Modify or disable heated/ventilated seat?

[LongJoSilver]

I dislike how warm the seat bottom is compared to the backrest in the Rivian. In our BMW, we can adjust the distribution of heat between the seat bottom and backrest independently (see picture below). If Rivian were to do this with a software upgrade, it would require the circuits to be independently wired and I'm not sure if that's true or not.

While I hope and wait for an update that may never happen, I'd like to try and manually disconnect the bottom seat heater. Has anyone played around with the seat wiring and know how to do this? Has anyone seen a seat wiring diagram?

The alternative software "fix" for this would be to allow simultaneous ventilation and heating which I think would also address my complaint. My far fetched idea here would be to use a relay to turn on the ventilation when the seat heater is activated but that may be a bit ambitious.

The only seat teardown I could find is here, but isn't detailed enough to help me out: .

Let me know if you have any other tips and if you like this idea, please vote for it here: https://riviansoftware.canny.io/wish/p/seat-heating-distribution-backrest-vs-bottom

My guess is the back just connects to the bottom via some type of plug. To accomplish what you want would require the two be separated. Doubtful that it will ever happen. Rivian is trying to decrease manufacturing costs not increase it.
