    I'm having the same problem. I noticed it happening mostly when the car got wet (carwash, or good soaking rain) at the beginning. It's been a few months now and it seems to be getting more and more sensitive and tempermantal. While all doors are closed, the door ajar light on the dash comes on and my interior lights come on, then I can't lock it because when it's armed and the light comes on, it sets off the alarm. I've since turned them off, hopefully saving the battery a little.

    I've been told that it could be a bad door sensor. Do anyone know how to check or how involved it is to test these and replace any that are bad?

Hi, my name is adam. By the way your descrpion says, you are having difficulty with the door ajar. My solution is to take a pink eraser and clean off the sensors on each door. Sometimes road dirt and grime get in there and screw it up. Thank you.

Door ajar light keeps coming on when door is closed tightly

The problem is a dirty switch. use a can of wd-40 or equivalent and spray the door latch heavily. Next hold up on the door handle and work the latching mechanism back and forth really fast. Next repeat the process 2 or 3 times. It only takes a few minutes and your door latch sensor will be working like new again.

This is not a good thing. Ford uses a computer called the GEM and that means General Electronics Module. It controls:
  • Low Coolant Indicator On Cluster
  • Brake Indicator on Cluster
  • DRL - Control
  • Wipers
  • AutoLamps
  • Rear Defrost
  • Interior Lamps(dome)
  • High Beam Indicator only (cluster)
  • Low Coolant indicator
  • Key-in Buzzer
  • Seatbelt indicator only (Cluster)
  • Trunk Pop Relay
  • Power Locks
  • Door Ajar Sensors
  • Door Keyless entry pad
  • Remote Keyless Entry
  • One Touch Down (power window)
  • Air Bag Tone
  • Anti Theft (perimeter Alarm) (SEL, or SE(s) with mods)
  • Lift gate ajar (wagon)
  • Liftgate Pop
  • Accessory Delay signal (accessory that work after engine off, prior to door ajar)
  • Battery Saver Relay signal (accessory that work after engine off, 15 mins) Map lights, vanity mirrors

They are located behind the radio in the dash and they are $$$ about 600 USD.

Door ajar light

I found that when I opened the right rear door several times I could get the problem to clear. Once I got the problem to clear I tired to keep any one from using that door. Once they forgot and opened that door again I was back in trouble again! I finely replaced the switch in that door and problem was corrected. Wish you luck this can drive you crazy..

Hello. I have a 2000 Mitsubishi Montero Sport. The rear door/hatch no longer stays closed tight enough, so the door ajar light flickers on and off. As a result, my alarm goes off at random times. Could...

The better solution is to fix the hatch so it closes tightly. The latch hooks on to an adjustable loop. The hatch closes on to the rubber seal: if this is damaged, fix or replace. There may be some adjustable rubber bump stops as well. Lastly, check that the door ajar sensor is not loose.

Ignition alarm will not stop 97 ford f150

The key switch usually breaks or wears out and makes contact. It is on the lock cylinder. This would cause the chime to not come on, or stay on. Sounds like the switch is bad.

1997 F-150/250 Warning Chime, Key-In-Ignition The key-in-ignition chime warns that the key is still in the ignition when the driver's door is ajar. The key-in-ignition warning chime will sound when:
  • GEM: Driver door is ajar, the ignition switch is in the OFF/LOCK or ACC position and the keys are in the ignition.
  • CTM: Driver door is ajar, the ignition switch is in the OFF/LOCK, ACC or RUN position and the keys are in the ignition.
The key-in-ignition warning chime will stop sounding when:
  • Driver door is closed.
  • Key is removed from the ignition.
  • GEM: Ignition switch is switched to the RUN position.
The key-in-ignition warning chime inputs are:
  • Ignition switch RUN position (battery potential on both RUN and RUN/ACC inputs).
  • Ignition switch ACC position (battery potential on RUN/ACC input only).
  • Key-in-ignition switch (grounded with key-in-ignition, open circuit with key-out).
  • LH door ajar switch (open circuit with door closed, grounded with door ajar).
This is a pic for a 98, could not find one for 97 which may be the older style which is more prone to break.

Door lock staying locked so door cant clamp on to the striker

Hello and welcome to FIXYA, it sounds like you have two problems, first the door ajar switches in your truck are sticking, and causing the ajar light to remain on, and second the door lock actuator is shorted and getting stuck in the lock position. To repair the switches, obtain a can of brake cleaner and spray the door latch of each door for about 3 to 5 seconds, then open and close the door 10 times to work the cleaner into the switches. To fix the lock problem, you must first pull up on the knob in the door panel to unlock it. Then remove the door panel, and replace the door lock actuator.

2003 Explorer door ajar light stay on when all doors are closed

I had this problem on my 2003 explorer and took WD40 and gave the lock mechanism a good dose where it meets the clasp on the door jam. Then open and close the doors a couple of times to get them working. They get gummed up and sometimes have a tendency to stick.
