If the above didn't work, spray the latch with a electrical cleaner and follow with a silicone spray. Works almost every time...

Try spraying wd40 or any rust penetrant into the door latches. Open and close the doors several times to unstick switches.

Your best bet would be to find a Tech like this guy , with the right diagnostic equiment . Door Locks Go Crazy 1 Unless you know how to do automotive electrical testing . Your door ajar switch is a input to a body control module . or GEM as ford calls thiers .
Door Locks Go Crazy 2 Your auto lights are controlled pretty much the same .
Electric Testing Techniques You Need to Know

Do you know what DTC"S are ? diagnostic trouble codes ! You probably have a door ajar switch problem . You need a factory or professional type scan tool to check these codes
B1322 Door Ajar Driver Circuit Short to Ground GEM/CTM REFER to Section 417-02 . B1323 Door Ajar Lamp Circuit Failure GEM/CTM REFER to Section 413-01 .

  • Light sensor amplifier.
  • Go To Pinpoint Test H .
  • The Autolamp Time Delay Is Inoperative
  • Fuse(s).
  • Light sensor amplifier.
  • Headlamp switch.
  • Circuitry.
  • VERIFY parking lamp operation. If OK, REPLACE the light sensor amplifier. If any parking lamp concerns exist, Parking, Rear and License Lamps REFER to Parking, Rear or License Lamps.

Do you see how complex these systems can be for someone that doesn't deal with these problems on a daily base's ! Check for codes an if there are any , doing the diagnostic's associated with it . Without doing the diagnostic's you could replace parts all day long an not fix the problem .

How to diagnose which door is causing the door ajar warning on dic for 08 pontiac g6 4cyl 4dr


It should tell you which one .
Driver Door Ajar Malfunction
Passenger Door Ajar Malfunction
If not a scan tool would be the best way.
Ignition ON, observe the scan tool Driver Door Ajar Sw parameter while opening and closing the driver door. The parameter should change between Door Closed and Door Ajar
? If the parameter does not change, refer to Driver Door Ajar Malfunction.
With the passenger doors closed, observe the scan tool Door Ajar Switch parameter while opening and closing each door. The parameter should change between Door Closed and Door Ajar.
? If the parameter does not change, refer to Passenger Door Ajar Malfunction

Ignition OFF, disconnect the harness connector at the driver door latch.
Test for less than 5 ohms between the ground circuit terminal 8 and ground.
? If greater than the specified range, test the ground circuit for an open/high resistance.
Ignition ON, verify the scan tool Driver Door Ajar Sw parameter is Door Closed.
? If not the specified value, test the signal circuit terminal 6 for a short to ground. If the circuit tests normal, replace the BCM.
Install a 3A fused jumper wire between the signal circuit terminal 6 and the ground circuit terminal 8. Verify the scan tool Driver Door Ajar Sw parameter is Door Ajar.
? If not the specified value, test the signal circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the BCM.
If all circuits test normal, test or replace the driver door latch

2002 ford explorer xlt overhead lights not turning off. I have replaced the 2 front door ajar switches and everything worked. However, I pulled up and parked and the overhead lights would not go off.


Which overhead lights ? Just the dome lamps . If there is no door ajar light lit on the dash . There could be a problem with the G.E.M - Generic Electronic Module . You should have it check for DTC'S - diagnostic trouble codes . Need a special scan tool ,a OBD2 code reader won't do it.

2002 lincoln towncar door ajar light s stay on after minor accident. Only goes off when in drive. Can't find the fuse. I have to disconnect the battery


You have one or more door ajar sensor switches that are defective, have the BCM (Body control module) scanned to see which door is causing it, the light can be turned on by any of the 4 doors. The sensor is located inside the door on the door latch mechanism, there is no fuse as it is a ground circuit.

  1. NOTE: The generic electronic module (GEM)/central timer module (CTM) must be reconfigured upon replacement. Refer to the scan tool help screen on the configuration card to program the tire size and axle ratio.
    The warning lamps are a GEM/CTM controlled system; refer to Section 419-10 .
  1. Verify the customer concern by operating the system in question.
  1. Visually inspect for the following obvious signs of mechanical and electrical damage.

    Visual Inspection Chart Mechanical Electrical
    • Switch(es)
    • Fuse(s)
    • Damaged wiring harness
    • Loose or corroded connections
    • Circuitry
    • Bulb
  1. If the concern remains after the inspection, connect the scan tool to the data link connector (DLC) located beneath the instrument panel and select the vehicle to be tested from the scan tool menu. If the scan tool does not communicate with the vehicle:
    • check that the program card is properly installed.
    • check the connections to the vehicle.
    • check the ignition switch position.
  1. If the scan tool still does not communicate with the vehicle, refer to the New Generation STAR Tester manual.
  1. Perform the DATA LINK DIAGNOSTIC TEST. If scan tool Tester responds with:
    • CKT914, CKT915 or CKT70 = ALL ECUS NO RESP/NOT EQUIP, refer to Section 418-00 .
    • NO RESP/NOT EQUIP for GEM/CTM, go to Pinpoint Test E.
    • SYSTEM PASSED, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs and perform self-test diagnostics for the GEM/CTM.
  1. If the DTCs retrieved are related to the concern, go to the GEM/CTM Diagnostic Trouble Code (DTC) Index to continue diagnostics.
  1. If no DTCs related to the concern are retrieved, proceed to Symptom Chart to continue diagnostics.

Car ajar light and alarm goes off on 2005 tribute


Pits one of the five door ajar switches. They are located in the door latch mechanism that holds the door closed. The best way to figure out which one it is is to scan the body control module. With all the doors closed. It will tell you which door is giving the open signal. This will need to be done with a high end scan tool that any good shop or the dealer will have. The most common one to fail is the driver front door.

Door ajar light stays on


Why is it that a door can be ajar but a jar cannot be a door? - Always wondered about that one....:)

On a more serious note: Ford Explorers are notorious for the door ajar switches going bad. I have seen them com on by themselves when the vehicle is parked and cause the battery to go dead because they will turn the dome lamps on also.

Most of the time it is the driver's door that has the problem, but ANY of the doors COULD be tha cause. It would be best to scan the computer system and look at the Generic Electronic Module (GEM) data to see which door is showing "open" when you have all the doors closed. Otherwise, you may have to disassemble ALL of the doors to find the culprit if replacing the switch in the driver's door does not fix the problem. The first picture below shows the switch itself. The second picture shows how the switch is mounted in the door latch mechanizm inside the door panel.

Door ajar light stays on


A door ajar switch is probably bad but some suggestions say to open the door spray the latches with some penetrating oil open and shut the doors a few times.Sometimes this method does work temporarily. The best solution would be to hook up a scan tool that is capable of determining which door it views as being ajar.Some of these models have just a door ajar switch attached to the the door latch mechanism others may require the door latch to be replaced.

Is there a fuse or relay that can be blown by lightning?


Obviously all the sensors that control everything that is lighting up in your vehicle are not communicating correctly with the vehicle's computer. You can take your vehicle to your local autozone, they will scan and reset the computer codes for you for free. If that doesn't correct your issues, I would replace the vehicles computer.

Door ajar light in dash is on along with interior lights


the door switches for that year explorer are actually found inside the door panels, built into the door latch. they are a real pain to change out. the only way really to determine which door it is (it could also be the rear hatch) is to use a scan tool to view door ajar data, then change that one switch.
