    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.

    berger,

    Sounds like the same thing. Both cars are 2006. So far, I have only seen this problem a few times. I will remember the ground connection issue. BTW, my battery is new. Please post again should your problem return.

    Regards,

    We are having the exact same problems. What if any, did you find out about the vehicle dying. The vehicle will turn off with no warning. We have also had some a/c & heating work performed by the dealer...so did not fix the problem. The engine light is on with crazy readings and just today the indicator for check guages displayed.

    OK, here is a new one that I think is more common. 2006 JGC. The power window will not completely close. When you close the window, it goes all the way to the top, then reverses and comes part of the way back down and then stops. Any ideas?

    Thanks,

    tuggajb,

    Thanks, any idea where it is located? I could not find it in the 2 access panels. Maybe it is in the door???

    Thanks,

    upon further reading the motors on the window of that year use current load to reverse if you have a binding in the window or tracks could cause the motor to reverse as a safety move (to prevent injury to people between the window and frame of the door ) check for binding and if not need new motor

    One of the switches to open the window on the master switch panel is broken.
    Dealer suggest to me to replace the entire master switch panel to solve the problem but this is a costly event.

    Do you know whether I'm able to replace only the switch and if not If I need to get the entire master switch panel where I can buy this (used) so I can install it myself.

    Any help is welcome as can't open the drivers window at the moment

    Regards

    John

    John: I've found Ebay to be a great place to find replacement parts for both of my Jeep GC's.
    If you can't find the part on Ebay, Auto Zone carries a great deal of electrical parts for the vehicle. Generally, you can perform an internet search on AutoZone.com to check for availability before visiting the store.
    I'm sure that I don't have to tell you that dealership repair shops tend to focus more on gouging the customer, than on doing the CORRECT job at the right price. Not everyone has access to a mechanic; I suppose that I'm lucky in the fact that there is a small vehicle mechanic's shop in the small city that I reside, and I tend to leave jobs like this to him. This may not be a difficult fix, but a sharp mechanic could probably do the job in short work, and do it right. To determine the difficulty of the job, you may want to search YouTube; there are many videos on YouTube, that range from the simple to the more difficult jobs.

    Hi tuggajb,

    One thing I should have mentioned. The work around is to roll the window up while keeping my finger activating the window switch. When the window reaches the top, I continuing holding my finger on the switch for several seconds until I hear a slight click. Then the window stays in the proper position.

    yep sounds as if the window motor is going bad draws to much power try and spray silicone lube in the window channels see if that helps reduce the drag
