So whats the go?? Im new to the datto 1200 scene and I want to know if this can operate just as a normal fan and not as a heater(ie that it blows not so hot air)?? Hope this doesnt sound like a dumb question because Ive got bits missing everywhere in this car.

How do you turn it on??

*Note: There is one in my car already, this is a spare I got with the car.
