Dehumidified Defrost needed?

Do a little hot rodding and make a diverter inside.


2 holes, a piece of 18 gage steel, a piece of 1/4 inch rod, a few bends, a few one way washers and your in business.

That gives me an idea…. What if I found a 2” throttle body and adapted it like you’re talking about? Either find one that’s a 12V drive by wire and switch it, or run a separate cable operation for a classic throttle body?
