I have read various responses to this issue and have not been able to solve mine, which is why I added my own post:
1. I have tried turning the seats on while the engine is on, while I am out and about driving, and while in idle before leaving the garage. The only difference I see between when the engine is not on and when it is is that, instead of the entire button being grayed out as it is when the engine is not on, only the “hi” and “lo” choices are grayed out when the engine is on. I can push the buttons, but they do not turn the heaters on or change color in any way.
2. The rear seat heater buttons also do not light up when pressed to indicate that the heaters are on, either hi or lo. I have not seen this addressed elsewhere either.
3. I have tried going through the screen various ways to get to the seat controls and have had no luck in any instance.
Is anyone aware of any setting that would lock or turn of heated seats, whether it be to conserve battery life,etc? This appears to be the only function in the car that doesn’t work (the “seat controls” screen also in less a rear seat headrest folding button, and that works fine - headrests in the3rd row automatically fold when pressed.
