    there is no reset button on the door, there is a metal arm going into door, I believe this is what turns on and off light.

  • philleo Jun 28, 2009

    no such luck found nothing in or around the outside

  • philleo Jun 28, 2009

    I can close door 3/4 of the way before light comes on cannot find any button, or pin like object anywhere by gate or latch

    It's not a reset I am referring to but most have some kind of a button, or pinlike object that the door hits on while closing. Maybe look at outside edge of liftgate door for a spot marked from the contact, or perhaps down by latch area?

I recently had a similar problem with the "liftgate ajar" light lighting randomly on my 2001 PT Cruiser. It was even occurring AFTER I had disconnected the "ajar sensor" on the liftgate. Finally found that 5 wires were broken, one of them the liftgate ajar sensor wire, in the wire bundle that leaves the top of the liftgate and goes into the chassis. I suspect that those broken wires would randomly trigger. Inline spliced the wires and resealed the bundle. Everything looks good for now, although time will tell.

SOURCE: door closed but door ajar comes on

There is a switch or sensor on the door frame either on the hinch side or on the latch side. Try to activate it with the the car on. With the door open, the door open light should light on, if it is a mechanical switch, push it in, if a sensor, touch it with a steel object, the light should turn off. This means the door switch is working ok. Now try the same again but this time push the switch slowly until the door ajar warning light turns on. This means that the switch works ok. Now, close the door from outside and check that there is no gap betwwen the body and the door line all over the perimeter of it. If there is a gap mainly at the latch side or at the hinch side, it can be your problem. If so, let me know so I can show you how to adjust the door to eliminate the gap.
If there is no gaps, your door switch is to low (too far in), let me know so I can show you how to adjust it.

Try spraying WD-40 into the door latching mechanism (door side). I learned this fix after two battery replacements, but have only had to spray twice in the more than seven years of ownership

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.

Rear hatch keeps opens while driving...

Unless you have electrical diagnostic skills , I suggest you take this to the dealer ! The lift gate can be opened by operating the switch on the instrument panel. Battery voltage is supplied to the liftgate actuator through the body control module (BCM). The BCM will pulse the lift gate actuator when a release input is received through the key fob, or the instrument panel switch.
The body control module (BCM) receives an input from the liftgate ajar assembly. The ajar assembly is normally open when the liftgate is fully closed. When the liftgate is opened, the ajar assembly contacts close providing a path to ground. The driver information center (DIC) illuminates the rear access open message when the gate is open. The instrument panel cluster (IPC) receives a serial data message from the BCM indicating the liftgate ajar status. If this message is displayed and the vehicle speed is greater than 8 km/h (5 mph), a chime will sound.
It could be ajar switch is bad .

Can't get dome lights on when door is opener even with override switch off?

The following lamps may be manually turned ON by placing the interior lamp switch in the ON position, or by opening a door while the switch is in the AUTO position.
The dome lamp

The liftgate lamps

Courtesy/map lights

The courtesy lamp supply voltage circuit of the body control module (BCM) supplies battery positive voltage to the dome lamp, the liftgate lamps, and the map lamps. When any door is opened, the door jamb switch contacts close providing a door open input to the BCM. The BCM then provides a ground to the interior lamps with the switch in the AUTO position. The interior lamps receive a ground at G401 with the switch in the ON position.
Important: If the liftgate is opened after all the modules go to sleep, the dome light will not come on. The liftgate ajar switch input to the BCM will not wake up the BCM once it has gone to sleep, so the dome light will not come on. Once the BCM gets an input to wake it up, from remote keyless entry (RKE) or a door handle, the dome light will turn on when the liftgate is opened.
If the driver inadvertently leaves any interior lamp ON, the BCM will turn it OFF after a 20 minute time-out.
The courtesy lamps will turn OFF immediately if the ignition switch is turned to the ON position or approximately 20 seconds after all doors are closed.
The courtesy lamps are controlled by the body control module (BCM). Inputs from the dome lamp switch and the door ajar switches are monitored by the BCM. When a door ajar switch is closed, or the dome lamp switch is turned to the ON position, the BCM supplies the B+ for the courtesy lamps.
With out a factory Tech2 scan tool or equivalent an knowing how these systems work ,you best bet is to take your vehicle to the dealer or some other ASE certified repair shop !

When you open an close the driver door you have no PID change ,right ?

The door ajar input is an input to the Vehicle Security Module , then transmitted over the bus ! You'll have to find a diagram for the med. speed CAN data bus .

My liftgate ajar warning light comes on after car is started. however liftgate is latched. any ideas?

try rolling down a window or leaving a door open, shut liftgate hard. see if it still shows liftgate ajar. on my explorer the seals in door and windows shut so tightly that it was almost impossible to get the gate closed completely with doors closed and windows up.

if this doesn't help then you might need a new switch on it.

When my "door ajar" light was on it was because the liftgate sensors (switches) indicated that the gate was open, even thought it wasn't. I took off the plastic trim, and took out the sensors - but that isn't necessary. Just soak with the switches with silicone spray, and see if that helps. There is one on each side of the liftgate - I believe both must indicate "closed" for the light to go off.

I have gotten replacement motors at Checkers for both driver and passenger doors - so now I have lifetime replacement motors.. The first time you replace them, a little drilling is needed on the door sheet metal, but it will not show up once the trim is reinstalled. This repair is a little involved, but well within the capability of a novice mechanic.

My passenger's door open indicator is on but the door is closed. Where is the indicator located? 2005 freestar. Thanks

Normal Operation When any door or the liftgate is opened, the ajar switch provides a ground signal to the smart junction box (SJB). When the door or liftgate is closed, the ajar switch opens, removing the ground signal. The SJB uses the multiple inputs from the ajar switches to determine whether the doors or the liftgate are in the open or closed position. The SJB then provides a message to the instrument cluster over the communication network. The message center uses this information to display the door/liftgate ajar message.

I suspect your door switch is not closing all the way.

Interior lights will not turn off

get in vehicle and make sure all doors are closed and liftgate and liftgate glass are closed turn on ignition and see if warning of door ajar is on .if so then one of the door ajar switchs are stuck. purchase a can of PB BLASTER available at your local auto parts store and lube all latch assembleys on vehicle then open and close all doors 10 to 15 times this will usually free up the stuck switch. note spray the latch assembleys really good so it will reach the switch which is hidden in the latch.
