02 TJ turn signals stay on steady

A few months ago the turn signals on my 2002 TJ began staying on steady after sitting in a right or left turn lane for a few minutes. It is always after being on for awhile that they "stick." It doesn't make a difference which way I am turning. If I let the switch cool down (like between turns 5-10 minutes apart) the signal cycles normally again for a minute or two. The only change to the electrical system is the addition of hitch lights specifically designed for the TJ factory connectors.

If you mean the turn signal light stays on when you step on the brake after completing a turn, that is a lazy turn signal switch that isn't quite returning all the way back to center after completing a turn. See if nudging the turn signal stalk a little more torwards center after completing a turn helps that issue.

If that's not quite the case, still try slightly moving the turn signal stalk up or down and see if the problem goes away. If it does, that is still a turn signal switch problem that can be cured by replacing the switch.

It will also do that when the flasher relay module starts to go. It's easy to replace under the steering column

The signal stays on while I am sitting still, brake on or off. If I return the lever to neutral then signal again it blinks for a moment or two then sticks again. After a couple of repetitions of this procedure the signal is on solid no matter what I do. I have removed the covers for the steering--is the black box the lever goes into the signal switch?

Yep, only a couple screws hold it in place. I can replace the the turn signal switch in < 5 minutes from start to finish, it's an easy job. Even my local Autozone got me the right replacement switch which surprised me when it turned out to be the OE switch. Down to the initials of the QA inspector scribbled onto its little blue sticker.

still not working

I replaced the switch--problem persists with the only change being thatthe signal arrow doesn't stay lit but goes dark. Ideas? Where can I find a readable wiring diagram or better yet goods labeled pics of the components?

Did you unplug the hitch plug from the harness to see if it makes a difference?
Since you already replaced the switch, the hitch harness or the flasher sound like they may be the problem.

It could be if you were trailering it was enough of an additional load on the flasher that it damaged it, also.

If you already replaced the switch, you missed the relay by a smidgen. It sits just to the right of the hazard button, under the column top cover. Little black box, bout the size of a Bosch relay.

Flasher relay mod.

Okay Shelby I'll try that next, thanks. BTW: I got the switch online at rockauto.com for $50. Looks and fits exactly like the OEM. they shipped fast via USPS--I'll see how they do with the flasher relay....
