I seem to have a problem with the right rear turn signal. The front and rear turn signals work fine when the running or headlights are off. When I turn on the running or headlights, the right rear turn signal doesn't flash but the right front does. The left side works normally. I have LED bulbs in the tail lights only and I have tried a different brand of LED bulb in the tail lights as well as regular incandescent bulbs. i still have the same problem.

I've cleaned up the contact area where the bulb socket fits into the tail light as well.

The right rear does seem to be a little dimmer than the left rear bulb. I have run a jumper ground to the body and it doesn't help my initial problem. I replaced the front and rear light harnesses and I do have a new turn signal flasher as well.

Ideas?

Thanks

turn signal and brake lights are the same filiament I believe.
Are the brake lights working on that side and you just don't get lights for the turn signal?

Brake lights work.

Also, this problem repeats with 2 different manufacturer's LED bulbs and the factory incandescent bulbs. I replaced both sides with these 3 different bulbs when I was troubleshooting as well as only replacing the Passenger side bulb by itself and leaving the DS bulb alone.

Thanks

Did this problem suddenly develop or did it occur after something else was done?

Well, it's hard to say. I'm in the process of putting the car back together and I had tested the electrical a couple months ago and everything seemed fine.

I don't remember if I had the lights on and tried the turn signals, but I doubt that I did.

Thanks

Verify voltage to the bulb and ground when it is acting up. Pretty simple. you either have power and ground or you don't.

I I would suspect a ground problem

also inspect the bulb socket contact plate closely.
it may want to turn just a tick when seating the bulb, thereby causing each circuit to work independently, but not together.
or the socket itself may be just slightly deformed, loosing enough ground to act like the above sentence.

It almost always is.
Run a temp ground right from the socket to a know good ground

If the brake lights work then it is not a ground issue.

If you look at the wiring diagram, the wiring is the same for either all the way up to the steering column connector.
Something after the connector is messing with it.
The diagrams on my mopar don't go up the column to see where it goes from there.
Obviously part of it goes to the brake switch and the flasher, but I can't tell anymore from just that diagram.

MoparX for the win, I guess.

I really wasn't leaning toward a ground issue, although in a case like this it is usually the problem. I had run a jumper several times and it didn't help.

I pulled the tail light and wire wheeled and sanded all of the contact points including the studs that hold the housing into the car. After I put it back together all sorts of other weird shizzle started going on that hadn't happened before.

It's a brand new harness so that SHOULDN'T be a problem, but I decided to pull the bulb and push the wires and plastic tab up through the socket. Everything looked fine. I slid everything back and stuck a bulb in and now the brake, tail and turn signal all work as they should.

The thing that I did differently is that I pulled the wire and plastic disk down in the socket and then put the bulb in. Then I released the wiring and disc so that they were now against the base of the bulb.

Voodoo I guess.

We'll see how long it lasts.

Thanks Everybody

If the problem should recur I would go straight to the contact between the bulb case and socket (ground circuit). You may have a good ground on the socket but if it is not making a solid contact with the bulb base it would create your problem and be a potential head scratcher twocents beer
