I tried to remove the leather\plastic from the rear of the seat.. and looks like there's a block of styrofoam on the inside of the rear seat blocking off the channel. Also, the fan would have to go in from the front facing back to inside-out of the chair. This is because of a metal rod the connects the release/fold forward levers on either side that woud prevent mounting of a fan- oh and there's likeonly 1/8 of an inch etween the plastick shell and the internals so I believe it was intended for the fan to be inside.. I guess this was the "too much work" they were talking about. I couldn't completely removed the apostery because of time limited, needed to drive my annoyed girlfriend who thinks I'm spending to much time on the truck as opposed to other things. Well, I'll figure it out when I get back from NY next week.
