Hi I have a 2003 Chevy Silverado and I was blowing up a pool float in my truck with a tire inflator and now my 12volt outlet on the passenger side is not working I checked all the fuses but they all seem to be fine not sure what to do if the fuses are fine and all other outlets work
Recheck the Auxiliary Power Fuse (20 amp) in the underhood fuse box.
Maybe grab a test light and check for power on both test tabs of the fuse.
If it's good pull out the fuse and check for damage to the sockets the fuse plugs into.
If all that's good you'll have to check the power and ground on the wiring connector that plugs into the back of the Auxiliary Power Outlet.

Perhaps if that all checks out good, and you looked at the fuses but didn't swap any out to test, maybe try that.
Sometimes it's not visually obvious the fuse has blown.

Get a wiring diagram and trace out the circuitry until you find the fault.
