Volvo FM12 2013 Auxiliary Power Sockets Not Working

Help!

I have 3 auxiliary power sockets in my center console.

I’ve tested all 3 with my multimeter and only 1 works which is 24v.

Presumably 1 or 2 of these should be 12v.

Any ideas as to why the other the 2 are not working?

Ive located the internal fuse board (passenger footwell) but can’t see anything relating to these.

Any suggestions?

Thanks

Just to confirm I’ve now located the master fuse board and located a blown fuse for the 12v auxiliary power socket. However the other 24v socket still isn’t functioning.

More investigation me thinks…

and there was me wondering, why there seems to be more lorry fires being reported in recent times

check all the fuses are inserted correctly and not blown
