My XJ, like many of yours, has been used and used hard. I'm now having issues with fatigued wires going from under my dash / under the hood into the driver side door. Currently the power locks do not work (they were off and on for a while and now have been off for about a year) and now the power windows are starting to go as well. The power window issue can be solved by josteling the wire pack going into the door but I do not feel like doing that every time I need to put down the windows.

I need to get in there and fix the fatigued wires. Has anyone else done this? Any advice on how to fix this? I have a power tester but I think I'll be able to see the issue wires easily enough. I've never taken the door apart so any quick tips or words of caution here would be useful as well. Thanks!
