Thanks for the welcome.
The heater works. There's a unit right below the glove compartment dash that let's you turn off or on. The knob is missing, but it turns. I'm not sure if it's stock, as it has a "Nichiro" label on it. Maybe someone can verify this.
Even has a cool "wiper delay control", that delays the slow wiper even more...lol.
