Turn signals, horn, interior lights, rear wiper... DRIVING ME CRAZY!
2007 Rubicon, 2 door, auto. I've only owned it for a few months now but the electrical gremlins are in full force.
Preface: I have replaced all turn signal bulbs, side marker lights, and reverse lights with brand new standard incandescent bulbs for troubleshooting. I have replaced the turn signal stalk assembly with an OEM part. I have replaced one of the 15a turn signal fuses.
Where to start? The symptoms differ based on whether or not you have the running lights turned on.
Running lights OFF: the turn signals will work normally 90% of the time, but they will occasionally start to hyper flash. The front and rears both illuminate at this time, they just hyper flash. The only way to get them to stop hyper flashing is to shut the Jeep off and restart it. Hazard lights operate normally both before and after hyper flashing begins.
Running lights ON: the turn signals will blink 8 times and on the 9th time, it will start to hyper flash. The difference here is that the front turn signals won't illuminate at all (even as DRL) after one side starts to hyper flash. Rear turn signals illuminate even after the front signals stop, but they still hyper flash. Hazard lights will work normally until the hyper flashing begins, at which point the rears will blink at normal speed, but the fronts still won't illuminate. Again, the only way to return them to normal is cycle power via the key.
Other issues, not as pressing, but still annoying and possibly related:
The horn: it worked when I got the Jeep but mysteriously stopped working. I checked both fuses and they were okay. I have not checked the switch/contacts behind the airbag yet. The clockspring recall repair was performed by the dealer prior to my ownership.
Interior lights: the dome light occasionally will not shut off when all the doors are shut. The only way to get it to turn off is to turn the switch all the way back on the stalk. It's a 50/50 chance if it wants to turn off properly. The DOOR message does not display on the gauge cluster like it does when a door is not fully shut.
Rear wiper: the rear wiper will stop mid cycle and may or may not begin working after you turn the jeep off and restart it. This is on the other column stalk obviously, but since they are jumpered together I figured it would be worth mentioning, as they could be related.
I guess I'm hoping for something fairly simple. Maybe a common ground that has corroded, or a spot where the wires wear through and short out, like the XJ wires do where it passes from the door into the cabin. I'm fairly new to JK ownership so I'm not keen on the common issues. What I'm hoping it ISN'T is the damn TIPM. Any help would be greatly appreciated!
