I discovered that having the vent resulted in a much cooler car when I parked in the sun (I monitor the inside temperature with a digital thermometer). The vent lets air in / out, but keeps rain out. However, I found that if the windshield was facing into the sun, the air would still be much hotter than the outside (it could reach 135 degrees).

Because the vent is about 2 feet lower than the roof of the car and located in the front of the cabin, heat inevitably gets trapped. So, the next solution was to place solar cells on the dashboard to power small circulation and exhaust fans. That still doesn't bring the inside temperature to the outside temperature, but it does keep it cooler.

Since it is now fall, I already run with one vent closed due to cooler weather, I haven't yet tried putting a reflective sun screen on the windows.But I am fairly certain that would also reduce peak cabin temperatures.

Great idea! Do you have pictures of the design/install? Thanks.
