Can someone confirm heated/cooled seats only blow on between your legs/bum?

[MrTrendizzle]

Hey.  

Recently cracking up the AC and running the seats on cold i've noticed i only feel a fable woft of air between my thighs when sitting in my car. I'm unsure but when i first got the car it felt like the back of the seat also was cooled/heated could someone please confirm if your seats cool your bum or also cool your back please.  

If it is the back also then does anyone know where the fuse is located to check please.

I thought it cooled and heated the back of the seat also.

I've just checked under my seat to confirm the fans are spinning. I watched the video Texas linked and what i've done is lifted the back of the rear mats and tucked them under the rear seats to block the vent and keeping all the cold air under the seat.  

If i listen to the back of my seat i can hear a fan and feel a very small amount of air come through the seats but the majority of the air is coming from between my legs right at the front of the seats.  

Bit of a shame really. I was really looking forward to ice cold seats in this heatwave but i'll take what i can get and enjoy the AC while i can. :)

Maybe wear some really wide leg shorts?   😊

The design is compromised so there isn't as much air at the seat back compared to the seat base and then once you sit in it your back blocks all the air so you get very little benefit.

Is it the design or is it something i could adjust/fix? Last time i used the cooling on the seats was during winter and it felt really icy cold on both my bum and back. I guess with the video Texas linked it makes sense that it's ambient temps so have sorted the AC duct under the seat. Would love a little cooler air on my back tho.

I'm wondering if it's worthwhile to poke each hole, but very carefully, to possibly clear any blockages which are quite probably there. After all our cars are quite old and have had many a sweaty bum/back sat in them and cleaned with probably a inappropriate cleaner. I must test mine out come to think of it.

I think a good strong vacuum might be better than poking sharp objects into the top quality perforated Lexus leather 😳

[Mr Vlad]

Yes, I didn't think of that. Note I did state 'carefully'. Yes a good vacuuming with one of those brush nozzle attachments.

The only Lexus that has cooled seats is the LS (with certain options depending on age). You have ventilated seats, so to get the best benefit you should put your AC on and direct it to your feet so the cold air goes under the seat where the fans draw it up.

On IS250 seats are not cooled, just ventilated - so it uses whatever air it could get from the cabin for cooling effect. On other models there is direct A/C line going to the seat and it is more noticeable. As for back ventilation it is as others said - technically it ventilates as there is little channel going into the back, but no dedicated fan and when you not sitting on it you can feel just a little bit of air coming out, but it is so weak that it is pretty much useless once you sitting.
