'97 Outback rear accessory socket not working

The rear accessory socket in my '97 Outback is not working anymore, I checked the fuse, in the "fuse panel behind the instrument panel lower cover" but the fuse was fine. Does anyone know if there is another fuse somewhere ?

Thanks

Yep, under the hood

You mean in the main fuse panel ? not according to my manual and all fuses there are OK !
