are you there
Already Tried: I HAVE CUT OUT THE FIVE PIN PLUG CONNECTOR TO THE REAR LIGHTS AND WIRE THE WIRE OF THE SAME COLOR BACK TOGETHER TO HOPE TO FIX THE BREAK LIGHT IN RIGHT REAR AND THE BACK UP LIGHT THAT WAS NOT WORKING. tHE RIGHT REAR AND BACK UP LIGHT STILL DO NOT WORK, I have tail lights in both rear lights, turn signals and full function in left rear tail lights.
I will send you digram please open it and et me know if this helps
I have a haynes repair manual but is not helping me out much.
TRY this factory wiring
Also take your test light and check for power right where it plugs in to lights the light boards on these will fail
were are the light boards
They should be right on the back of lens assembley
the bulb sockets
I have power there, I have swopped bulbs around to one side to the other side to make sure the bulb was good.
Check the ground on that socket
okay, that should be off a test connector on the right rear by frame.
I would check it at frame and also right at the bulb socket if you have power there then it only leave ground bulb or bad socket
I do have an extra wire that is light blue that was not in the five wire connector that i have no ideal were it goes, but has no power till the break lights should be on.
That should be for trailer brakes
oh okay, so that should be taped off then
I will have to go back outside and try to clean the ground again and see if this helps
OK let me know
why would just the tail lights work on the right rear, but not the break lights or back up lights on that side work?
Still leaves it to ground or socket if you have power there
okay, I will let you know what i find out.
I FOUND THE GROUND TO BE BAD ON RIGHT SIDE, REWIRED ALL GROUNDS TO LIGHTS, BINGO NO MORE PROBLEMS. Thanks a million.
