You have a problem with the switch in the ignition responsible for sensing ignition key, the switch is stock on.

The warning chime sounds if the parking lamps (13200) or the headlamps (13008) are left on after the key has been removed from the ignition switch lock cylinder and either front door (20124) is opened. There is a chime module that controls this .
The safety belt warning chime (10D840) (also called the central processing unit or CPU) is an audible warning system and timing circuit. The system components include:

• Timing circuit safety belt switch.
• Dome lamp switches.
• Safety belt warning indicator switch which is an integral part of the front safety belt buckle end (61203).
• Ignition switch (11572).
• Headlamp switch.

The warning chime sounds and the safety belt warning indicator illuminates when the ignition switch is placed in the ON position and the LH front safety belt is not buckled.
Key In Ignition Warning
The warning sounds if the key is left in the ignition switch lock cylinder when either door is opened and the ignition switch is in the LOCK or OFF position.

Bad door switch, or it may be dirty and "stuck" in the recessed position as it would be when the door is closed. I find WD-40 or equal is a good solution for this. Otherwise the switch's connections are bad (corrosion) or the switch itself is bad. More extreme is a break in the wiring to the switch and or connection near the fuse.

I just found out that the problem on our 1998 windstar was the chime switch attached to the ignition switch. This chime switch when dislodged will short and act as if the keys are still on when the door is open ( thus sounding off the alarm). I had a hunch that the problem was close to the steering wheel because the alarm would stop if I change the angle of the steering wheel a couple of notches up or down. I guess when i did that the chime switch that i'm pertaining to get reset to the right position and stops the alarm. when i opened up the steering wheel housing around the ignition , the chime switch fell, it had a blk wire I think, and I saw that the clips on it were kind of melted thus not sticking to its right position. I just had to remove the ignition switch for a while and replaced the chime switch with the help of a zip tie wrapped around it. then I placed every part back together and no chimes... also I did this all while the battery was disconnected because i needed the ignition switch to be in the on position to get it off the steering wheel. Good luck guys!

This alarm was placed in the vehicle for the purpose of not leaving your keys in the ignition while getting out and locking the door.
If in fact you wish to disable this safety function (and possibly one day lock your keys in the vehicle) Look under the dash, drivers side, while the chime is activated. You should be able to locate where the beeping sound is coming from and unplug the chime.

Hi John,

Had a similar problem with my Saturn. Door chime going all the time, the seat belts going up - down - up for no apparent reason.

Turned out to be the switch in the door jamb had become unseated. As it randomly made and broke contact, the cars computer thought the doors were opening and closing, then acted accordingly.

I remounted it with the help of a hot glue gun (plastic mount).

Hope this info helps with your problem.

Best regards
Mike

key chime sounds if the little tab is grounded where the key contacts it. The theft light is supposed to blink when the system is armed to let you know it is armed. That's normal.

What do you mean by auto door locks won't unlock? The remote doesn't work? the door lock/unlock button on the door trim panel? Do they lock ok? Or, just unlock doesn't work?

NOTE: The generic electronic module/central timer module (GEM/CTM) is connected to the ISO link and is diagnosed through the data link connector (DLC) with New Generation STAR (NGS) Tester.
There are five warning chimes and lamps the GEM/CTM controls: headlamps operating without the ignition on (chime only), door ajar (chime and lamp), key-in-ignition (chime only), driver seat belt warning (chime and lamp), and message center.


Audible Warnings Warning Condition Lamp Duration Audible Duration Audible Output Safety Belt 60 Seconds 6 Seconds Chime, 60/Min. 740 Hz Key In Ignition — Continuous Chime, 120/Min. 740 Hz Headlamps On — Continuous Chime, 240/Min. 740 Hz Door Ajar Continuous 1 Second Single Tone, 1000 Hz Message Center (Tone Request) — 1 Second Single Tone, 1000 Hz
When the is turned to RUN or START from OFF or ACC, the chime will sound for six seconds or until the safety belt is buckled.
The will turn on for 60 seconds or until the driver safety belt is fastened. Both the chime and the lamp turn on at the same time.
If the safety belt is buckled before the ignition switch is turned to RUN or START, from OFF or ACC, neither the chime nor lamp will be activated.
Anytime the is changed to RUN from START while the safety belt warning indicator is activated, the safety belt warning indicator will remain activated until either the timing sequence has been executed or the safety belt is buckled.
When at least one door is ajar and the key is in the RUN position, the door ajar cluster lamp is activated and remains on until all doors are closed. A warning tone will sound once any time the key is in the ignition switch and any door is open.
The key-in-ignition warning will sound when the driver side is opened with the key in the and the in OFF or ACC. It will continue to sound until the key is removed, the is closed, or the is in RUN or START.
The headlamp-on reminder chime will be activated if the headlamps or parking lamps are on, the key is not in the ignition switch, and the driver door is opened.
A single tone will be provided each time a ground signal is received from the message center. A one-second tone will sound for warning indications from the message center. A 100 milli-second tone will sound for each message center button depressed.
------------------------------------------------------------------------

1. NOTE: The generic electronic module (GEM)/central timer module (CTM) must be reconfigured upon replacement. Refer to the New Generation STAR (NGS) Tester help screen on the configuration card to program the Tire Size, Axle Ratio.
   The power windows system and rear window defroster system are (GEM) controlled systems.

• All Windows Operate With the Ignition in the OFF Position

• Circuitry.
• Accessory delay relay.

• CHECK the accessory delay relay; REFER to Component Test. If OK, REPAIR circuit 400 (LB/BK). If not OK, REPLACE the accessory delay relay. TEST the system for normal operation.

Section 13-09: Gauges, Warning Devices — Chime System 1996 Windstar Workshop Manual
DESCRIPTION AND OPERATION Warning Chime Systems Three distinct sounds are used to indicate the area of concern. Seat belt warning generates 1 chime per second
key-in-ignition generates 2 chimes per second
headlight on generates 4 chimes per second.
Key-In-Ignition Warning The key-in-ignition warning will sound when the driver's front door (20125) is opened with the key in the ignition switch. It will continue to sound until the key is removed, the front door is closed, the ignition switch is turned to START or the vehicle speed is over 24 kmh (15 mph).

Safety Belt Warning When the ignition switch is turned to RUN or START from OFF or ACC, the chime will sound for six seconds or until the safety belt is buckled.

• The safety belt warning indicator lamp (10C859) will activate for 60 seconds or until the driver's safety belt is fastened. Both the chime and lamp activate at the same time.

Anytime the ignition switch is released from START and returns to RUN while the safety belt lamp or chime is activated, the safety belt warning lamp or chime will remain activated until either the timing sequence has been executed, or the safety belt is buckled.

Headlamp Switch On Warning The chime will be activated if the headlamps or parking lamps are ON, the key is not in the ignition and the driver's door is opened. The chime will sound at a rate of four per second.

The key switch usually breaks or wears out and makes contact. It is on the lock cylinder. This would cause the chime to not come on, or stay on. Sounds like the switch is bad.

1997 F-150/250 Warning Chime, Key-In-Ignition The key-in-ignition chime warns that the key is still in the ignition when the driver's door is ajar. The key-in-ignition warning chime will sound when:

• GEM: Driver door is ajar, the ignition switch is in the OFF/LOCK or ACC position and the keys are in the ignition.
• CTM: Driver door is ajar, the ignition switch is in the OFF/LOCK, ACC or RUN position and the keys are in the ignition.

The key-in-ignition warning chime will stop sounding when:

• Driver door is closed.
• Key is removed from the ignition.
• GEM: Ignition switch is switched to the RUN position.

The key-in-ignition warning chime inputs are:

• Ignition switch RUN position (battery potential on both RUN and RUN/ACC inputs).
• Ignition switch ACC position (battery potential on RUN/ACC input only).
• Key-in-ignition switch (grounded with key-in-ignition, open circuit with key-out).
• LH door ajar switch (open circuit with door closed, grounded with door ajar).

This is a pic for a 98, could not find one for 97 which may be the older style which is more prone to break.
