Have you ever seen any Dart, Valiant, Demon or Duster with a rear window defroster?

My Duster has a two speed rear window defogger with blower:

1971 Plymouth Duster 340 (export car)

The switch is aside the map-light - switch under the left side of the dash:

Cool. Thank you! I can’t see any switches like that in my pictures. I didn’t really take one from that angle
