#563 of 707 1996 Jeep Grand Cherokee doing all kinds of wierd electrical stuff.
Nov 01, 2011 (2:38 am)
My 1996 Jeep Grand Cherokee was running fine, then one morning while taking my kiddos to school the speedometer started going crazy, bouncing all over the place. A few minutes into this the rest of the gauges started to do the same thing and it started to idle really weird like I was running out of gas, but there was still half a tank left. I did notice that the volts were reading half of what they usually do. I tested the alternator and battery, both are fine. My local dealer hasn't a clue what it could be. Can anyone please help me as to what this could be? The snow is coming soon and I have been without a vehicle for 2 months. Any suggestions would be great. Thanks for your time and Jeep wisdom!
#564 of 707 Turn signal issues.
Nov 01, 2011 (9:47 am)
A strange problem poped up with my 2001 Grand Cherokee. About 3 weeks ago the left turn signal stopped working. I thought that I would check the bulbs that weekend, but I forgot about it and a few days later I noticed that it was working. Now it will stop working and the next time I drive it, or later on the same trip but sooner or later it will start working. I can not pinpoint anything that I can think may be causing this. Has anyone else seen anything like this?????? Thanks for you help. Jerry.

I know you posted this a long time ago but I just wanted to let you know how much it's helped me... I had the EXACT same problem. I was happy to read how simple it was to reset the system. Just unplug the ground, wait a minute, then reconnect. Everything's fine now.
Now all that's left to do is change the heater core, Blend doors and Hydraulic radiator fans' solenoid and my 2002 G.C. will be like new :~1 Guess that's why Jeeps acronym is Just Empty Every Pocket.

I have a 1996 Jeep Grand Cherokee and would do a slipping thing, the gauge would go up and it was like a stand still, then it would reengage itself. I thought I was out of gas like 3 times and had it towed the last time, cuz it was just chugging and wouldn't drive. It was a simple wire on the Throttle Position Sensor, the wires were exposed/split open. You could either need the wire replace or the TPS replaced or both. Jeep has been running fine now. TPS is the brains to telling your vehicle how much airflow, and fuel delivery to your computer of your vehicle.When its defective, it causes intermittant burst of fuel from the injectors and an unstable idle because the PCM thinks the throttle is moving. So it is a very important part. Its located right under the throttle body at the end of the shaft right on top of your engine. It can affect your gas mileage and how your vehicle runs. The wire is like $5 and if you do need to replace the TPS its about $35, plus labor. Shouldn't take longer than 20-30 minutes to do. Good luck!
#568 of 707 2005 Jeep Grand Cherokee Module Problems
Nov 04, 2011 (5:13 pm)
Hello I hope this post may help some people if they are having the same problem with their Jeep. A family member owns a 2005 Jeep Grand Cherokee 3.7 V6. The Jeep was bought brand new and she never had any major issues with it. The vehicle was well taken care of and it only has 73,000 miles on it.
On May 9, 2011 there was a problem with the dashboard and tail lights going out. You would be driving and all of a sudden everything on the dashboard would go dead, rear tail lights would go out, but the vehicle would still run fine. She shut the vehicle off, went to restart it and everything would come back on as if nothing happened. It was brought up to the dealership and had to be left there for two weeks.
No error codes were found on the computer, and the instrument cluster was replaced which seemed to fix the problem. The Jeep had two incidents where the dash went out again and it was brought back up and checked. There was a loose connection in the wiring which was fixed and the vehicle was fine. The total cost for the repair was $943.22. I could not believe the cost and this is why I hate new cars with extra electronic devices that I feel are not needed. It is so much cheaper to fix my 1975 CJ5 which runs great, lol.
Back to the 2005 Jeep Grand Cherokee, in the month of Aug the check engine light would come on and off. Which happened a few random times but the vehicle ran fine and everything worked or so we thought.
The last week of Oct my family member went out to do some shopping and all of a sudden on the dashboard all the brackets on the gears were on as if the vehicle had all gears engaged but the vehicle was in drive. Also the check engine light was on too. When it happened the vehicle went into a low gear and was dragging. She pulled over shut the Jeep off and turned it back on. Everything came back on and seemed to be okay and she made it home. We turned the Jeep back on once again all the brackets on the dashboard were on the gears even though the vehicle was in park and the check engine light was also on. I noticed the brackets were flashing on and off. So we called a friend who repairs older Jeeps and asked if we could bring it up. I drove the Jeep everything was fine. I stopped at a red light when the brackets came on and the vehicle went into a low gear. I pulled over and tried to restart it until it would go off. I got lucky and made it up to his private shop. These are the codes that came up on his computer.
#1 P0700 Trans Control Sys Malfunction
#2 0404 Invalid Data Recovered From Control Module Gear Shift
Note: P0700 Came up twice
He said you have to take it up where they have the computer to put it on. Also sometimes the codes are not saved on the system in your vehicle or it might take several times for the computer to save it. So I made my way home and we had the vehicled towed to the dealership. I t was unsafe to drive and we did not want to ruin the 4x4 or transmission.
On Nov 2, 2011 the vichle went up for repair and on Nov 4, 2011 it was fixed. They replaced the PRNDL/ESM Module and so far today the vehicle has been okay. The repair cost $1,199.66. I really hope that the Jeep is fixed and we do not have any more issues. The computers and repairs are so expensive and can be a nightmare. I dislike having a computer decide if my 4x4 should be on or not. That should be up to the driver to engage because what do you do if the computer malfunctions and you can't shut it off? I hope this helps and if anyone has had the same problem please let me know.
#569 of 707 Can't start my Jeep 2007 Disel

I went to my Jeep Cherokee today and it won't start.
Jeep acted strange this week. Alarm went on three times this week without any reason.I got message on dash board that tailgate are open but they not.
And finally before I turn key my wipers went on on perfect weather.
Now when I turn the key I got all light on the dashboard and after 5-7 second everything disappear and looks like there is now power. Of coarse engine not starting. I can only hear some noises going i think from transmission.
Anybody have any idea. please help
#570 of 707 No illumination
Nov 07, 2011 (6:57 pm)
Hello, I have a 2005 JGC and the vent, temperature and directional knobs all do not illuminate now. Makes it hard to see during night driving. Could this be a fuse? If so, where would it be located? Thanks, Joe

95 jeep cherokee 6cyl. 4.oL Turns over but no fire. Have replaced crankshaft sensor, ignition coil, coil wire, plug wires and plugs and rotor. Rotor is turning when engine turns over. I cant figure it out! I do hear a clicking coming from one of the relays, but I swapped relays and both work meaning I tried the relay in another spot. Fuses are all good and fuel pump has been changed. Any idea on what next? Am I down to replacing the distributor or is there something else to check? And have a happy turkeyday everyone.
