I have the next question because it just happened. I have a F150 2001 and every exterior light is working except my taillamps? Can someone help me with it? I think it is a fuse but I can't find anything about it in the manual.

Please help me asap.

Thanks in advance,

Frans

 

Pull the lights out. Turn on the signal or have someone hold the brakes, while you use a test light to see if you are getting power. Ground to the truck not the harness, I have seen fords have problems with the grounding of the tailights before.
