1 year ago I captured the appropriate CAN frames with the factory buttons connected and was able to control the seats by sending frames myself.
High, Medium, Low, Off
124 is request -- goes back to 00 00 00 00 00 00 00 00 when no buttons are pressed 125 is state -- starts as 02 02 00 00 00 00 00 00 when the vehicle starts and the seats are off

I have shared this info with KSPIV and they're working on an update to make the seats work in the UX.
The icons are there in the A/C control screen, but they don't respond to touches (don't turn blue like the other icons) and the seats do not heat / cool.
