Where is the 2003 ford expedition door ajar switch location?

Answer 1

The door sensor is an integral part of the door latch mechanism. The sensor cannot be replaced independent of the latch. A sensor appears on each of the four doors, as well as the tailgate. WD40 sprayed on the sensor sometimes frees it up (you must remove the interior door panels to access -- it's part of the latch and difficult to see because it's well hidden inside the door), but just as often, WD40 won't cure it. You can also remove the 15Amp fuse in position 14 in the box located beneath the driver's side of the dash. This will disable the interior lights as well as the running board lights (good), but it also disables the power windows (bad). This will, however, solve the problem of the lights remaining on after the doors are shut and running down your battery. The only true fix is the replace the affected latches. They sell for approx. $55 on the Web, and unless you're mechanically inclined, and very patient, you should have the dealer do it for you (expensive). Malfuntioning door sensors are a very common problem on Expeditions, Explorers and Windstars.
