Jeep Grand Cherokee Electrical Problems



  • To anyone having flickering headlights/interior lights issues - I have found a solution!! I had this problem for 3 years and finally found a specialist that immediately knew what to do. It's your light switch/turn signal. You just need it replaced. It cost me only $200.
  • I have same exact problem now for past few months on 2005 Jeep Grand Cherokee .... Thinking it might be a fuse also but not sure ...??

    ((And also in addition to previous posts my jeep's whole electrical system instrument panel used to flicker on and off very crazily for no reason but when I would turn the jeep off and back on the instrument panel would light up normal . Took it to dealership and they never could find a problem and now it has not happened luckily anymore in the past couplen years ....))
  • For several mornings, I have been woken up at 3 am or so for the alarm in my Jeep Cherokee going off randomly. I thought that if I pulled the fuse that it would stop. It did not. I pulled one of the other fuses related to the security no avail as a matter of fact this morning when I went to start it to go to work. It would not start. When I put the 2 fuses back in it started just fine. What in the wprld could be causing this and what can I do?
  • I am guessing maybe a low battery.

    I've had similar problems. I got the car used (180,000 miles now) and I don't know how many owners before me, but I didn't get a door remote to lock and unlock the doors. Have to use the key. I found that if I lock the doors with the switch inside, shut the door and leave, the alarm goes off within 5 minutes. Have to use the key in the driver door to reset the alarm. Also had left the dome light on and the battery died. I couldn't get it started via jumper cables....lights just kept flickering and the ignition clicked....until I thought about resetting the alarm with the key in the door....and it started fine. It's inconvenient but door reset seems to solve the problem for me. Hope it helps.
  • I know this post is old but I've heard this a few times and experienced it twice myself.

    Once the battery went dead and had to have the jeep jumped, it triggered the alarm which kept the car from running after a couple of seconds. I had to reset the alarm. Since I don't have a door lock remote, I simply used the key in the door, turned it like I was locking and unlocking which reset the alarm.

    On mine, which is a bit old and beat up (3rd, 4th 10th? owner), if I don't use the key to lock the doors, the alarm will go off 5-10 minutes after I leave the car. Still can't figure that one out but maybe this will help. Good luck.
  • im about to buy a 1994 jeep grand cherokee from an original owner and is in great condition for 1.600 was all fired up about it then saw the reliability marks when it came to transmission and driveline issues and elrctrical, and even the 4 wheel drive! however the classic didnt have those low marks in any category. ive owned several xj's in the past, great wheelers and reliable daily driver, however i was looking forward to the much cleaner and more luxury insides of the grand cherokee, it has the same engine as the xj, the 4.oliter. can anyone tell me something good about the zj, or am i making a mistake choosing thezj over thexj, could use some opinions on this matter
  • My 2005 Jeep Grand Cherokee,had these problems .
    On startup no gages,no warning lights,no read out from the status control pannel, and no turn signals.
    Removed negative battery terminal connector for an hour then reconnected it to the battery.
    This seems to have corrected the problem.

  • I purchased a new 2011 GCL V6 a couple of months ago. All's going well EXCEPT I've had three battery failures so far the last being Xmas Day. Car not driven for three days and battery dead flat. Roadside assist got it going. Now have no radio or other panel features. Screen blank. Never in my 40+ years of owning cars have I experienced this. My other car is a Mercedes C Class 200K and all we do is put fuel in it. It is a perfect vehicle.

    Last trip to the dealer found no fault. Second failure they changed the battery and now three weeks later back to square ne.

    Any thoughts?
  • One of two things is causing the problem. The battery is getting discharged due to a short, or the battery is not being charged when the GCL is running.
    Because the radio and panel features stopped working. the best guess would be the wiring to the automatic switch assembly(or the assembly itself) that allows the radio to stay on when the switch is turned off until the door is opened.
  • So far I have seen Power control module issues, ignition key issues, and pretty much electrical in general as far as i can read, My 2006 Jeep Laredo has now stop working as a result of flickering lights and the car not being able to come on? IS there any way to find out if we can get these electrical issues to be recalled? Anybody else having problems with their 2006 Jeep Laredo????? PLease reply, maybe we can all start a petition and turn it in to the NHTSA!!!! :mad:
  • At first everything in dash went to zero gas showed none speed went to zero. Now it will start but than die. Everything else works but just won't stay started please help
  • Same thing is happening to my '06 Laredo
    We need to start calling this number from Dept. Of Transportation
    NHTSA to make this issue become a recall, 1888-327-4236
    Spread the word! We don't have to pay out of pockets if it becomes recalled !!!
  • If it's the factory installed alarm, you can just not arm it instead of pulling the fuses. With the doors closed use the automatic door locks to secure all doors & liftgate. Then exit the driver door and either slide the lock manually and close the door or close the door and lock it with the key (not the fob.)

    If the alarm works all day at work with no problem, I would consider that someone is screwing with you. Maybe they don't like where you park or something.

    Alternatively, maybe your battery is running down after X hours and your alarm is responding to the drop in current.
  • thank you for this info it help me a lot for time and cost thank you again
  • I had just purchased a 1997 Grand for my daughter. There is a Tech Bulletin out you need to replace the ATC control module. The serial number on the replacment part must be 0109293 or higher. Call dealer ask for TSB# 24-07-97. Hope this helps

    I just had my 1996 jeep for a little over a month and already having electrical problems. My dash board doesn't work and the radio don't play. If it is the brain in the jeep how do i find that out. The fuse blew and if you try to put another one in as soon as you touch it the fuse blow again. every thing else works fine.
  • I have a 1996 Jeep Grand Cherokee. The car stalls on me while driving and the back window goes down intermittently. The battery is new and I have replaced some electrical wiring. I have read that it could be my crankshaft position sensor or my computer box.

    Any help would be appreciated.
  • I have a 1996 Jeep Grand Cherokee. Lately, there have been some intermittent problems. At first, it would occasionally not start due to a dead battery, but with a quick jump, I was back on the road, but wasn't sure what was drawing off the battery. This I had to do about 4-5 times. Then, it happened and I had full power, but had to keep my foot on the gas in order to keep it from dying. Last week, while driving, everything cut out, the radio, the lights, the dash, everything but just for a second, then it all came right back. This happened a couple times. For the past week, I haven't had any issues at all, until this morning. I started the Jeep and it started fine. I pulled out of driveway, put it in drive, but had to stop to let someone walk by. At this point it just died. I tried to restart it, but had no luck. I turn the key and it sounded like it wanted to start, but didn't- there were no dashboard lights when I turned the ignition, no lights, radio, etc nothing. I got it to start once more and was able to get it in to a parking lot before it all cut out again. At this point, the steering wheel won't lock, nothing is getting power, not even my locks, although it stills sounds like it wants to start. Please help!!
  • I had kind of the same problem with my 94 GCL. The first thing I would look at is if the check engine light is coming on when you first turn the power on. Don't turn it clear to turning over, just powered up. If the check engine light doesn't come on and it won't start it is more than likely you computer. Sometimes my light wouldn't come on and it wouldn't start. I would wait a while with the key on and the check engine light would eventually come on and it would start right up. The time waiting for the light to come on was longer and longer until it just didn't come on and wouldn't start. There were also many other things going crazy like yours is but I figured out the check engine light was the main giveaway for it being the PCM. I bought one from ebay about 2 years ago and haven't had any problem since. Hope this helps and good luck.
