fuse location, 2003 Allegro 30DA

Where is fuse located. Our 2003 Allego 30 DA, RV--Cigarette lighter is used for gps power. The Behind dash retaining cup through which the wires pass and holds the lighter socket in place, came lose. It shorted out when attempting to refasten it to the front of dash lighter socket. Checked fuses through on top of dash access hole and all fuses were functioning there.
Thank you
