07 Pontiac G6 GT....Replaced w New #20 Fuse Located rear drivers side fuse box, but still no power to 12v located under A/C and in Center Console. Trying to trouble shoot. Any idea's?

You are talking about the one in the trunk? Three fuse blocks in the car. For the Cig/Aux - it's the block in the trunk (drivers side). It's a 20 amp fuse.

If so I would get a multi meter and check the wires right at the lighter plug. If the wires have both power and ground you probably need to replace the plug. If only power and no ground trace ground wire back to ground and re secure it.

Which is the ground would it be black , blue, green, wire?

O6 G6, the back fuse box in the trunk has no power to it.. I used my tester .. all dash board lights , and the light also turns inside but only the one in the front. The light in the back inside the car and the radio no power. Cig/ lighter has power.. and it starts fine.. And all fuses under the hood and passenger side fuse box has power. On the one in the trunk doesn't.
