WHAT WOULD CAUSE ALL OF THE REAR LIGHTS NOT TO WORK?
MY REAR TURN SIGNAL LIGHTS, BACKUP LIGHTS, PARKING LIGHTS, TAG LIGHTS AND BRAKE LIGHTS DO NOT WORK.
For all of the light to go out I would look at the harness that heads towards the rear of the truck, it could have disconnected itself or you have a damaged harness.
yea what tennisshoes said
I viewed a diagram for the tail lights on my 2010 F-150. It appears all the rear lights function off a single shared ground. Use a multi- meter to check for current to the sockets. If present, look for a bad ground.
Disconnected/damaged wire harness or bad/broken ground wire
Did you find a fix for this? I'm having the same issue. Also a 2010 f150
