#192 of 708 2002 Jeep Grand Cherokee Laredo fuse problem by revell

Oct 09, 2009 (4:44 pm)

Hi folks, I have a seriously strange problem. Two days ago my turn signals, and air controls on the dash went out (blown fuse 10amp). Replaced the fuse and all is good, so I thought. The moment I placed the gear selector into Reverse the fuse blows again. The fuse blows if I go from Park to Reverse, or Neutral to Reverse.
It works fine in Drive,2nd,1st, and Park.
So now I have no Reverse lights due to the fuse being blown. I have tried disconnecting the reverse light switch from the transmission, no luck... Also I have removed the reverse light bulbs, no luck... I have checked other bulbs for corrosion,etc. no luck....
Why would my Reverse gear be taking out my turn signals and air controls?
Can anyone tell me what might be the problem here??
I have never had any electrical problems before,until now. And I have never heard of anything like this.

Problem solved
 
The culprit was the neutral position sensor harness. It seems that over time the harness had rubbed against and bracket mount for the transmission and exposed bare wire for the Reverse causing a ground short.
  
Here is how I trouble shoot it. I started the vehicle and then unplugged the neutral position sensor and the placed the vehicle into reverse and it did not blow the fuse.
So I then started checking the harness for problems back to the fuse box. Luckly I didn't have to look far. I had bought a Hanes Manual to get the wire diagram so that I would know where/what was all tied into the reverse electrical system.
After three days of brain racking, all is good now.
 
NOTE: The vehicle will not start with the sensor unplugged, so be sure to start the vehicle first.

About a year ago, I was driving home from a concert when everything went haywire. Head lights would dim in and out, the gauges went crazy, odometer flashed on and off, cd player shut off... And then my Jeep would start to stall out and then turn back on while I was driving. So I replaced the battery and everything was fine until about a week ago this problem started up again.
 
Sometimes I'll go out and it will start right up, other times it won't even click when I use my power locks. When it doesn't start I have to sit there and continue turning the key on and off until it eventuallyyy starts up. Usually it won't make a sound when turning the key. The battery is only a year old, I have a warranty on it but Autozone checked it and said the battery and alt are fine.

#196 of 708 bad connection by frnchhrn

So I just found out today that the wire going from the solonoid to the starter is bad and needs to be changed. We have a 2006 Jeep Grand Cherokee, and the mechanics keep telling us that the wire can't be changed. Something along the lines of the entire engine will have to pulled out in order to change it. Is this the case, or does anyone know of another way? I really don't want to have to pay the high cost of labor for a cheap part.

This sounds a bit fishy to me too. Almost any wire can be changed, even if you have to run it through the firewall to the cabin (e.g., that's what audio installers do all the time).

I agree with both of you, I thought it sounded weird too. I guess the issue is that the wire is way down inside, and supposedly the mechanic couldn't get to it even with really long needle nose pliers.

i dont know where the wire would be so hard to get at that you could not rerout the wire (if its that bad would have to remove engine to change the starter)

#201 of 708 car goes 200 yards down the road then stops by eddobbo

Oct 25, 2009 (5:20 am)

i have a grand cherokee 3.1 2000 Turbo Diesel Automatic. right i was driving along the road the other day and everything just completely locked up, braked a couple of times and stopped. engine still running. i could drive it in secound and first, as i had to get it to the side of the road. today i decided to have ago at driving it down the road in "drive" again and it was fine for 200 yards down the road, then it would brake twice and go in to a complete stop (didnt make a noise though). i put it in to 2nd and it went 200 yards down the road and the same kinda happened again, so finally i put it in to 1st and it went quite a distance up the road but it did the same again(same again no noise). reverse works aswell btw. the reason i was tihnkin it was an electrical problem was because the transmission fluid is perfect, it doesnt smell burnt or look black and i thought that if it was something mechanical it just wouldnt drive at all or make a clunking noise. ive done the trick of turning the ignition on and off 4 times and it come up saying "done" meaning there is nothing wrong with the car :S
  
btw ive also had a problem with starting it, i can turn the key to turn the radio on but its takes a couple of goes to turn the engine on as it just make a clunking noise. also aircon hasnt worked and one of the electric seats doesnt work.
