Strange electrical prob.

I recently (yesterday) changed the door pin switch in the drivers door, many thanks to this forum. While the door ajar light and painfully annoying beep was ruining an otherwise peaceful commute, i would keep the interior light switch, the rotary, in the off position. New pin switch is in, no more door ajar, no noise, all good.
Last night i notice when i get out of the car, no mirror light. And interior lights do not shut off. So i play around with it for a little while and this is what happens:
With the rotary switch in the off position, car off, the lock button on driver door doesnt work. Keypad on driver door will open locks but not lock them. No mirror lights and interior lights are off. No lights on keypad either.
With rotary switch in on position, driver door lock button works,keypad locks and unlocks but only lights up for two seconds. Still no mirror lights and interior lights stay on until battery saver shuts them.
Its a riddle wrapped in a conundrum.
Any ideas?

I suspect you have a or several broken wires in the door harness. Remove the rubber boot and inspect each wire and repair...

Welcome aboard!!

I agree with jp450. Having said that:

I had similar electrical issues with my '02 XLT. The dome lights would stay on until the battery saver feature turned them off, the accessory delay wasn't working, the driver side puddle light didn't work, the keypad on the door would set off the alarm when I pressed it, the door ajar light would flash and beep at highway speeds, the radio would shut off as soon as I turned the key off, the alarm would beep twice when I armed it. Recently all 4 windows stopped working. Most recently the driver door lock actuator stopped working.

A lot of electrical issues can be traced back to broken/damaged wire(s) in the boot between the body and the driver's door. I found 3 broken wires and repaired them. The thin black ground wire was broken and after repairing it all was back to normal. When the windows stopped working, I repaired the thick black ground wire and the windows now work like a champ. I had to repair the pink/black wire to fix the driver door lock actuator.

Here is a great thread for checking for broken/damaged wires, thanks to synyster for this awesome write-up: http://www.explorerforum.com/forums//showthread.php?t=270081

Be sure to take your time when looking for broken/damaged wire(s). Check all the wires for breaks/damage. When you think you're done looking, look again, and again, and again. A bright flashlight can be very helpful.

Good luck with the fix.

Please keep us posted as feedback helps others reading this post looking for a fix to the same or similar issue!

I havent had a chance to inspect the wiring, but i did notice one other thing. With the rotary switch in the on position, when i shut the engine and pull the key, the radio shuts and lights come on. That would normally happen with an open door. But there is no indication of an open door.
