Could be something as simple as a faulty sensor. Check through this forum & C-Net forums to find similar symptoms. And...if you take the vehicle to a mechanic, attempt to find one that has much experience working on Jeeps (and I'm not talking about a mechanic at a dealership".
I am hoping that you all can help me out with this issue. This morning I went to start my 1998 Jeep Grand Cherokee. It stalled at first (which it does sometimes). Then I heard what sounded like a thump. When I tried to start it again, nothing. No power to the instrument panel, radio, not even the dinging sound when the key is put in. There is no power to windows, doors or seat either. When I tried it again, the key ding sound came back for a minute and there was a noise coming from the CD player.
I have been having intermittent issues with my Jeep Grand Cherokee for the last year or so:
Moonroof will not open
Passenger side windows and doors would work intermittenly ( I found that unlocking and locking the doors multiple times got them to work eventually)
The driver side door would only lock manually.
A/C worked intermittenly (and would only blow warm air)
Please any suggestions or ideas are greatly appreciated!
Hello again. I am here with good news (but with an "asterisk" *).
As of this week I can report that , so far,
my electrical problem
" Re: 2006 GCL Typical Electrical Issues - Electrical Problem with Dash Cluster" has been solved (*).
After many components being replaced and, with 20/20 hindsight, we now know that some of them were probably OK, but it was difficult to know at that time.
* Front Control Module
* Steering Control Module
* Shift Control Module
* Ignition Power Module
* Ignition Switch (2x)
* Fuse Block
The last effort by the "team" looking into this problem was the big one:
the wiring harness.
The team included:
Dodge/Chrysler/Jeep dealer (local) --- Service Director
Dodge/Chrysler/Jeep dealer (local) --- Senior Electrical Technician
Dodge/Chrysler/Jeep dealer (local) --- Service Adviser
Chrysler / Jeep (Detroit corporate) --- Customer Service Representative
Chrysler / Jeep (Detroit corporate) --- 5 star Engineering Support
and lastly... --- myself
After all the above components being replaced and the same initial electrical problem still there, it was obvious (to me anyway) that we never found the source of the original problem. All the previous repair efforts have to be credited to a best educated guess. So, the last attempt at repair was to replace two (2) wiring harnesses: one forward of the firewall and the other in the cabin.
NOTE: it took considerable effort to persuade the Jeep Corporation to replace these components. Many phone calls were made and a lot of coordination and frankly many hours of normal business day working hours were needed to accomplish this. Many thanks to my company for being so tolerant of this saga as we called it. Some things just can’t be accomplished nights and weekends.
So the two harnesses were replaced and now after a few days, (queue the heavenly chorus) and so far, no problems are occurring. Though, the final verdict is not in yet, it seems to be fixed. I told the dealership service department, that I will be closely monitoring this and it is not over till, quite frankly, many months of good performance.
Bottom line today: FIXED BUT NOT CASE CLOSED
An observation just after repair is that I think my Jeep GC is running better and smoother than when I purchased it from the Jeep dealer (used with 29k). I am now over 80k and the last few days I feel that the Jeep is running so much better and that I am now thinking that this electrical problem was there from date of purchase and just took a little time to reveal itself. If the problem was there at the beginning it makes me wonder whether the original owner noticed the irregularities and just maybe wanted to trade it in. Mechanical problems are one thing but electrical problems are and can be a nightmare.
If anyone out there is having similar electrical problems and it is pointing at "this module" or "that module", and they are replaced and the problem still occurs... then go straight to the wiring harness, albeit not an inexpensive way, but it may just solve the problem(s).

Then slowly but surely additional electrical situations crept up. About a year ago I had to go to town for a meeting, shut off my Jeep all was normal went inside, when I came out Jeep was totally dead it seems that the radiator fan came on and stayed on killing my relatively new battery. I was towed and advised that a module had activated, locked on & died.
A bit after that I experienced very erratic behavior from my fuel gauge. While driving it would go from full to empty and other destinations in between. This lasted for about a week and then my gas needle never rose from empty again. My mechanic said my fuel pump in the tank was failing I would hear a loud noise and the old Jeep would die!
Still running having to make sure to fill tank to full and use trip meter for about 330 or so miles till next fill up, and remembering to reset the trip meter. Glad I live in the sticks always keep extra gas in the back, more danger for a rear end collision!
I am hoping for the fuel tank/fuel pump recall to at least resolve that issue, then I will have to shell out for the module repair and hope for the best!
Funny, in spite of all the crap I do still love my Jeep! :-()
Realize that disconnecting the battery essentially "re-boots" the electrical system, so the gauges will initially look fine. If the issue doesn't re-occur in a period of 7 to 10 days, then you've solved your problem.
One final thing. Never, EVER take a Jeep to a Jeep dealer for repairs such as this. You'll end up paying hundreds, if not thousands without the problem being solved. Think that they will return your money if their work doesn't solve the problem? We both know the answer to that.
1) The radio display is on but there is no sound coming from any speaker. It has the optional Infinity Gold system with the Amp under the back seat. The stereo had worked intermittently for about two years until about six months ago. It hasn't made a sound since then...
2) Trip Computer in Overhead Console- The display doesn't come on when the car is started. Usually it will 'wake up' anywhere from 5-15 minutes after starting/driving it. A few times it hasn't come on at all, even after an hour or more. When it does come on, it works fine as it always has.
3) The Vehicle Info Center (behind the shifter, under the HVAC controls) it shows the vehicle graphic and alerts for Door Ajar, Lamp Failure, Fluids Low, etc. Lately, it just flashes with the time (which shows at 12:00 all the time). It worked fine until the last couple of months....
Any ideas on my electronic gremlins? Could it be as simple as a fuse or two? Or maybe a big fuse in the Power Distribution Center (under the hood)?
Any ideas or suggestions would be greatly appreciated! I'm trying to get it ready to sell and I want to fix these problems first if I can.
THANKS!
I hadn't ever heard BCU before, but I did a search and it seems there is a "Body Control Module"...perhaps someone can enlighten both of us on what that is!?
I have a problem where in the morning, "sometimes", I turn the key and it doesn't start..no noise..if I keep holding the key it might start.. if I release the key, don't want to break it...and try again..it often starts up. It eventually starts and I find it strange that I hold the key for a while and it starts.. like 20 secs.. This is random, not all the time but when the engine is warm, I haven't noticed this problem.
Well a few weeks ago, I had the power to the engine shut off, then turn on in about 20 seconds with power returning I could drive without to much problem. Well yesterday, I had this same problem happen three times. The first time, I pulled in a gas station and shut the car off and turned it back on. The second time, I was on the free way and the car slowed down but in about 20 secs, power came back and I got out of there.. then about 5 miles later, I lost power again and pulled off the express way, it never returned, so I stopped shut off the car, turned on the key and it started again and I drove home.
Anyone had this type of problem? Like to hear your solution, write me at jtflex02 at yahoo too ...

I got a notification to look at my gauges and I also noticed the sentry key light light, everything else looked normal.

Some times finding a problem with the Bus System is very time consuming. It could be an internal problem in one of the computers or it could be a wiring problem.
If you have your receipts from when you first started having this problem and it was never fixed correctly Chrysler may honor the warranty. Also the dealer will have copies of any warranty work that was done to your car.
If you don't get satisfaction from the dealer, you might try chrysler customer service.

It's too bad because the new 2011 JGC looks awesome but I would now be wary of buying another JCG. Thanks, Joe D
The symptoms you state are very similar to what i went through with my 2006 GCJ-L. After the dealer replaced many components on BUS Can-C it then came down to the wiring harness. alot of modules that were replaced prior to finally replacing the wiring harness were probably Ok but it was not easy to know at that time.
From all the threads I have seen on this site and others i would venture to tell you... ITS THE HARNESS But I reserve the right to be completely wrong,
Since my harness has been replaced, at 85k miles I believe my Jeep is running better than when I bought it used from dealer at 29k miles..
it is my suspicion, now with 20/20 hindsight that the original owner may have experienced the same problem I had (sporadic dash cluster / gauges, etc), and said ... electrical problems - time to trade it in...
These electrical modules at $400+ and 500+ a pop are an expensive way to go the route of " let's try this and see if it works"
see my earlier posts for more info
best regards
please keep us posted on your progress

any imformation would be greatly appreciated thanks
I have 1995 GC linited w/ V8. Same no start condition right now. No power to fuel pump. Trying to trace power from pump backwards to Bat. Will keep you posted. Where did you find melted wires? What engin? V8 or I6?
I have a 2005 Jeep Grand Cherokee and it has been having what I think are electrical issues. About a year ago the lights would flicker on the dash and radio/clock intermittently. It wasn't a big issue, just annoying. Nothing else was affected...gauges and everything worked fine. It has been doing this on and off for a year, but today driving into work it started up again but the emergency brake light flickered too. Then it happened again but stayed on for a few seconds...and so did the ALB warning light. When this happened all of the dash lights turned off and I heard a pop in the radio speakers and the radio went off. Then it all went back to normal! This happened 2 more times on my 20 minute commute. I don't know if this is a dealer issue or if it's something I may be able to handle on my own (like if it's with the battery or something). The battery has been replaced recently but I have always had an issue with corrosion on one of the connectors. Could this be it? Just a bad connection? I'm just worried this may be effecting my outside lights, but really there isn't any way to tell since it happens so infrequently.
Any advice is greatly appreciated.
Thank you!
It's a crying shame that the 2nd gen (99-04) had so many problems, because they are still some of the best looking SUVs ever made, IMHO. I'd love to have an '04-'05 Overland with the HO 4.7L V8...but I know it would be a money pit, to say the least.
I have a friend who drives a 2008 Limited 4x4 that she bought new for over $42k! In the first two years and 42k miles, it had the transmission replaced, multiple components of the Quadra-Drive system replaced, an oil leak that took several service visits to finally fix, leaky radiator replaced, a fuel pump and several more minor issues. It also has a few intermittent electrical gremlins, including interior lights that fail to work at all sometimes and refuse to go off at other times! And the rear tailgate warning light comes on all the time, even when it is securely closed.
I started with working with her last year, so I didn't know her when she bought it. Otherwise, I would have tried to steer her in another direction! Or at least filed for Lemon Law protection, but it was too late by the time I met her.
The 2011 looks amazing and they keep talking about it being the highest quality vehicle they've ever built. That may be true, but for those of us who have seen what they've been building for the last few decades, why give them another chance and take the risk???
warning lights are lit up. Were you able to find out what it is and did you haveit fixed
Thanks Brian
