The driver’s heated seat turns on by it self. Then it won’t stay off for very long you can push the door mounted controls it will shut off for a couple of minutes then turns back on? I un hooked the switch on the door but it still turns on now you cant shut if off. Why does it do this and what can I do to fix it or disable it?
