My SO has complained about cold air on her feet in the passenger side of our Model S. Looking under there, there are 4 vents that leak cold air when the A/C is on, even if she has her side temperature turned up so high the heat is on over there. I finally got around to putting some memory foam in the vents for summer. What would be great would be a sliding door sort of thing that could close off these vents. I can see how to do it in my mind, but I don't have the tools to make it. When I was under there I found what appears to be the holes for something on the right side. You can see it on the far right in the first shot and a closeup in the last shot. It looks like Tesla had planned something to install there, but ended up never following through. I could see installing some kind of small storage bin up there (another aftermarket idea) with a slide out drawer. It's far enough over having something installed there probably wouldn't interfere with the passenger's feet. My parents had an Olds 98 back in the 80s that had a small trash can in that spot. Just curious if anyone knows what those holes on the right are for?
