someone please help! by bovee

I have a 04 JGCL, it has been in the shop 3 days now and is racking up labor cost. It seems to shut off whenever I hit any bumps in the road, at high speeds, only the speedometer and fuel gauge seem to be effected, they zero out and then come back. At slow speeds, when I hit a bump, it stalls. Mechanic says it is a short (no kidding!) but he can't locate it. Has anyone else experienced the same problems?

That doesn't sound like a short. It sounds like a broken circuit or bad switch. Have they checked all the electrical connections?

not sure what they have or have not checked, I got frustrated with the mechanic and picked up the truck today, now it won't start at all and the fuel gauge is reading empty, the low fuel chime keeps dinging, and when I drove it home, it had 3/4 tank. What kind of circuit or switch should I be looking for, and could this be a bad fuel pump or sending unit? thanks for your help.

The speedometer and gauges are all electronic and there are a number of electrical connections between the battery and these components. The problem could be at any of those junctures. I don't have hands on experience and don't know how accessible any of those would be so we'll have to wait for someone knowledgable to jump in here - anyone?
 
I am a little surprised the mechanic didn't pick up on any of this (electrical, fuel pump, sending unit, etc.) if starting it is such a problem. Perhaps a new mechanic would be helpful?

odd problems by barnabyjones

I have a '97 JC/XJ that I bought used. Ive had it since early '01, all power options. Its always had electrical problems. Im thinking it might have something to do with the remote start the previous owner installed...
 
 First off, sometimes, most times actually, when I roll down the rear window on the driver side, the locks trigger. And then I cannot lock the car without doing so manually for a undetermined amount of time. Also, sometimes the car simply will not start, after I drive it for any length of time. Put the key in and the dash comes alive, but the engine wont turn over. I have to wait anywhere between 5-15 minutes typically for the engine to start. Doesn't matter if I take the key out or anything. Seems like the computer needs to reset?
 
 Ive asked various mechanics and they all have no idea. Ive never had the money to hunt down the problem...

2004 Problems(electrical) by sage3339

Bought a 2004 JGCL last August. Figured I would get something newer so my vehicle wouldn't nickel and dime me to death. Sadly mistaken.
 
3 weeks ago I had to have the Throttle Position Sensor replaced, after doing some research this seems to be a common problem. (rough idle, rpm fluctuations in cruise control, high idle at startup regardless of engine temp.)
 
I had some electrical problems. My radio quit working intermittently. I had to mess with rear driver side window button to get power to the radio. Last night driver side windows would not work. This morning none of the windows will work, instrument panel light cluster is lit up like a Christmas tree, fuel gauge, speedometer, tach does not work.
 
I think that it is a problem that has to do with a short and moisture in door panel. This issue happens mostly after rain or if there is a melt from the winter. Does anyone know if there were any recalls? This seems to be a common problem.

I got a 94 Jeep grand Cherokee Laredo 4.0 6cyl. automatic. not a 4x4.. it just started to sputter recently; then die. i'm able to turn it over again and it will be fine for a day or so. I checked the fuel pump by disconnecting the the lines from the inline filter. turned it on the on position yes pump was fine .however i did change the filter it was there and disconnected and only 12 bucks ....why not. Worked for another day and a half. started the same thing...... was acting like it was running out of gas bucking and what not. i popped the hood then i got a better idea of the prob. ...the engine stalled then i started to hear shocking like something was arching somewhere. i ran around to turn off the car and my tachometer was jumping like crazy from 0 - 6,000 rpm + up and down in variation. i cleaned my posts and dis cap. it seemed to be fine for about 8 miles and started again. please do you know what this is? i'm up for options and ready to get dirty. please help?

Voltage Leak...TITANIC AHOY by frumunda

Ok. I went out and bought a used 85 JGC with a 95 4.0L transplanted into it for 700.00 bucks, solid as a rock, no leaks, runs, drips, or errors. Simple, eh? Nope. Apparently the previous owner was committed to a local "sanity re-establishment facility" due to the Jeeps proclivity to eat batteries. As far as I've been told he managed to ascertain that there was some sort of voltage leak but could not narrow it down to which system the gremlin had taken refuge. At that point, he ripped out most of his cranial skin with his hair and subsequently had to be sedated and rushed to a doctor. Witnesses were heard to say that there were muted cries of "Only in a Jeep? ONLY IN A JEEP?" emanating from the back of the ambulance. So I put it to you, dear readers; where do I start looking?

AH HA! Part DEUX......So I was looking around under the dash, and I noticed a few things...First, the dome/overhead console fuse was blown. Second, the rear wiper fuse was on vacation. Third, the ignition circuit tag under the dash on the fuse block itself has some sort ot cobbled up wire running from it to some unknown point within the dash.
And now for something COMPLETELY different...so the power lead to the main fuse/relay assembly underhood seems to be the area of suspicion. I did the ye old "remove a lead" method to see if I could elicit a spark, and VIOLA'! a flash of energy. So its somewhere within there.
 
The search continues...

Lights on nobody home by anthnycarr

I'm having a problem with the window and door lock controls on the driver's door of my 04 Grand Cherokee. My remote unlocks all of my doors except for the drivers door and none of the windows will roll down. The doors do not lock when I hit 15 mph and the interior lights stay on the entire time the vehicle is on. They eventually dim out when I turn the vehicle off and lock it, but it's taking a lot longer for them to turn off than usual. I've checked the fuses inside and under the hood and all looks well. everything else in the vehicle seems to be working fine. Any ideas?
