HMM, that is the 110 volt inverter plug not a 12 volt outlet. Most of the above no longer applies. Your description however points to a failed inverter module. The inverter is normally off. When you plug something into it the unit turns on. The fuse blows at that time because of a fault in the inverter. Replacing the module isn't that hard, easier than the above really. You remove the knee bolster from under the drivers side dash panel by removing the screws, Then remove the drivers side duct extension by removing the plastic push pin and sliding it off. Next you remove the wire connections from the module and the retainer nut from the bracket and the inverter slides off the upper pin and out. Reverse the process to install the replacement module. If the info is correct it is a GM #84181077
As for the wireless charger, it is sort of touchy in what it works with. However a dealer should have an inductive tester that slips into the slot and tests if the unit is operating. That test item is the only way I know of to test that module.
