i have a question about the seats. How cool are they suppose to get? Is there anything else you do but tur the dial to cool temperature ? Mine is a 2013 F sport. It feels a little cool but never seems to get real cool like a friend of mines Acura does. Maybe I am expecting more than I am getting. Never had ac seats before. Is there a way for me to check like when you stick a temp gage in ac vent? Thanks for any help.

Aspect

Not AC seats, just ventilated. There's a fan blowing air through the seat but it's not connected to the AC

Just so I am clear the dial that is on the console that reads red numbers on the left of it and blue numbers on the right as you turn is not for cooling? It get very hot on the red numbers. Does it just heat? No cool? The build list says it has heat and cool seats

Aspect

Just heated. The numbers for the blue side are just fan speeds at that point. If your ac is on in your cabin for a while it'll start sucking that cool air as well and make it cooler.

Aspect is correct, ventilated seats bring the floor air through the seats to...your seats.

Be aware that "Auto" A/C usually brings cold air to the dash vents in the summer.
Try tapping the A/C Mode button once to direct air flow to both the dash and floor vents.
The "Auto" button light will go out but it is still on your temp. Now there is more cold air
flowing under the seats to be percolated up to you.

A/C compressors take a lot of energy and bring down your MPG's. The two fans in each
front seat use a negligible amount and can add a bit of comfort cheaply. Lexus LS seats
are actually cooled BTW.

Last point is F-Sport specific. Your seats are formed a bit differently than most Lexus foam
filled seats. The perforated seat holes go through the leather and the foam. Early versions
of the F-S seats did not even offer ventilation and now that they do it seems that body weight
does distort the "tubes" and limits the flow.
