I just ran into this problem, and for my situation, it was the the rear hatch. there was a short (Open) in the housing for the rear latch assy. IF it's no bother to you to have ALL your electronics working, you can disconnect the harness, and be on your way, but in my situation, I had the rear hatch assymb. replaced and of course it's a dealer part, so they soaked me $200 just for the part, and it took only 30 min. to install. You might be able to find a perfectly good replacement at a jeep graveyard.

Has anyone or can anyone help me out. My moon/sun roof has a random glitch. On occasion when I go to close the slider, it will connect with the "Saftey" bar and re open half way. when that happens I have to push to close several times before it actually completely closes. any ideas?

I have changed the battery but there is still a strange ticking sound underneath the driver's side dash. The windows or AC will not work. Radio does work. It did this about 2 months ago when I started it....the lights went crazy blinking on and off, etc. We unplugged the battery for the night and that worked. However, it did not work this time w/the new battery. Any suggestions?

The lights are flashing on and off again too! Weird!

Just to update... I think the problem with my Jeep might actually be solved. The dealership took apart the entire dashboard and went over every connection. In doing so, they found "MULTIPLE" ground wires that were loose. They fixed them and I have had no problems since that correction has been made.

FYI: When the highly qualified mechanics at the dealership work on the electrical system of your vehicle,the first thing that they do is disconnect the battery. Realize that disconnecting the battery, and leaving the terminals off for at least an hour, essentially "re-boots" the electrical system. When this occurs, the electrical system will appear to function normally for a short period of time...up to 10 days.
 
Obviously, this leaves everyone with a false sense of success. Just something to think about.

Dear berger49,
 
I have a problem w/ '06 JGC where the every indicator in the entire instrument panel illuniates at once while driving. Driving performance is not affected. I am not positive what the gauges did. Did you see this problem? I am glad that the loose gnd repair fixed your problem.

Dear dyeomans,
 
What year is the JGC? I have an '06 and the headlights flash on and off rapidily in auto beam off mode. Are you talking about this problem with the headlights or something else. This is an infrequent occurance, however, it is dangerous. So far I can make it stop by switching to auto beam on.

dj,
 
i experienced random warning lights...typically the airbag light, the service engine light, and the traction control lights would flash on and off in addition to the tach and speedo bouncing all over the place while i was driving at a constant speed.

It sounds like a case of battery under load having low voltage, if you have a battery gauge you may notice instead of it pointing to close to 14 volts its closer to 12 volts as you drive, logically that would seem to be ok since its still in good range on gauge, but it indicates battery is near end of life, you have a 2006, have you replaced battery lately? if not, its near end of life. The jeep computer needs a stronger voltage than just over 12, and a weak input can cause what you describe. Go to a place that sells battery' and gives free battery checks. Sears, Pep Boys, etc. Auto parts stores are cheaper, most will check voltage, if you buy battery they will install labor free, Auto Zone does this right in parking lot, you don't need an auto parts store with mechanics bays. This is a quick free test at auto zone, try it, post if it was cause or not. I had similar problems about 2 weeks before battery finally died and left me stranded, new battery fixed all issues, i had noticed battery read about 12.5 volts on gauge before failure, now it reads about 13.7 with the battery i put in 5 months ago with no repeat of problems, knock on wood.
