The X's alarm does not arm at all, even when I make sure all doors and windows are locked. It may not have one though, because it was a state government vehicle. I'll look for signs of it.

The only time I get a door ajar bell or chime is when the driver's door is open with the key sitting in the ignition amd with the key in the forward position but not cranked. When X is cranked no doors make a chime come on.

No other doors start or stop the ajar chime, only the driver's door.

 

I have a 2001 X 5.4L 4wd XLT that I bought recently. 155,000 miles. Maintained very well by a state agency. First Ford truck for a long while.

I can't find a DIY procedure to figure out what door or door switch/wire is causing my "door ajar" dash light to come on as well as all of the interior lights.

The interior lights go off after 10-15 minutes but do it again almost everytime a door is opened, apparently any door at times, but sometimes none of them. I thought it was the Driver front door or rear glass or cargo doors (most used) but the light will come on and stay on with the X off, key in accessory position, or with the X cranked in Park or while driving.

Also, I don't have a door ajar chime at anytime other than initial key insertion and crank. And my alarm will not arm either...I always get 2 beeps instead of 1 beep with remote (this may be the manual door locks fault though... I'll I check this out today).

Only the driver door and back glass/cargo doors power door lock and unlock correctly. The rear driver door will go down but not up with cab button or remote, and the passenger side front and rear doors don't do either. They all function manually though just fine. I attribute the door locks to old actuators but I haven't pulled any door panels yet (actually I don't care about the power door locks anyway). All the windows work fine with all window switches and power mirrors work fine also.

I've soaked all the door latches with rust penetration oil three times over the last 3 days and actuated the doors both manually with a screwdriver and by opening/shutting the door at least 60 times each. I've push and pulled on the shut doors and with screwdriver with doors open. No difference.

Is there a secret code or procedure to isolate where the switch or wiring problem is?

The interior lights will stay on for the same amount of time when driving it as well. Not a big deal in daytime but a big deal at night because there's no interior lighting override for my XLT (rubber floor and cloth interior).

Thanks for the help! willie

 

I unplugged both switches and the light is still on not sure how that's possible could use some input and my driver's side window has intermittent issues of going down not sure if that is related to the door adjar light
