Probably the switch input to the BCM is bad . door ajar switch .
The BCM is also capable of commanding other vehicle systems to control functions that are not directly wired to and/or controlled by the BCM. The BCM accomplishes this task by sending specific messages on the class 2 serial data link. The vehicle system capable of performing such function will respond to the BCM message.
The BCM controls/monitors the following functions:
• Audible warnings
• Indicators control
• Interior lighting
• Exterior lighting
• Power/automatic door locks
• Keyless entry
• Content theft deterrent
• Personalization
• Serial Power Modes
• Electrical Power Management

Audible Warning
The body control module (BCM) provides the following audible control functions. Some audible control functions may be controlled by other systems through the class 2 serial data link:
• Headlamp on reminder
• Key in ignition reminder
• Personalization mode
• Delay locking indication
• Keyless entry programming/diagnostic mode indication

Indicator Control
The body control module (BCM) provides the following indicator control functions through the class 2 serial data circuits. Some indicator control functions may be controlled by other systems through the class 2 serial data link:
• Door ajar
• Liftglass/endgate ajar
• Park brake
• High beam
• Park lamp malfunction
• Service vehicle soon
• Personalization mode
• Security LED

Probably the door ajar switch on the door lock is bad. don-ohio

The body control module controls all of your freaky problem. Replace that.

one of the door ajar switches are sticking. needs to be put on the computer to find out which one. only other way is to go around and unplug the switches until your light shuts off.

The door lock relay or one of the door sensors/ switches is defective.

one of the door/van loading door switches has failed it thinks a door is open so the the interior light stays on and the door open warning will ding the interior light should have a switch to disable it or take out the bulb but you cant stop the dinging until you find the faulty latch switch and fix it

open the door and there will be a small piece of plastic that can be pushed into and out of the door jamb. You will need to replace that because it is not telling the computer the door is shut.

sound like your fluid sensor may be stuck or bad if light stays on try tapping the washer motor on the resevoir if it goes out faulty sensor as for the door ajar light it might have bad connection with sensor saying the door is closed local dealer should be able to troubleshoot sensor

I had the same problem in my 98 and 96 Sables. Ford dealer says it is a problem with a sensor, located behind the left rear quarter panel. It doesn't recognize when the doors are closed, therefore it leaves the dome light, etc. on--sometimes briefly, but possibly until the battery goes dead. Worse when the weather is damp. Their solution was to throw it on the diagnostic computer BUT ONLY WHILE THE PROBLEM IS ACTIVELY HAPPENING, then replace the sensor--they quoted me a minimum of $300. I leave the cover off the dome light, and pull the bulb when necessary.
