Drivers seat heat button, will not turn back off heat ?
So is it questionable whether the button turn the heat off or not?
Can’t diagnose the problem from the internet. Electrical problems are pretty straightforward when you have an electrical diagram, a volt-ohm meter and the car in front of you. Find a local independent repair shop and expect to pay them for their time finding the cause.
Is the problem that you can turn the driver’s seat heat on, and it heats the seat ok, but then you can’t turn it off when you prefer it to be unheated? When you first start the car does it remember which mode it was in , heated or unheated? Or does it always start in the unheated mode?
