After removing the door vent channels slash armrests, all of the fresh air was coming out of the lower vents. Instead of capping them off, I designed and printed some covers that direct a little air upwards, but create enough backpressure to allow the dashboard vents to work.
Funny how there’s fresh springs and hardware in there, but the OG cylinder. Fuck you, PO. I only did the driver’s side, though, because I don’t have enough brake fluid on hand to refill whatever I spill and bleed doing the other wheel.
