My reverse lights are coming on when I apply my brakes. What's going on and how can I fix it.

 

Does it also happen when you use a turn signal, left, right or both?
Do they come on when you turn on the parking lights?

 

Ok so here's the deal. When I press brake the reverse lights come on. When I turn my left turn signal everything works great. When I turn my right turn signal my turn signal blinks and so does both reverse lights.

 

You have a short in the circuit and it soinds like a good place to start looking is at the right taillight . Check the harness behind the taillight assy and check for dirt/ corrosion on the bulbs/sockets
Hopefully it's there, cause that's the easy fix.

 

OK - try this...
Remove the bulb for the right rear brake lights.
Now apply the brakes and see if the reverse lights go on.
If they do then it would appear there is a short in the wiring.
If they do NOT come on then it looks like the ground to the right rear light assembly is broken.

 

Ladies and gentleman thank you for all of your help. I fixed the problem. The wire rubbed against the metal were it goes into the light. Why oh why wouldn't they protect that area with either a big rubber grommet or foam or even sheathing on the wires. Thanks again.

 

The problem is back. What the...

 

LOL... aint electrical fun?

Usually a problem like this is caused by a faulty ground. Instead of the circuit grounding, the current flow "back-feeds" through the harness to another spot, in this case your reverse lights...
Id look at the frayed harness again and see if you got it all, and then check the ground to that leg of the wiring harness.
as suggested, also check for corrosion on the bulb sockets, that can cause this as well.

 

I will check tomorrow. Just frustrating because it comes and goes with no explanation. I did install a 7 way in the bed recently but that was all plug and play.

 

Well I couldn't wait until tomorrow. I took both lights apart and checked all bulbs for corrosion and checked all wires for frays. Nothing seems out of the usual. So...... now what? I think I will double check my 7 way connector in the bed.

 

Well, if it didnt do this BEFORE the 7 way is installed, Id say thats the problem. The short could also be in the trailer plug harness, those plug and play set-ups arent always assembled with quality in mind.
try a quick test, remove the plug&play harness and see if that corrects things.
Check your ground at the trailer plug itself as well.

 

The problem is I don't know when this all started I just noticed it when my father in law said something to me the other day. I apprieciate everyone's help. I sure hope I can solve it.

 

I've seen a lot of this type of problem caused by trailer connectors or their wiring. Your idea to check your new 7 pin in the bed is a good one. A wire can come loose and touch another inside the connector pretty easily. If you have another 7 pin under the back bumper, give it a check too. They like to scoop up slush and mud off the road and can end up with a short from one circuit to another.

 

Does anyone know where the ground is on tail light harness and where it attaches?

 

These help? I'd highly recommend downloading the repair manual so you can have a better look at the wiring diagrams. You can find the link sourcing it for free.







G106 - Trailer tow ground
G104 - Back up switch ground (I think I've got these labeled right)
