    Folks, is getting hot here again and I remember how hot the 3rd row seats were last year and decided to do something about it.

    Bought two clip on fans, USB powered with single 18650 Li-Ion cell backup from Amazon. Clips onto the jump seat headrest right in between the seats. USB cable runs along side of seat and under the floor mat to the USB plug in the center.

    Idea is to use them to bring some air conditioned air from the main cabin rearwards. Going to see if it is better for them to both blow back, or one go back and another forward.

    interesting... but wouldn't it get quite annoying having the fan blow directly onto the head? Maybe should point it to the side?

    Possibly, but my kids are not that tall yet and the top of the heads are below the top of the seat so it won't be directly on their heads.
    Going to take a longish drive tomorrow, we'll see how well it works.

    I have those exact fans, but I have 4 of them. 2 to draw cool air to the back, and 2 to have cool air to their faces (if they want it). That system seems to keep my kids placated if I put them back there! (Especially during the hot Texas summer)

    Ontario summers are not quite as hot as Texas summers, but is good to know that adding 2 more fans will make it work there too.

    Did you tint your hatch glass? I have 3M crystalline 70 on it and it helps a lot.

    You'd think the rear seat option would include HVAC ducting? How difficult can that be to add.

    We purchased the OEM rear window shade from Tesla's website, and that has made a nice difference for the temp back there - they claim it blocks something like 60% of thermal load, and my little guys report it helping a lot.

    If the third row is occupied, be sure to disable recirc. Airflow in the car is front to back, outlets are by the lights in the sides of the third row and recirc doesn't force air back that direction.

    Trip was a success. Outside temp was about 30C and the kids did not complaint at all with the fans on for over 1.5 hrs. I wish Tesla would have this built in so it looks better. It is definitely functional.

    Super hot day here in Toronto, found another use for the clip on fan (no one on 3rd row seat)

    If the fans have LED lights, at night, the car behind would see a pair lighted eyes looking at him from the rear window....
