I never own seats that cool and heat until I bought my 2012 RX, and was wondering how Lexus cools a seat......Fans??

Also, I had it on cool today, and seems to cool the back of the seat only, is this normal?

Cheers!

Yes, it is just fans. There is no "cooling" actually built into the seats. Ventilated seats would be more accurate actually.

The amount of airflow coming out of the seats is not dramatic by any means.
If you really want to feel it, you need to put your a/c on and set air-flow controls to bi-level ( dash vents & floor vents on).
In this way, the fans will pull the cool air off the floor and pull it up through the seats.
The "cooling" effect will be much better this way.
Good thing to try in the summer months.

Yup. In the brochure they are heated/ventilated seats. FWIW Lexus is known as having the best functioning ventilated seats on the market.

I am not sure about the ventilated seats as we have not tried them out as yet, but I can tell you that the GM heated seats in my Cadillac CTS are dramatically better that either our 2001 or 2011 RX. On high you can barely feel the heat.

The old heated seats were heated differently not by air coming through the perforations. The original RX had the hottest heated seats. The second generation worked in a similar way but according to my sons, didn't get as hot. The third generation uses air.

Someone made a post about this on how to maximize the cool air. Too lazy to search for it at this time.

I just got the ball rolling on this one. Donmatt refined and perfected it.

Next project is to see how many parts are interchangeable with the 2013 model..........
