The heated drivers seat turns on and off on its own. You can turn it off but it will come right back on.

Good afternoon.

It is possible the switch is bad or the controller. I will attach a diagram of the system for you.

There is a memory module that controls it as well.

I would have someone with a scan tool monitor the system to see if it is working correctly.
