Right turn signal blinking BOTH rear signal lights

Hey all,

When I hit the signal to turn left, both rear signal lights go off. (like hazards are on)

This only happens to the left, not the right.

Funny thing is, once I move the lever back and forth (like keying the high beams) the right signal stops and the left continues...

Anyone else had this happen?

Thanks

I haven't, I would almost say it is a wiring problem made by someone trying to add trailer lights or something... but maybe not. Get familiar with your electronics that control the circuits, see where the apex of the issue might lie. Something that controls multiple functions for lights, like the switches in the steering column or something.

I have an '88 and '01 XJ, so I might not be much help. But I might be able to find some diagrams if you need them.

Leaning towards the hazard switch...

I think the culprit lies in the hazard switch or the high beams, something in that area is completing the circut to light both lights, maybe the turn signal switch is just on it's way out...

Strange how it only lights up the rear tho come to think of it, I may have to recheck that.

Well, that could very well be. Just depends how the wires are bundled in that area... or how the switch is designed. With that mountain of electrical possibilities, I usually start by looking at the small signs that might give it away... something else not working... a movable joint where the wires run that is moving differently. Could be somewhere that has a joint, like the steering column, has cut the 2 insulators of the wires and touches them together. Start with obvious stuff though, like switches.

Three possibilities where the problem is. (in most likely to least likely order)
1. Turn signal switch/stick thing. Known to go bad and cause weird electrical problems.
2. T-junction under the spare tire mount where the wires split into each individual sides. The problem could be a short there, or someone may have buggered up the wiring trying to install trailer lights
3. Corrosion or a short at the sockets themselves.

Most of the time I find its corrosion in the light bulb socket. Remove the bulbs and carefully clean the sockets. Use some light bulb grease with new HD bulbs and see what happens. Bet your extra blinker problem will vanish.

Check your tail light bulb sockets for corrosion. My old Buick would do this and it was the sockets themselves. Easy fix just frustrating troubleshooting.

It's the directional switch assembly in the steering column. It's a relatively cheap part that requires removal of the steering wheel to replace.

If you have tilt wheel, you will need a special tool to remove the lock ring above the switch. While you have it apart make sure the torx head bolts holding the tilt mechanism in place are tight too.

Thanks Kaus, that is what I thought too, it seems to be there...

By the way, anyone have info on the HD bulbs? That would be a great idea.

And sorry for the late post, my e-mail notify seems to be on the fritz...
