I've got a 2002 4.7 QuadCab 4x4. I recently noticed that my driver's side rear tail light has stopped working, as well as the driver's side rear license plate light. The turn-signal and brake lights still work on that side. I replaced the bulb, still is not working. I'm assuming that there is a broken wire somewhere? Not sure how this would have happened, but let me know if you have any ideas

Thanks

 

Check the coupler at the light to make sure all the connections are tight. I had a problem with my front left turn signal.

The indicator was flashing quick. I thought it was one of the bulbs but when I replaced it the light would still not work. After some playing with the wiring I noticed the 90 degree coupler was not fully plugged into the wires. Not really sure about your license plate light though but follow the wires back and see if you can see anything.
