1995 Jeep Other Repair Question
Models changed headliner - electrical/securi
1995 Other Jeep Models V8 Four Wheel Drive Automatic 175500 miles
I have a Jeep Grand Cherokee Limited 5.2L and I just took out the headliner and replaced it. When I was reinstalling the headliner, everything was fine until I was reconnecting the overhead console. I reconnected the first part closest to the rear-view mirror and then reconnected the rear section that sits directly above that little half dome thing. It was fine until I was sliding the console back on and then the lights started dimming and there is a rapid clicking from the fuse box area on the passenger side. I also noticed that I don't seem to have proper power to the entire section where the radio is as well. I disconnected the battery and left it for 30 minutes before reconnecting it but it still has the same problems. I did take the headliner back out to check for any shorts in the wire and don't find any problems or see any fuses blown. Any help would be greatly appreciated as I need to sell my car in time to pay my rent! Thanks!
** More Details **
When you open the door: It has the rapid clicking noise, the door lights are at the normal brightness, the overhead console lights do not work and the power does not visibly come on to the radio or anything in that section
With the key in the 'ON' position: the lights and bells in the dash sound but like the batteries are going low then go out, the door lights and the radio console area lights flash on and off and the compass and thermometer seem to be working fine
When it is started: the lights in the door and radio area flash but the fan will come on to make the a/c or heat work, all of the exterior lights work except the overhead console, the door lights stay bright when the door is open but stops when the door shuts, and the interior light switch makes the lights come on except in the overhead console but it causes the fan to slow down a bit until you turn it back off...
I opened the panel in the glove compartment and found that the relay on the row nearest the opening on the right is the cause of the clicking... I went to the Jeep dealership and got a new relay and it still does the same thing...
All since headliner install? unplug everything that has to do with the headliner and see what happens.Are they the same overhead lights and upper console that was in the vehicle before or are they new with the headliner?Did you check the fuses with a test light?

If all plugs were plugged into the right recepticles, then look for any chaffed wires, especially power wires. Also, be sure all plugs are firmly seated! Unplug and replug all of them. I assume all worked OK b4 you did the headliner?
Yes, all of the lights worked fine before I replaced the headliner. Everything only plugs into one place and wouldn't fit into another spot. I did completely remove the headliner again and checked for any shorts. Re-taped any spots I felt could be questionable. The problem is when I plug in the one above that little dome on the side of the overhead console that is closest to the middle of the car. When you plug it in that's when there is a problem. I traced the clicking that it causes to a relay under the glove compartment and replaced it with a new relay. Still the same problem. I have also pulled and checked every single fuse but none are broken. Maybe if I knew what that set of wires controls that causes the clicking we can get to the bottom of this...
Did the new headliner come with new electronics, or did you transfer them from the old one? If new, try replacing the troubled part with your old one...
Here's what I did: I unscrewed and disconnected the visors, the three little handles that are on the front passenger and rear seating areas, unscrewed and disconnected the overhead console, unscrewed and disconnected the rear light and then unsnapped the little plastic side panels that hold up the headliner. Then I slid it out the back door. I did not replace any electrical parts at all.
That's why I asked what that little computer chip is for that is where the problem seems to be coming from or if you know what that relay controls. I cannot find a diagram anywhere for that set of relays and don't understand why that particular wiring bundle affects such a strange combination of things... I can't imagine that I'm the only person that's had this issue but also cannot find any info. on the subject...
The keyless entry module is in the dome light, the relay center is in the glove box, here's the layout of that.
It seems maybe a ground wire is not properly grounded?
Thanks! That makes sense that the lights would be having difficulty working if there is a short in that somewhere... But the part that perplexes me is that if that relay is for the illuminated entry lights, why are there no light wires running from the actual overhead console lights to that particular switch... I completely took apart the overhead console and took off the old electrical tape and put on new tape. The little circuit board that it plugs into looks fine. I would test it but don't know how... Here's some pics of the wiring... Do you think it could have blown the little circuit board?
Have a close look at the board with a good magnifier, you may find a crack in it, and might be able to resolder the joint/lines back together. Us a piece of wire to bridge any cracks instead of globbing solder on it!Pay particular attention to the plug/prong area.
