Hi,

I was helping my friend who had a puncture. Plugged the puncture and I plugged one of those cheap chinese air compressors into the 12V accessory power outlet and it worked for about 2 seconds then quit. Checked all the fuses and they all look good. I even looked in the manual and changed the fuse that is in the 12v accessory power outlet circuit and installed a new one (even though it looked good) and still no power. Also the 12v accessory power outlet that is in the trunk doesn't work either. What could be wrong? Is this going to be an expensive fix? I just want to run a GPS unit or my phone charger. Could the whole fuse block be bad?

Thanks in advance!
-Justin

The 1st thing I would do, would be to get a test light and check all the fuses..... You can't tell always by looking....

most of the time its the fuse. the other times is usually that the wire is knocked off the back either by just being loose and falling off or some one working behind the dash like installing a radio or something

...true, but that doesn't account for the rear 12v outlet not working also does it?

It would if the rear outlet already wasn't working and no one noticed until the front one went out.

Like I mentioned before the very 1st step is to verify ALL the fuses as good, the next step would be to access the frt socket and check for power & ground there ( as Dmac suggested) depending on what you find out would lead you to your next steps.......

If the all the fuses are good and there is no power at the frt socket, you are probably going to want to find a wiring diagram to help trace the circuit..................
