#519 of 708 1998 Jeep Grand Cherokee - electrical problems
Aug 06, 2011 (12:51 pm)
So happy to find this site. I have a 1998 Jeep Grand Cherokee. It started out with my electrical windows not working and then my ac wouldn't blow thru the vents and then yesterday going home my dashboard lit up and everything went haywire, the windows wouldn't work unless I hit the driver's side door with my arm and the windows would work but then the dashboard went crazy, speedometer went to zero, gauges went crazy. It was very scary as I travel on the I-10 and am a little ways from my home. Please help me in any way you can!!

Hi! I just want to say I have a 2005 Jeep Grand Cherokee Laredo that we bought used, are still paying on, and I think its a piece of CRAP!! Since the very beginning we have had electrical problems starting with the radio. You have to hit clock in order to get the radio to work. Then it began going off like a Christmas tree. I will be driving along, I will have shifting problems, dash lights all blinking and going crazy, ac blower turning on and off, headlights and rear lights blinking like crazy (this makes me feel really safe on the highway at night), gauges going crazy up and down and turning off. I WILL NEVER AGAIN PURCHASE A CHRYSLER PRODUCT IN THIS LIFE TIME!!! I do have to ask if every one is complaining of the same issues then why have they not been forced to be accountable and have a recall???

I feel your pain. The first day I drove of the lot my radio stopped playing. No need to tell u my story. Everything u mentioned are the exact same problems I'm having. Light flickering night. I'm surprised someone hasent gotten out of their car to curse me out thinking I'm flashing them. Its falling apart. I have a 06 with 77 thousand miles. And from this start its gone while. The first 6 months of having it. It was in the shop 5 times. BUT!! The dealing camt even tell u what's wrong. So sad. I love my jeep. But never ever will I purchase another one.

Like I have said to many others on this forum. it is the electrical harnesses. Period. The harness defects tend to also burn out control modules.

Sorry for bluntness. On quick break on mobile platform

What is the electrical harness? And is it expensive to fix. I was told I needed a new computer for the car. Is this what ur referring to?

I drive a 2005 JGC (5.7L) with 53,000 miles on it.
Like mech3, the car would randomly feel like it was stalling out when I would step on the gas pedal. This wouldn't happen frequently, but definitely at very inopportune times. The check engine light would come on and if I wasn't stopped, the car would feel like it was starting to shut down.
I have taken it to the shop now three times, and this is the first time they were able to get an error code generated. Note, this is also the first time that the check engine light actually stayed on by the time I arrived at the shop.
Like bhunley, I am having the crank shaft sensor replaced ($420) as well as a couple other sensors ($140). The mechanic said that when the crank shaft sensor isn't receiving the signals correctly, it essentially starts shutting down the car (or something along those lines). He did say that the error needed to happen a few times before the code would get registered by the computer, which is why they couldn't target the problem the first two times I brought the car in. Thankfully, they never charged me for those trips!
Anyway, I'll post back in a few days to let you all know if that fixed my problem. Best of luck to you all...

There are a number of harnesses. There are also generally THREE (3) "BUS" circuits that are tied to various modules. One harness is ahead of the firewall (eng compartment) and other harness(s) behind firewall. it is designed so that certain electrical systems are on specific BUS circuits. I have heard of many with stalling problems and also of wipers or headlights turning on and off on their own.
A technician told me that some of the circuits "fail safe" meaning that when they malfunction, headlights may go on or wipers may runs etc.
My particular problem with my harness was for many times (5) diagnosed as a bad module here or there (refer to my earliest posts in these threads). Some modules were replaced more than once or twice. In my experience, some of the modules were actually OK, but the harness was shorting out modules and ignition switch, etc. I would not be two miles down the road from what was supposed to be a successful repair only to see same "crazy dashboard light show" happen again and again. They did not believe me until i filmed it on my phone's video capability.
Quite frankly, with the new harness my Jeep is running so smooth and true and is like it was always meant to be. It idles smoother than when I bought it, as well as consistently performing well in all kinds of Wx.
The repairs for all the modules replaced totaled $2100 for mine, which I paid over a series of repairs. (Oouch !!!) Then I got in touch with Jeep Customer Support and they were, IMHO, great about dealing with my issue. I was totally documented with dates, times , receipts, etc. I even had them speak directly with Jeep Service Manager as well. In the end they covered to cost of the harness so... I don't know what the actual expense was but BOTTOM LINE.. it was worth all the agro that i went through.
Years ago I personally installed a new wiring harness on my '72 Honda 350CL motorcycle and it to never ran better.
So, as one can see, I am "all about the harness" as being a prime source of many of the symptoms I read in this forum. Sadly, only one way for you to find out...
Best o' Luck
103,000 and running smooth
#528 of 708 2001 grand cherokee Not Starting
Aug 16, 2011 (10:25 am)
I have a 2001 jeep grand cherokee. I am currently having problems getting it started. It will start for 3-5 seconds and stall out. I checked the fuel rail and Im getting plenty amounts of gas. However on rare occasion it starts up, my gauges and sometimes windows and door locks dont work. Although my dash lights do. I checked for a faulty instrument cluster and a bad ground... not the problem. Oh and the security light is on! Any insight please? Thanks
