in the fuse block. Can't wait to get my swap started, swapping to a blade fuse box!
