Seats Not Cooling
My 2010 Lariat has the heated/cooled front seats but when i turn the cool seat button I hear the fan in the seat but it doesn't get any cooler. It was working like the seat was ice. Now fan but not cold. Anyone else having this problem? If so how can I fix it?

It's a bi-metallic cooling system, so it may be an electrical short. (there's no AC ducted to the seat)

It's just a fan that pulls air from under the seat, whatever the air temp is under the seat is what your going to get, I thought the same thing, I got my 2010 in late 2009 getting into the cooler months, then when summer started to hit here in the Florida Keys I didn't think it was working until I got under the seat and took a look.

In a nutshell, if you run a current across the apparatus one way, it heats; if you run it the other way, it cools. It's a rather neat application of engineering ingenuity! I was surprised when my mechanic told me they had used it in the seats (I didn't think the technology had become that cheap yet).

not questioning your mechanic but....I don't understand this, when cooling, the fan pulls air from under the seat and blows it out the perforated holes in it, whatever the air temp is under the seat is what you get (from what I've experienced). When heating the fan doesn't come on at all, there is a heating element in the seat.

Ya he is right, google it, neat read. It only works for like 20-30 min i think, it wont stay cold all day. I may have the time wrong, i read about it a long time ago and cant remember.
