Accessories Will Not Turn OFF

Power Accessory jack used to have power even with ignition off. Inside cabin Under hood main ignition fuse is good. Are there any fusible links in this circuit ?

Have good fuse at inside cabin fuse block. Good also at under hood fuse block.

Main ignition fuse is only for just that...

if you checked that the circuit to that power outlet is OK, including the wiring, maybe the jack itself is bad

disconnect it, then use jumper wires to the battery to see if it powers on.
