2002 Olds Aurora.All interior lights are out. Found blown fuse.

Your Interior lights share a fuse with alot of other circuits and if I remember correctly the switches are built into the door latches.On some of the models the cigerette lighter is on the same circuit and if your element is bad it can short out,also you could check wiring between doors and body to see if any rubbed thru.

Do your power windows or mirrors work? I had similar problem where no interior lights would work, and only the driver window and mirror worked. Under the drivers seat about 6 inches behind where wires for the seat go into the carpet, there's a wire harness under the carpet. And in that harness of wires there's 4 wires clipped together and its wrapped in tape. Those wires are the serial cables that allow each door module to talk to eachother. Unplug it and look for corrosion. If there is, cut the plug out of there and re wire the wires together so that all wires touch together. Now try your lights and windows. It's a common problem, especially if you have a sunroof because the drain holes get plugged and water sits under the carpet causing corrosion.
