I'm making progress on my 86. This week I repaced the fuel level and oil pressure senders, so all of my gauges are working. The last thing I need to fix on my project that is critical is my instrument illumination. Here is the story: When I turn on the illumination via the headlamp switch I do not get any instrument lights. The clock illumination goes out. Not dims, mind. Out. Turn off the headlight switch and it comes back on. I have voltage at the illumination fuse, and the voltage varies when I turn the headlamp switch. So the switch is good. I have power to the clock and cigarette lighter. Since gauges, radio, and lighter work, I have no indication that the grounding is poor. I do not have a working warning buzzer - though it WAS working recently. I have removed the radio, so there cannot be any issue with how I wired the radio. My best guess is that there is a problem with one of the circuits that connects to the dimmer switch. My first thought is to pull the radio/clock illumination relay, and see itfthat helps me narrow down the problem. According to my repair book, the relay is located "under l/h side of I/P, behind kick panel". The wiring diagram shows it wired to the harness at a point very close to the horn relay. I found the horn relay, but I don't see the illumination relay. Or anything that looks like one, nor do I see a socket for one. At this point I'm rather flummoxed. I CAN rewire the illumination directly, but I'd like to identify and fix the existing problem if possible. So I'm looking for suggestions as to what to try. And if anyone knows where the #&$#^$ illumination relay is, please let me know!

I am new to the her community and decided to start my first project, a ‘90 MJ. I have spent numerous hours trying to figure out why the driver side taillights are working but the passenger side isn’t. The previous owner butchered up the whole rear lighting harness. So I grabbed one off of another MJ and spliced them together hoping it would fix the issue. It did not change anything. I checked fuses and they are fine. Checked my ground wire on the rear driver side and it’s okay. Any other ideas to look into? Any information helps.

So, I'm not sure if this has been covered or done, but would it be fairly easy to rewire the turn signal/brake light combo such that the top segments of the tails light up exclusively as brake lights and the middle segments only light up when the turn signal/hazards are applied? I think this would be a cool idea and a way to stand out among other MJs. Also, I still plan to retain the dimmer parking light feature of both top and middle segments.

I need a domelight swich for my 87 comanche. If anyone could help me me in locating one. Thanks
