I have ran this question on 3 other forums with literaly no inteligent response.
I have a '98 ZJ Laredo SE which I converted to 4wd about 2.5 years ago. The Laredo SE has a majority of the "hot" options, which is everything but a sunroof, garage door thingy seat heaters and seat memory.
Here is the problem. I have an intermitent short. The fuse (#16 if i recall) for the overhead console also runs the turn signals. It will blow at various times. Never the same time twice. I have replaced the multi function switch, and unpluggled a few items to include the overhead console. No worky. Even with them unplugged, it will still blow.
The scenario is that I can put in a good fuse. Start up the Jeep and let it run for 10-40 minutes. At a random point, the fuse will blow rendering the turn signals and overhead console usless. After THAT point, if the Jeep is not shut down, the attempt to plug in a new fuse results in an IMMEDIATELY popped fude preceeded by a severe load... interior lights dimmed, volt gage dropps...
But if the Jeep is shut down for any amount of time, the whole thing goes again. I have gone once for about days with no problem, but then it starts over.
Basically, I have torn down the entire rear of the Jeep (front seats to the rear gate) and traced the main wiring harnesses. No shorts found. No burned wires. I have also traced the wires via a copy of the related diagram from a FSM. No luck.
Here is one kick. I found that the fuse also runs power down to the neutral safety switch on the tranny. At one time, I unplugged the switch, and ofcourse, the Jeep would not start. I plugged it back in, and drove it for 4 days before the fuse popped again. To what, exactly is powered down there, I ain't sure. But, even with the fuse blown there is no change in the way the ZJ runs for the most part. It is hard to note a loss of power since I am running 33's and 4.56 gears behind a 4.0, so I cant really know for sure.
I have spoken to two friends who are affiliated with Jeep factory service departments. Both agree that there is a computer controlled or switched component that is causing th e problem, but we cant pin-point it. There is no turn signal short since the emergency flashers have worked flawlessly prior to and throughout this problem.
I figured I'd ask here since the ZJ and XJ systems are failry similar.
Any good assitance is GREATLY appreciated.
