Question WJ Electrical Ghost driving me batsh!t... Help?

I have owned my 2003 WJ 4.0 i6 4x4 since late 2012 and have had a few issues with the electrical system, nothing else really though. I have fixed the notorious vac leaks under the battery, near the manifold area etc... fixed the valve cover oil leak and a few others.

1) Courtesy lights (overhead, floor, etc...) sometimes do not come on when doors are opened.
2) Liftgate open illuminates on the EVIC and beeps, no interior lights turn on, and I have to pull over and shut the liftgate.
3) Gauge cluster is illuminated all of the time. Occurred after led interior swap (map lights, license, floor lights, overhead, cargo, glovebox). Converted cluster back to stock bubs, didn't work, so I pulled all of the cluster bulbs so my battery wouldn't die. Brother worked at Jeep dealer last month, he tested the pins under the dash and all modules seemed to be okay. The cluster bulbs weren't in though.

Other annoyances....

4) WJ Jump. Everytime I shift into reverse the thing makes an audible squeak and it jolts. I have replaced the u-joints and did a trans flush and neither helped at all.
5) Passenger mirror mount is broken. Everytime I turn sharply or hit the brakes hard the mirror flies forward. Buying a replacement from LKQ soon.
6) Passenger power seat barely moves forward. It moves about an inch and stops for a minute.
7) Front diff is leaking fluid. Solution. Replace gasket and fluid asap. Lol.
8) Sometimes the power steering makes a loud squeaking/groaning noise when I am turning to park slowly or turning and backing into the garage.

I have read through JeepForum but the posts located didn't really apply to my specific issues. Any help is appreciated, thanks guys!

Have you checked the ground wire that runs between the driver's door and the main body of the Jeep? If it breaks when the interior lights are on they stay on. If it breaks when the interior lights are off they stay off. It impacts power windows, the rear hatch and a few other things. It is the large black wire in the rubber boot between the door and the frame.

As for the gauge cluster deal, no idea on that one...

Start with the ground wire in the drivers door just as Trav1s mentioned. repaired the ground wire in my nephew's '04' and cured several problems. good luck,

Also check the grounds from the alternator to the frame--they get crudded up and/or loose and will drive you nuts. I don't recall if the WJ has a ground strap from the rear of the engine to the chassis, but it doesn't hurt to add a good one.

Power steering noise? If you crank the steering to the stops, it tries to tell you it ain't that happy with you.
