Door Alarm/Door Ajar

[SSmitty]

I have had a problem with the door alarm going off while driving along with interior lights coming on while driving and in park with car turned off. I was able to determine it was the passenger side front door causing the problem. The dealership wanted $352 to fix it. With the help of the internet I was able to fix it myself. The part is XF2Z14018AA. Sorry I didn't take pictures while doing the fix but it wasn't that hard to do. After taking the door panel off, remove the door latch with wires and cables still attached, unplug alarm switch. To remove turn CCW and it will unsnap, NOTE: Passanger side CCW, Driver side latch CW. Pop the new swith in and reassemble. BTW I did try lubrication of the door latch with WD40 first to see if that would cure it, no luck.
Hope this helps someone else with the same problem. This forum has helped me with other fixes. I did search this forum but did not find a post on this particular problem.

How do you decide what door is causing the problem?

If the door ajar alarm is on and you are parked spray WD40 in one door lock at a time, give it about 2-5mins before you move to the next one. That is how I determined which door was causing my problem.
