03 limited electrical problems?

[kylev90]

2003 (build date 12/02) limited 4x4 explorer. The alarm is going off randomly. No clue there. Also, the entry button pad on the door is not working. I was told the code is under the interior panel by the passenger side rear seat. Tried that, and nothing. I dont think its working at all though because the buttons dont light up or anything. Final question: key fob does not work. Do i just take it to a dealer to have it reset? sorry for long post. Thanks

this probably wont help but check your wiring under the bonnet for rodent activity (gnawed insulation, nesting on the manifold) can sometimes cause dramas that wont show on a diagnostic because its too intermittent. sorry man i dont know about the fob. have a good one and hope you get it sorted

I had a similar issue 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 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

Here is the procedure for programming the key fob:
