2014 Sienna cigarette lighter/ aux power port is dead. Lower port near floorboard is hot but upper (easy to access) port is dead. How difficult is this to replace? (already checked fuses and also chargers etc in other cars and they work fine. It's the port not the appliances to be operated. Approximate cost from dealer or will an after market socket suffice? Finally, will the cap to cover unoccupied port be included with OEM replacement from dealer parts?
