Does the AUX PWR 2 fuse, next to the steering wheel, go the outlets in the back? My 12v outlets in the 2nd row have no power. I checked over all the wiring and don't see anything wrong. The rear seat heater buttons on the same harness work fine. I replaced the AUX PWR 2 fuse and they still don't work. Is that the right fuse? If so, should I try replacing the actual cigarette lighter units next?

 

If all fuses are good, the socket has failed. I've seen it happen many times over many decades. Btw, oem sockets are outdated, time to upgrade. Many options available for socket replacement.

 

Ordered new cigarette lighters only to figure out AUX PWR under the hood was burnt to a crisp. Replaced it and the rear cigarette lighters now work. So problem solved but I don't know what AUX PWR 2 inside the cab is for.
