The power seats in my car stop working each and every time I turn off the ignition. After I drive for a few minutes, they start working again. It is both seats, so it can't be the switches or the motors. It must be something in the power feed to the switches, or the grounds.
Does anyone have a wiring diagram for the seats?

Thanks
