Inside lights

2002 ford windstar door ajar light will not turn off. All doors are close.

Remove "Door Ajar" switch. Clean the switch and use a graphite type lubricant (I recommend "Dry-Slide") to lubricate the actuator on the switch. Reassemble the switch.

The switches are located inside the door panels, attached to the catch mechanism.

1) Remove interior door panel.

2) Using a T-27 Torx driver, remove the 3 bolts holding the catch in the door.
2a) The door ajar switch is the only part on the mechanism with the 2-wire harness.
2b) The switch is located at the rear catch for the sliding door.

3) Using a small flat screwdriver, gently lift the black tab on the catch mechanism and rotate the switch to remove it from the catch assembly.

4) Using a rag, clean the small round actuator and apply a small amount of graphite lubricant to the actuator and work the switch so it moves freely.

5) Reassemble the catch and the door.

my 2003 ford windstar door ajar light wont turn off either. and all doors are closed

I had this problem and my mechanic looked everywhere finally discovering the wires in the top of the van were making contact against the roof and causing the lights to come on. Good luck!

Before you start taking the doors apart, try spraying something like"WD40" or another spray lubricant into the door latches. Pay special attenton to the sliding door, there are two latches, one in front and one in the rear.
