Backup lights not working

[Digangi]

I have a 2005 Expedition and just recently I noticed that the backup lights on both sides were not working. I cannot find in the manual what fuse would control the backup lights. Any suggestions on what I should check to try and fix the problem would be greatly appreciated. I am not sure if this is related or not but the other day the wife replaced the window sprayer/cleaner nozzle that was broken on the back upper brake light panel. I am thinking this is just a coincidence but I am not sure.

Check fuse #14 use a meter to check it don't just look at it

It was fuse #14. I replaced it and it worked for a while but it is blown again. Any suggestions on what else I can check?

There are other circuits that are on fuse #14 that could be the cause of the problem One is the temperature blend door actuator.
Do you have automatic or manual climate control?
Can you read and understand wiring diagrams.

I think the problem stems from a backup camera that I had installed previously. I have since disconnected the camera but the wires are still in the dash. The camera is activated when I throw the vehicle in reverse. The wiring is still hooked to the back up lights and I found the bare power wire in the dash. I covered it with electrical tape and I hope this solves the problem.

I would also check where you tapped into the backup lights to see if there is any corrosion, especially if you used a t-tap or something like that.

Seems like taping off the backup camera wires has solved the problem with the back up fuse.
