After I turn off my vehicle, without being depressed, my REST button turns on- recycling the air inside, and does not turn off by depressing/pushing the button. Unlatched negative terminal battery line, waited about 15-20minutes, reconnected, and same result proceeded. Many assistance would be greatly appreciated. Possibly a fuse location so I can keep my battery connected without being drained from REST fan blower motor running while my engine isn't engaged.
