  • I have a 1994 GC 4x4 4.0L I6. one day i started it and noticed my security light on the dash and my head/tail lights were flashing. The engine killed. then everytime i tried to start it back up it ran for 3 seconds and dies. pulled out the security alaram box to stop bliking so i wouldnt kill the battery. Any suggestions? I was thinking the CPS or my ECU? i might just replace both and see where i end up.
  • Hi all,

    First time poster. My daughters 1997 grand cherokee's battery has been draining and will only hold a charge for about 36-48 hours. We replaced the battery 6 months ago and just had it checked out and it is good.

    It's been awhile since I've got into this sort of stuff but I whipped out my trusty multimeter and did some checking. I disconnected the postive cable, connected my multimeter to the post and cable and sure enough it was reading 188 milliamps of pull. I believe about 30 milliamps is normal for the clock, etc. I then proceeded to pull each fuse one at a time and when I pulled the 50A fuse, it dropped down to near 0.

    According to my fuse box legend, this fuse (position 11 in the fuse box panel) is in line for the memory functions, power window, power door locks,power mirrors, remote keyless entry and the trailer tow package which we do not have.

    My daughter told me that a few months ago the power door lock would not open the passenger side door which had to be opened by the internal latch of with the key from the outside. With this said, I definately see a connection between the battery drain (related to the power locks) and the door not opening when the power door lock switch is hit.

    Any ideas on where to start would be much appreciated.

    go in and unhook the power lock mec on the door and see if lowers the draw on the battery if so power door lock mec on that door
  • Thanks. Is the power lock mec(?) on the door located inside the door panel? Since the passenger side door is not unlocking, would that be the door I should focus on?
  • Sorry first timer
    Any ideas???

    There are some binding posts over in the maintenance and repair board - try a search there for "bind". Here's one example:

  • I am still trying to track down the 3+ amp draw in my daughter's 1996 JGC. So far nobody has come up with the Power Distribution Center diagram that matches the one in her Jeep. The cover is part # 56018905. It does not match the owner's manual, and there is not one in the Haynes that we have for it. If anyone has an idea on where to get this block diagram,. I would appreciate it.
  • Hi,

    Perhaps you are having the same confusion I had. Just a guess. When I went to the owners manual for our 1997 JGC, it shows a fuse box located by the inside passenger "kick box" just below and to the right of the glove box. Nothing there!!!! When you go a couple of pages further in the manual, it shows the "power distribution center" which is the fuse box located right behind the battery toward the firewall. Not sure if that's what you mean. 3+amps is a huge draw!
  • Thanks for the tips. I discovered that the power door locks are not working for both the front passenger and drivers side back seat. I can hear the motor trying to operate the locks but does not open and close the locks. Thanks to your procedure advise I easily removed the dooe panels and disconnected both of the power lock cables. As luck would have it, when I went to check the draw again with my multimeter, it stopped working! Tried new batteries still nothing. Will have to buy a new one.
    Thanks again
  • Hey good people,

    Can anyone tell me where the neutral position sensor harness is? I need to check out an odd reverse light/blower motor malfunction on my son's 04 Grand Cherokee Laredo.

    I appreciate any help.
  • Hi back to you!
    I'm not really confused about the locations. The fuse panel is inside on the passenger side kick panel. The Power Distribution Center is under the hood. I would like to see the block diagram for the PDC. The one in the Manual must be for a different year. The part number on the cover is 56018905. Thanks for the reply, though.

    Yesterday the interior lights wouldn't go off unless they were physically turned off on the column but the "readout for an open door" didn't work for the drivers door so I assumed something was amiss with the door itself. However it did work for all other doors. Eventually the interior lights went off and I checked the fuse when I got home (it wasn't blown). We left later and none of the lights on the driver door worked (the lock and window controls) and neither did any of the controls. Now none of the windows will work. We have looked and neither of the fuse boxes have any fuses labeled for the door locks or power windows. I'm assuming it's a relay around the door or where the door wiring links in but we haven't figured out exactly how it links in. Any ideas on what may be causing this or a way to fix it without a huge garage bill? - which is where I think probably will be heading.
  • I just had the same sort of problem on my 03 Grand Cherokee....No power getting to the drivers door panel.....couldnt open ANY window from ANY door switch....could not lock the drivers door with the remote and the wierdest problem was that the heater would only blow cold air.

    I found the problem in the wiring between the drivers door and the fuse panel.
    2 of the thick wires that run from the interior fuse panel to the door panel had broken. I had to split the rubber gaitor that sits in the door jam and gently pull at all of the wires one at a time and eventually 2 wires came through.
    It was quite a fiddly job to reconnect but eventually used 2 small con blocks and about 6 inches of extra wire to do all working OK.

    I recently asked another grand cherokee owner if he had any problems of this nature and to my surprise he had THE VERY SAME problem about 6 months ago.

    Suggest you look there first as this sounds very similar.

    I live in England and the fuse for the power windows is 50amp J12 in the PDC under the bonnet but might not be the same on your spec.......This fuse was OK when i had my problem.

    Hope this helps
  • I have a 94 Jeep GCL. All kinds of electical problems. I got a wiring diagram off a site called Scribd. Maybe you can find one on there.
  • Lorraine:

    Sounds like the crankcase sensor is faulty. It's a simple fix, and very common among JGC owners. Vehicle will run fine for awhile, and suddenly stall with no warning. Sometimes, the vehicle will start back up; other times, the vehicle will have great difficulty to re-start.

    I actually purchased a new MOPAR crank sensor on Ebay for $19.00; had a mechanic install it for $60. Been fine for over a year.
  • BartnBetsy:
    Where is the electrical control panel/unit located? How did you come upon that resolution?
  • Bought the JGC new. Runs like a top; 110K miles, and in about as good a condition as a 9.5 year old vehicle can be. I've experienced a few of the electrical issues that many experience, but have managed to resolve all.

    Vehicle has usually been garage kept. However, in October 2009, I left on vacation, and left the vehicle outside for two weeks. Upon my return, I found the gauges not working, all dashboard lights lit up, windows not working. Occasionally, overhead console and power locks don't work. Seems to run fine, and in driving vehicle for last three months, gauges will intermittently come on and off. FYI: When airbag light turns off, speedometer and tach come back on; no other gauges come to life.

    Vehicle has been left with an electrical mechanic; in 7 days, he's found little. Diagnostics trace the issue to the instrument cluster bus, but the ICB seems to be fine; no corrosion, no bent pins, all wires appear to be fine.

    I know that many of you have experienced the issue of non-functioning gauges. Has anyone found a resolution for the problem? Or...any suggestion for things to check? Any help would be appreciated.
