#605 of 708 '96 Grand Cherokee- NO electrical power at all by kpelley

Jan 08, 2012 (10:19 am)

I have a 1996 Jeep Grand Cherokee. Lately, there have been some intermittent problems. At first, it would occasionally not start due to a dead battery, but with a quick jump, I was back on the road, but wasn't sure what was drawing off the battery. This I had to do about 4-5 times. Then, it happened and I had full power, but had to keep my foot on the gas in order to keep it from dying. Last week, while driving, everything cut out, the radio, the lights, the dash, everything but just for a second, then it all came right back. This happened a couple times. For the past week, I haven't had any issues at all, until this morning. I started the Jeep and it started fine. I pulled out of driveway, put it in drive, but had to stop to let someone walk by. At this point it just died. I tried to restart it, but had no luck. I turn the key and it sounded like it wanted to start, but didn't- there were no dashboard lights when I turned the ignition, no lights, radio, etc nothing. I got it to start once more and was able to get it in to a parking lot before it all cut out again. At this point, the steering wheel won't lock, nothing is getting power, not even my locks, although it stills sounds like it wants to start. Please help!!

I had kind of the same problem with my 94 GCL. The first thing I would look at is if the check engine light is coming on when you first turn the power on. Don't turn it clear to turning over, just powered up. If the check engine light doesn't come on and it won't start it is more than likely you computer. Sometimes my light wouldn't come on and it wouldn't start. I would wait a while with the key on and the check engine light would eventually come on and it would start right up. The time waiting for the light to come on was longer and longer until it just didn't come on and wouldn't start. There were also many other things going crazy like yours is but I figured out the check engine light was the main giveaway for it being the PCM. I bought one from ebay about 2 years ago and haven't had any problem since. Hope this helps and good luck.

At this point, absolutely nothing comes on when I turn the key- not part way or all the way. I am having it towed now. Will I be able to pull a code off it still if its the actual computer I have to replace? Are there any other tell tale signs that I should be looking for as well?

#609 of 708 95 Jeep GCL Alarm problems by bigbadwolf1

I have a 95 JGCL 5.2 liter with factory alarm. I've had this truck for over 12 yrs, and I've had this problem for probably 5 to 8 yrs.
with the doors are unlocked, if I open a door the dash lights and the 4-ways start flashing, I have to hit the power unlock switch to turn off the flashing lights or it wont start, If the doors are locked, I have to unlock the passenger side door or the alrm will go off, even when I unlock the passenger side door, the lights still flash and I still have to hit the unlock button.
 
I have cut the violet wire with the yellow stripe, that comes in from the fire wall on the drivers side floor board, and grounded it, that was supose to have disabled the alarm, that didnt work, and I have even removed the security alarm module.
 
the alarm doesnt come on now when I unlock the drivers side door, but the light still flash when I open any door, and if I dont hit the unlock button to turn em off, it will drain my battery.
 
does anyone have a clue as to how to fix this??????

Car is 5 months old, less than 10K miles: Replaced radio/navigator three times and it still stops working intermittently. Dealer said no one else has problem, suggested another replacement.
 
Now alarm goes off intermittently, once while car was running and I was parked, another time when no one was even near the car and I was in a building. Don't dare lock it. Dealer says can't see a problem.

Can you expand on this problem? I have a 2006 Dodge Ram 1500 with the 5.7L V8 and the 45RFE transmission - 3 days ago, my heater vents went a little off (the floor vents stopped working) and the day after that, my CEL came on, and I have no automatic shifting - cant manually shift into 1st at all, and can only manually select 2nd, or D (which I'm guessing is limiting me to 3rd gear only). I'm about to drop $327 on a transmission control module, and would like to avoid that if it could all just be from a vacuum leak. would you mind linking us to some of the stuff you've read online about this? (Haven't tried cruise control, but I wont be driving this vehicle until it's going in for repairs)
 
Thanks!!

I had my alarm going of randomly in my '95 Grand Cherokee. The fix was easy. Remove the drivers door panel, in the lower left part you will find a connection that runs up to the door key lock. Unplug this and put a jumper in the end that comes from the front of the door. Tape this up well and leave it unplugged. The jumper grounds out the factory alarm and you will never have alarm issues again.
