Working on a 1952 Chevy truck (3100) and it does have an original heater box mounted to the inside of the firewall. Upon closer look, it is not wired into the truck and there are not any defroster ducts in place.
But my question is, how did those heaters operate? I see a switch is offered in aftermarket catalogs, but where did the switch go in the cab? Anyone have any pictures?
Thanks!
