Door ajar, courtesy lights problem

[Thub]

on my 2002 xlt it has become an clear issue that when the front passengers door is opened the dome lights and side mirror lights do not come on, I guess the truck thinks the door is still closed. This problem does not happen every time but I think the cold/wet is messing with the sensors. I am wondering if it is the "door ajar sensor" fix that is buried behind all the latch assembly stuff, the truck has not been doing the door ajar alarm when running and all doors closed, I guess it is "frozen" in the closed position. Could washing the truck today have affected the sensor? I pulled it in the garage tonight to let it stay dry over night just in case.

Could be related to the door ajar switch.

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

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

Hope this helps out!!
