I have a 2012 Chrysler Town & Country with heated second row stow-and-go seats. The seat heater for the driver-side second-row seat no longer works. When the button is pushed, it illuminates and there's a click from the dashboard. Within two seconds, there's another click from the dashboard and it turns back off completely. Both front seats and the passenger-side second-row seat work correctly. All the fuses seem to be good.
Where do I start diagnosing this?
