Tail lamp not working
So the "Tail Lamp Failure" light came on recently and I discovered that my drivers side rear upper (above the reverse light) bulb was out. I changed the bulb with a spare bulb I had and it still wasn't working so I bought a new package of bulbs and still no go. I confirmed with a 12v source that the replacement bulbs are working, so I know it's not that.
I looked at the socket and wires with a flashlight and didn't see anything unusual. I also looked for a fuse that might control that one bulb (unlikely, I know), but came up with nothing.
