I installed a small computer fan into the bottom of the driver's seat.. It's a 12 vlt, 120mm I think, borrowed from my computer. It will just slide right into the notches under the seat if you use 4 screw left seeral turns from being tight. The seat didn't even need to be removed!.. which I found out after unbulting the passenger seat. Anyway, the fan isn't one of the strongest, but it's pretty quiet; I'll try a few different ones and see which is the best. Does anyone know if was intended to send air into the seat or extract?.. mine is sending. Also, I would think there's one more for the back but am not brave enough to completely break the seat down. Let me know
