Question about 1998 Ford Explorer

3 Answers

Door ajar light stays on. I checked all of the doors and they are all completely closed and will lock. The keypad entry system will not lock the doors when light is on, I assume because it thinks there is a door open.I do not have an owners manuals to refer to.

The problem is door ajar switch located on one of the door latches just inside the door. what usually works is spraying wd40 or an electronic lubricant prayed liberally into the door latch and then opening and closing the door several times. the stuck switch is usually on the door that is the least used door like the passenger side rear. let us know how you make out.

Check all the switches at the door jambs. Switches can get pushed backward out of their mount or can even go bad or have bad wire connection.

Do you know anything about automotive electronic's ? Control modules ?
Vehicle Security Module
The vehicle security module receives inputs from the following:
  • Door ajar switches
  • Keyless entry keypad
  • Ignition switch
  • Remote keyless entry (RKE) transmitter
The vehicle security module uses these inputs to control an output signal to the instrument cluster which controls the battery saver relay and interior lamp relay. The battery saver relay and the interior lamp relay are internal to the instrument cluster, and are not replaceable. There could be a faulty switch input to the I/C - insturment cluster , causing the vehicle security module to activate the lock's an light's .
Interior Lighting Systems
The instrument cluster grounds the battery saver relay and interior lamp relay coils when any door ajar switch is opened, or the interior lamp (headlamp) switch is closed. The interior lamp relay then supplies voltage to the interior lamp circuit. Vehicle speed must be less than 24 km/h (15 mph) for the instrument cluster to ground the interior lamp relay. The interior lamps remain illuminated for up to 25 seconds after all doors are closed unless the instrument cluster receives an input from any of the following:
  • voltage from the ignition switch.
  • a vehicle speed signal.
  • input from the keyless entry keypad through the vehicle security module.
  • input from the RKE transmitter unlock or panic switch through
  • the vehicle security module.

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.

Keyless entry isn't working and alarm was tripped


Check your door latches. Since the light stays on, one of them isn't reading properly. Once you get that fixed, the remote should work. The light problem could be related. The computer thinks the door isn't shut so that part of the system thinks you aren't moving.

Keyless entry on honda civic 2006 not working


The keyless entry is designed to work with the doors closed (closed - not locked). If the door ajar sensor thinks the door is open the keyless entry is disabled. When you manually lock the door it might tighten the door just enough to activate the keyless entry. I would try slamming all the doors closed and then see if the keyless entry works. If it still wont work have the wiring checked on the front door lock.

My passenger door has no power,my security light is on constantly


Have lost power to the passenger side door. Without power system doesnt recognize door closed because of no power to door ajar switch which keeps dome light on. Security light stays on because without power to rest of systems supplied by fuse it cannot tell if doors and windows closed to engage security features. Most common is for power wire to break somewhere near where it leaves to main body and enters the door.

Door ajar light stays on


go to your local parts store and buy a can of PB BLASTER lubricant then open each door and spray the latch assembley really good then close and open the door 10 to 15 times. do this with each door. the door ajar light switch is located in the door latch assembley and cannot be seen so soak the latch assembleys really good so lube reaches the switch. these switches sometimes get stuck but this usually frees up the switch

"DOOR AJAR" Light Always On... Even with all doors shut... As a result the dome light is always on and "DOOR AJAR" shows up instead of the electronic speedomter so it can be seen how fast the vehicle is...


spray some lubricant (wd40 etc.) into the lock mechanism on the doors .. the switch may be jamming up ..

The front door entry system contains a latch that is fastened to the inside of the door frame and is controlled by the exterior and interior door handles. The latch contains a door ajar switch and a door lock actuator. The front doors can be locked/unlocked by the remote keyless entry (RKE) transmitter, the RKE keypad, the door lock control switch or the door lock cylinder .

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.
