What did the VW beetles use back in the day? They were air cooled, no heated seat.
Didn't they use a heat exchanger of some sort that was heated up by the exhaust manifold or something? It's been so long I don't remember.
Yes they blew air over the exhaust manifold. Called them heater boxes.
When was that? I had one that was a '69 model (can't be sure), and it got cold as all get out if stuck in traffic.
