The 12-volt aux power sockets do not work and checked fuses---what could be the problem?

Which engine ?

Either the fuse is popped or the power point is defective. Take a 12 volt test light (avail from any auto parts store for about $4) and touch the center of the socket it should light the 12 volt test light, make sure you have a good ground or the test will be invalid. If the socket shows no power then refer to the owners manual and locate the fuse for it, if that is ok you need the power point socket replaced. If you do not have an owners manual you can download one here.

Check pin number 16 of the OBD2 connector under the dash, it should have 12 volts, if not check the fuse box diagrams for the source of the connectors B+ 12 volts.

Hi, you have a 15 amp fuse to run all 3 sockets. Total peak power available without burning the fuse is 15x12=180 watts peak. Please let me know if you have more questions.

that would be the fuse for the other power socket/12 volt outlet (cigarette lighter) in the vehicle.

there are two auxillary power sockets. The console aux power socket is protected by fuse #4 in the battery junction box. The second aux socket located in the rear is protected by fuse #1 in the battery junction box. Both fuses are 20 amp fuses. The battery junction box is the fuse box located under the hood, usually on the driver side.

you likely have a blown fuse. look in your owner manual for the fuse location and change it with a new one of the same amperage. In the unlikely event that the fuse is not the problem, then the problem is that the aux. outlet itself needs to be changed.

You are correct. There is a fuse in the underhood fuse/relay compartment that powers up the pin. It is one of the larger fuses and should be labeled as "AUX". Also check that the power wire is connected to the AUX bolt terminal. They shipped from the factory disconnected and the cable was zip-tied to something below the fuse box.

Could just be the socket itself. The single wire connected on the back tends to fall off on some vehicles. You can just pull out the socket.

check all fuses for a bad one or the plug could be burt out had to replace mine its a cheap part
