I'm currently fabricating a ventilation system which pulls the air from the 2nd row to the rear facing seats. My kids get hot/cold back there and I needed a solution. Here are my goals with this system: 1. Make it look as much like an OEM unit as possible 2. Quiet and yet providing enough air to be effective 3. The system only blows air from the 2nd row. It does not heat or cool. 4. Easily installed and removed 5. Low current draw 6. Compatible with all markets (US, EU, AP) I'm making them for my kids first and they'll get the benefit of the prototyping. However, if the demand is high enough, I'll gladly mass produce these. The addition of the sun shade for the rear hatch will help a lot, and I'm getting it as soon as it comes out, but here in Texas the summer heat is going to be a big deal. When some of the molding is done, I'll post pictures here. Once I get an idea of manufacturing costs, I can give an estimate on pricing. Let me know if you want on the list. Thanks!
