Wonder if its been under water.... havent looked at my wiring diagram, but i'd lean toward a common plug with corrosion,etc....best case. could be all over if Its a flood car

if you find a common thread like a plug, try some wd40 if its got chalky white/green stuff on it before you start yanking it apart.

just some general ideas.....good luck!

Not under the hood the one under the dash driver's side. There is fuse on the back of the stereo also if it's stock. Could be a common denominator like an unplugged harness. Since you don't know the timeline of the failures you just don't know. Check the fuses first, won't' cost you any money.

I've had similar problems on my '01 XJ. The power windows and locks were intermittent, and I traced the problem to about six broken wires in the harness between the driver's door and the interior. This is a common problem on XJs, I understand, but I don't know what range of years. The breaks occur in the area protected by the rubber boot between the door and frame. To remove the harness I had to remove the interior door panel, the water barrier (a thin sheet tacked up on the door), and the driver's kick panel. The harness itself wasn't that hard to remove. Once I got the harness on the table and removed the protective cover, 12 broken and corroded wire ends popped up at me. Fortunately everything was color coded and easy to fix.

If you're handy with a VOM (multi-meter) you can check continuity on the wires by removing the interior door panel (disconnecting the connectors at the window switches) and the kick panel where you should find the other end of your harness. Shoot the wires and if any of them are open (no reading on the VOM) you've got a broken wire. Remove the harness and see what you've got.

The power mirrors also go through that same harness, but your other lights and the radio are controlled elsewhere and I can't help you with that.

Good luck.

So i checked out the area you spoke of monty and there was no broken wires. So, I pulled the wire harness for the drivers side door and found some coroted(however you spell it) wires. I'm in the process of making a whole new harness for it.

Corroded wires might do it, also. Funny thing about electrical problems is that they can be affected by a number of factors.

If you have a multimeter, I'd shoot those wires just to be sure.
