Electrical problem

I got a 02 Taurus SES with a big problem. Sometimes, when I open the drivers side door to get in, and close it, the lights will not go off, and I have that annoying idiot light on the dash telling me a door is open, and I know that all the doors are closed. Then a few days ago, it started doing something weird. None of the windows would go down, the moonroof wouldn't open, the power locks stoped working, and I had no lights. But after opening,, and closing the door several times, everything would work fine. Any ideas what the problem could be?:banghead:

There is na electronic sensor in the door that tends to stick. The correct way to fix it is to replace the sensor. I have heard of other ways though.

Well, it's not an electronic sensor in the door, just a switch. You can do a search in the forum for "door switch" and find more info than you probably want from that search.

The windows, locks, etc. failing to work, I would expect that to be unrelated to the door ajar indication. When you say the lights wouldn't work, was that just the interior lights that come on when the doors are opened, or does that include headlights, etc. as well?

If it were just windows and locks, I'd suspect the problem to be in the connector junction in the door jamb near the hinges. However, I wouldn't expect the lights and sunroof to be effected by that junction. Instead, you might have an issue with a loose fuse, loose connector at the Generic Electronic Module (GEM) or intermittant GEM. Inspect the fuses in the engine compartment and interior to make sure the all look properly seated.
