Heater blower fan quit. There is no power to the dash switch, but the fuse is good. What else do I check?

I just looked at the old wiring diagrams and it appears there is a mistake in the one for the El Camino because it omits the power supply but I looked at a Corvette for the same year and it shows power coming from the fuse box on the brown wire to the switch. They had a history of overheating the connectors and losing contact.
