Problems with power locks/power windows
 
Today my car started to misbehave itself. I had parked it for 5 minutes or so and when i left again, i saw the interior lights not going out. Only by using the dim switch to completely off, the lights went out. Lateron i found out that also all power windows donīt work, no power mirrors and that also the drivers side door doesnīt lock/unlock when remote or passenger side switch are used. Also the memory seat function is inop. Checked the fuses for the BCM (body control module), but ok. Disconnected the battery for a while to see if that would reset it, but no cure. Seems to be a problem with the drivers side module. Before i will tear down the whole car would like to hear from you guys if something like this already happened with one of you and what finally the solution was.

Ok, my problem is temporarely solved. After some searching on the internet i found out that this problem happened already with quite some other WJ's. Most of the time the black ground wire in the rubber boot between the door and the body breaks. Sometimes the orange wire breaks. Both wires are quite thick and very stiff, the reason that they break after many times being bend when opening and closing the door. I have temporarely soldered the wire ends together and isolated it with isolation tape, but when more time available i want to change both wires for more flexible ones which will not break anymore. :)

I had the same problem with my 2004 Rocky Mountain Edition. I pulled the ground wires and put a compression clamp on the existing wires and then ran a 2nd spare ground wire as a backup...no more problems.

This is exactly what happened to me this morning. I spent some time trying to figure out how I caused it by simply changing some fluids... Just coincidence..

Anyway, 215.00 at the dealership took care of it. I was out of time and my wife was traveling in it tomorrow morning.

I'm going to write a letter to Jeep complaining about this poor design. Tires, brakes, gas, oil.... yes those get used or worn out but wires should last the life of the vehicle!

Thanks for the informative post! I knew exactly what to tell the Jeep dealership and it saved countless hours troubleshooting!

Had that happen with windows on my 99 laredo 4.7 QD. The main control module went bad on drivers side. Power window motor went on passenger door. Main control module was $240 list my chrysler emply. price was 170 which was still pricey. Had a buddy install them every was fine after that.

Re: Problems with power locks/power windows
 
hey so found this thread looking for a reason for some odd electrical issues going on...

1. Driver's side turn signal works intermittently. Mostly it doesn't work, but once in a while it will. From the inside, there is no clicking and no green arrow. NOTHING happens. Its doesn't appear to be affecting the light itself, hazards are fine and brake and tail lights are fine.

2. After that started occurring, now the drivers side window will not roll up. Its stuck down. NO noise, no nothing. I hear no motor at all...

Also, probably unrelated, but the hatch door has never locked, even though i hear the sounds of the mechanism responding to all the door switches and the remote.

I am also having that issue with the oil switch, or gauge cluster, oil pressure gauge goes down in acceleration, back up at idle, or once the vehicle shifts from passing second gear to third. I know for a fact the heads are getting oil, soo i am assuming either a short somewhere in that line or a faulty switch... Note: This is the second switch since the motor swap, bought it at NAPA. I thought the chances of two switches being faulty were slim, but after a friend of mine told me he had two sets of NAPA plug wires be faulty, im not so sure...

Any opinions guys? My bf is worthless... and I know jack about electrical...

Intermittent electrical problems are most of the time related to bad contacts/broken wire/ground problems. There is a combination flasher unit under the drivers side dash, but it acts for turn signals as well hazard lights. It is an electronic controlled relay, so maybe the problem is in there. If it was wire related, the problem should be there for the hazard lights as well. Did you check the lights outside if they really work when hazard lights are switched on?
Regarding the window motor, did you check the fuse? If ok, many other things can be wrong. The Driver Door Module, the window motor itself or wiring. If fuse is ok, i would first check the wires in the boot between the door and the body for any broken wire. If this is ok, you will have to measure on the window motor connector to see if power is there.
Regarding the hatch door lock, there most probably the lever connecting the actuator to the actual lock has become loose.
And the oil sensing unit, when your sure that the oil pressure is ok, i would try an original Mopar unit.
And then your last problem, your BF, just trade it in for a more usefull one:D.
