'03 Expo Electrical Issue! Door Ajar but doors are shut..

[Lazler]

I've looked at the Owners Guide with no help and I've gotta get it fixed! Anyone had this issue before?

Could be bad door ajar switch or the wiring inside driver door boot is broken. It is pretty common, there should be quite a few threads about it.

I had similar electrical issues with my 02 xlt. The dome lights would stay on until the battery saver feature turned them off, 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, etc.

A lot of electrical issues can be traced back to broken/damaged wire(s) in the boot between the body and the door. I found a broken wire and repaired it and all is back to normal!

Could also be related to the door ajar switch.

Here is a great thread for removing the door panel and checking/replacing the door ajar switch, thanks to borland for the awesome write-up: http://www.explorerforum.com/forums/showthread.php?t=249253

That is a great write up.

On a side note, before going through a complete replacement of the switch, you can spray WD40 into the door latch opening on each door, as these become stuck sometimes....and this can alleviate the issue.

This worked for me, after going for more than a year of the "door ajar" light coming on occasionally...mainly after a car wash, high humidity, or rain....making me unable to lock/arm the vehicle from the door keypad and keeping the dome lights on. Worth a try....it worked for me
