#266 of 735 1998 Grand Cherokee 4x2 electric problem
Feb 12, 2010 (5:35 pm)
I Have a 1998 Grand Cherokee 4x2. A few months ago my gauge cluster began to turn on and off, and eventually while driving the Jeep just shut down. It still had electic power but would not turn over. I ended up having to replace the computer. Now about two months with the new computer the gauges are turning on and off again. What should I check for, or replace before the computer dies on me again.

I have a 1999 Jeep Grand Cherokee Laredo 2x2. A couple of weeks ago my vehicle started giving me problems. Wehn i would crank my Jeep up the oil gauge had a reading of zero even though i had my oil changed two weeks prior to the incidents. When ever i crank my Jeep up and press my gas pedals the oil gauge goes back to the middle, but as soon as i drive off it falls back down to the zero and the check guage light comes back on. Does anyone have an ideao to what it could be? Thanks

Your problem may fall into the same category as the rest of us, as this may ultimately be another one of those electrical problems that many of us don't have a resolution for.
However, the first thing to do, is to check the diagnostic code for your problem. It's an easy thing to do on the JGC (at least on my 2000 JGC it is). With the vehicle not running, turn the key toward ACC (backward or opposite of starting) once, then back to the original position. Perform this three times. On the third attempt, the "P" diagnostic code will be displayed in the same area as your odometer, followed by the word "done". Perform an internet search for Jeep diagnostic codes, to find the reason for your problem.
Realize that this may be a false code; i.e. something that doesn't really indicate the true problem. As I said, many of the older Jeeps are experiencing problems with gauges not working, in conjunction with dashboard lights being lit up. No one appears to have a resolution for this. If you take the vehicle to a dealership, they'll probably attempt to change the PCM and/or BCM, which will cost you a pretty penny. Rest assured, that won't solve the problem.
Check other online boards like CNET, but you won't find much in the way of help. Sorry.

Can anyone help me with this New Problum,
I own a 2001 Jeep Grand Cherokee 4.7, i drove it yesterday and it was running great, now today it will not turn over,when you open the hood you smell a strong electrics burning under the battery? Does anybody know why i am getting a strong smell of electrics burning and would this stop the truck from turning over.
Also i replaced the battery last week.

It sounds like you either have a short circuit somewhere in your electrical system or your alternator is burned out.

OK, so these problems may not have anything to do with one another but i get the sense they are related...
Jeep GC 2001
- wipers stopped working about a month ago. then a few days later started working again
- tailgate power lock stopped working a week or two ago. works sometimes but mostly not
- today, blinkers would not work. Lever on steering column goes up and down, but no "clicking" or arrows showing on dash.
Anyone have any thoughts?
and somewhat related, How do you check or change the fuses in the box under the hood?
thanks- E Kamer
#274 of 735 1995 Jeep Cherokee Wont Start
Mar 28, 2010 (1:09 pm)
I just bought a 95 JGC with straight 6, auto 4WD, 159,000 miles. The tranny is supposed to be out. When I looked at it we had trouble getting it started, but after leaving the key on for several minutes I heard a click then the fuel pump ran and I was able to start it. I towed it home today and now it wont start. Im not getting power at the fuel pump. Ive checked ALL fuses and relays and all are good. Im leaning towarda PCM problem but dont know how to check it. I also need a wiring diagram that shows what wire coming from the PCM powers the fuel system. There are some otehr issues that Ill be asking about but need to get it running first.

Update: Its a 1994 JGC. I replaced the pcm with one I found in a salvage yard and it now starts. The tranny is messed up. Bucks and shakes sometimes when in drive with foot on brake. reverse seems fine. Not much power driving forward. Power windows are not owrking. I replaced the master switch with one from salvage but they still dont work. There is power at the master switch. the latch on the rear hatch doesnt work eight, seems like the handls qont pull the rod far enough to release the latch. same on the rear passenger door. Also the power door locks dont work on all of the doors.
