03 aux outlet problems

[retired0402]

I have a '03 ext.cab with both of the aux power outlets have quit working. I replaced the 20 Amp fuse under the hood, and saw the secondary aux. power fuse behind the drivers door, (manual says it is not used(?)) but they still are dead? Any suggestions?

A tech , past fuses , nothing you can do besides get schematics and if no experience in electrical it will be difficult for you

If you get a subscription to Alldata, follow the circuit schematic in reverse with a test light and multimeter. That should give you an idea of whete the problem lies
