I’ve had the false “DOOR AJAR” warning lamp on my instrument cluster for some time. This is on my 2002 XLT.
This problem is intermittent, but seems to be reoccurring more often now than before. Often enough that I've been leaving the courtesy dimmer switch in the off position for about a year.
From searching the prior posts, apparently it can be either a bad switch or a broken ground wire at the door. Since mine is intermittent, the switch is the likely problem.
If you think your switch is bad, wait until you have the warning lamp and then immediately do the following troubleshooting to isolate the specific door causing the warning, using the alarm and wireless remote entry to set the alarm:
A. With all the windows in the down position, activated the alarm and waited about 30 seconds. Then open one door only from the inside door handle. If the alarm goes off that means that door switch tests OK.
B. Reset the alarm again, trying this on each door. Unfortunately, you can’t do this test on the rear liftgate and rear glass. At least not on my truck.
C. If no doors sounded the alarm, you probably have a problem not related to the switches on the doors or door's ground wires.
On my car, the driver’s door switch tests to be the problem area.
If you think your problem is the ground, checked the wires in the rubber sleeve between the door frame pilar and the door. If any damage is found it should be repaired.
The door ajar switch is attached to the bottom of the latch mechanism. The latch assembly is held to the door by 3 screws and two rods. The screws you could access from the outside of the latch. The rods are hold in place by two yellow plastic clips.
This assembly has two electric plugs one for the lock actuator (the biggest of the two) and another for the ajar switch.
There are several post claiming spraying wd40 through the outside door handle fixes this problem. The switch appears to be sealed so not likely that the spray could get inside the switch. If the warning lamp is intermittent, the spray repair may just be coincidental and actually have no affect. So I suggest replacing the switch.
Here’s how I removed the door panel and the AJAR switch.
1. Remove the plastic cover around the door handle. There are two forward clips, so use a putty knife as shown to pry from the front and then pull out.
2. Lift up the door switch panel from the front and remove. Disconnect the electrical plugs.
3. Remove three screws holding the door panel in place. One screw at the top, two along the bottom.
4. Lift the panel enough to reach the electrical connector to the outside mirror switch. It helps to insert a small flat blade screwdriver between the switch and the plug so as to relieve the detent holding the plug locked in place.
5. Slowly pull back the window liner from the bottom corner enough to permit working inside the door as shown in the photo. Use one of the window wiring plugs to grip the corner to hold it back as shown.
6. Disconnect two latch rods (one vertical, one horizontal) by disconnecting the ‘yellow’ clips. Here's a photo showing the AJAR switch way in the back using an inspection mirror. Annotated is (1) AJAR switch, and (2) the AJAR wiring harness and connectors.
Here's the latch mechanism pulled out enough to allow removing the AJAR switch. I've annotated with the (1) marker pointing to the switch.
7. The AJAR switch can be removed by rotating it 90 degrees toward rear of the latch.
8. Reinstall in reverse order.
After removing the switch, I found I was sent the wrong part. The part they sent is very similar but has a rectangular electrical connector, while the one I need is square. So I have reassembled everything and will wait for the correct part.
Hope this helps anyone with this common problem.
