Hello! I am having a very strange issue with the interior lighting in my 2011 6.2L F250 Crewcab; the map lights do not properly function.

The maplights and rear switch lights previously worked flawlessly, however after I changed my maplight bulbs, I cannot activate the rear switch lights, and clicking the front maplights doesn't work, I know it's not bad bulbs, because they activate properly when opening a door, or the driver's domelight switch is activated.

I have no other electrical problems, and I don't believe I have any bad fuses, I have already tested them, my only theory is that when I was changing my maplight bulbs I may have shorted something, but I can't see anything currently shorted, and I can't find a bad fuse.

I need help! Any advice would be very welcome!

 

It ended up being Fuse #4 in the interior fusebox, I had swore I had checked that fuse, but that was all that the problem was! I just fixed it today.
