LX570 ventilated seats in Land Cruiser

The two above posts together are making this thread kind of spicy. Haha

I just picked up a '10 LX and this was one of my first complaints coming from a Ford F150 where the butt cooling was much more effective. I talked with the local dealer and they stressed they are 'ventilated' vs fully cooled- meaning that there needs to be cold air below the fans. They recommended pushing more cold air toward the feet/floor and that that would increase/improve the effect.

Thanks for this tip! i've been frustrated by what felt like really inconsistent performance of the seats. Some days I feel the cool coming through, other days it's nothing. I'm looking forward to trying out pushing more cold air toward the floor.

I've noticed that I get a lot more airflow if I'm not putting my full weight against the rear seat back.
Makes me wonder if one of those oldschool taxi driver wooden bead seat things would be beneficial.

The heat index here in SC was 114 today. My 2016 LC’s AC doesn’t do a dang thing to cool my face, much less my seat actually cooling my rear end when it’s like this. I miss Freon.

Has anyone figured out an upgraded fan for this yet? I'm struggling to get stats for the existing fan so that I can research replacements. Hell, I would be open to using 2 fans (one for each duct), if it gave me more airflow.

Nothing figured but I've started looking through the service manual with the same goal in mind.

Since denismrzv bumped the thread, here's what the repair manual says. Contradicts some of the wisdom shared thus far!

3. SYSTEM OPERATION
This system operates the seat climate control blower located underneath the seat to provide airflow to the seat cushion and seatback. Airflow is warmed or cooled by the Peltier element in the seat climate control controller. The air that flows to the seat surface is distributed by passing through grooves that are provided on the seat pad surface.
The air is then dissipated throughout the seat surface through slab urethane foam and is discharged through the seat cover.

So: there is in fact a thermoelectric cooler inside the seat, it is not cooled solely by the front A/C as some have suggested.

The key bit to me is "dissipated through slab urethane foam", which no matter how hard the blower blows is not going to give a strong breeze on your undercarriage. It's fundamentally different from other brands that have seats constructed like a trampoline to let air through unobstructed.

If you have techstream, there's a whole page of info on the seatback temperature and blower settings.

FWIW I have a 2010 LX and honestly can't tell that any ventilation is going on, perforated leather is nice so you don't stick to it with shorts on but other than that not sure its worth it.

Same here. 2010. Can't feel s*** from the ventilation seats

Bringing this post up from the past, but I came across this randomly today and I'm curious if those who've dug into the seats would think this might work in our 200 series?

Very interesting, I found one for half the price and taking a flyer on it.

Here's another one for the GX460 on Etsy, shows how it might work.

"With Dust Deflection"

This was the one I ordered, had similar pictures. Reviews are mixed, so not holding my breath, but Amazon Prime for returns if needed. https://www.amazon.com/dp/B0DNFSJ5MS

I guess a simple look under the seats of my 2010 probably could have saved me the trouble, but definitely not close to the same size. Concept is interesting, and I'm sure someone could create this easily with a 3d printer in a size that would fit.

Just a thought, if you got it for a decent price, what do you think about trimming the sides like below? Is there room underneath the existing vent to slip it into place? I envision doing this, and blocking off the remaining air vent area, possibly drill/rivet it into place to keep it there. Or use a heat gun to soften the portion above the cut section and fold it over underneath to enable it to lock on without rivets?

Is the direction of the air flow with this in place positioned well enough to align with the seat fan?

The way it's setup it's way too small. I believe the cover is divided to direct air in different areas, but I think it's just one duct underneath there. To install I believe you would take off the cover and replace it with the unit. I could probably find a way to make it work/fit, but I think I'd look for one that's a better size first.

Part of the problem is the design that the LX seats rely on airflow down there in the first place, and if you leave HVAC on 'auto' that usually isn't where it directs air. On top of that I don't know that the fans are particularly strong to pull air up in the first place.

Comparing this to like a Ford or something where there appear to be much more powerful fans that regardless of airflow under the seat create enough of their own.
