heaters & defrosters in 40s & 50s trucks
I would like to get a 40s or 50s truck & from pictures I've seen, it doesn't look like some of them have defrosters. Can anyone enlighten me?
Thanks in advance.

Re: heaters & defrosters in 40s & 50s trucks
Most of these trucks have a heater just like a modern car but alot simpler. There are 2 vents that carry warm air from the heater to the windshield, when the heater is not directing the air to the windshield it directs the heat to the floor (or a combination of both). I have a schematic of the heating system somewhere, I'll have to find it and post it for you but it's pretty low tech!

my 57 has a DeLuxe heater, it's like a metal box under the dash. there's 2 pipes sticking out of the top, hoses go from there to the defrost vents at the bottom of the windshield.

Re: heaters & defrosters in 40s & 50s trucks
Some don't have either. If you look at the firewall of an AD (1947-55.1) Chevy truck the passenger side will have the fan motor sticking through. OR it will have a flat, round block off plate held on by 3 screws. I've had several trucks with no heat/defrost. It might have worked in the south but here in the midwest, it isn't such a good option to go without!!

Heaters were an option, lots of southern, southwest and CA trucks do not have them.
