rear running lights not working

When i turn on my headlights at night my running tail lights DO NOT light up. The brake lights, turn signals, and reverse lights all work. I have pulled and checked every fuse under the dash and under the hood, and i can not see any OBVIOUS signs of blown fuses.I replaced the #3 fuse with no luck.
"Zac of all trades" had this exact problem.i never saw a resolution to his post

 

I spent a lot of time in this thread trying to help @tyoung05 solve this problem and he never followed through with the outcome.

Did you check the fuses with a meter or did you just look at them?
If you didn't use a meter it doesn't count.

The 10 amp TAIL Fuse supplies voltage to the Parking Lights, Tail Lights and the License Plate Lights.

 

I have replaced the fuse and have no change

 

Check the tail light relay by swapping it with another relay of the same type. If that doesn't correct it then it is time to get the volt ohm meter out and start looking for the wiring problem.

I replaced the fuse again and have resolved the problem.It took three fuses but that was the problem. Thank you
