I found that if you spray some penetrating fluid (not WD-40) such as move-it or liquid wrench on the switch, it will repair the problem. You spray the fluid on the switch and open and close the gate repeatedly for about ten times and the contacts will be cleaned and working again. This also works for the doors. The switch is located in the latch mechanism so spray the fluid in that area.

-----------------------------------------------------------------------------------------

Principles of Operation
The power liftgate is controlled by the power liftgate module.
The power liftgate module receives inputs from:
  • glass position switch (determines the ajar status of the liftgate glass).
  • forkbolt switch (determines the primary position of the latch).
  • detent switch (determines the secondary position of the latch).
  • home switch (determines the power cinch status).
  • power liftgate control switch (activates the power liftgate from the interior of vehicle).
  • pinch strip switches (determines if an obstacle is detected between the pinch strip and liftgate).
  • instrument cluster module (activates and sets the options for the power liftgate).
  • optical sensor (determines the direction, travel speed and obstacle detection of the liftgate).
  • UBP serial communication link.
The power liftgate module sends outputs to:
  • liftgate motors.
  • power cinching latch system.
  • liftgate chime module.
  • body security module
------------------------------------------------------------------------------------

The liftgate consists of the following components:
  • liftgate window glass latch
  • door lock actuator (power liftgate only)
  • liftgate latch
  • liftgate handle
  • liftgate latch remote control (power liftgate only)
  • liftgate ajar switch
  • chime module (power liftgate only)

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.

Liftgate ajar is on


There are 2 switchs one each for the left and right liftgate latch, u must detrim the liftgate to replace them, they stick and cause your problem, replace the courtesy light switches on both latches.
