My 76 has a rocker style switch near the drivers knee. It is on the lower center counsel near the toward the gas pedal. What does this switch control?

Rear defroster would be my guess.

It operates a rear window defroster fan, my 75's fan is right behind the drivers seat

It is the control switch for the C49 option, the rear window defogger. It was the first year for those tiny heating wires in the rear window glass. Before 1976, there was a optional blower built into the rear deck. The blower type was called a "defroster" system.

Thanks guys! That would explain why I don't "see" it do anything when I turn it on.

Roger,

It does, in fact, go down when I flip the switch so it must be working. I doubt I will ever use it but it is good to know what the switch is for. Thanks again.
