So I don't think I've ever had a car before with defrost vents built into the doors before, but after having my '89 Supra for almost 5 months now, I'm not sure what to expect for the ones on that car and how to get them working. I have refurbished the climate control buttons, and every other option seems to be working nicely now, but I can't figure out what is required to get air to blow through those vents in the doors. Is something likely broken or is it supposed to be some kind of passive system? I didn't see anything in the owner's manual about this.
