Door open chime

When you open the door down towards the bottom is a black push button when the door is open the chime sounds you can push it in and tape it

Its sensing that there is a key in the ignition. You have to replace the switch in the ignition cylinder that senses a key is inserted. Or alternatively access a wiring diagram and cut the wire from the key sensor to eliminate it.

There is another legitimate and easy way to disable seat belt chime. Radio is supposed to stay on til door opens. That is correct

Key in ignition or the spring in the ignition cylinder that activates chime for "key in ignition and door open" is stuck. Fast chime is lights and slow chime is key in ignition while door open

Sometimes the ignition key does not "deactivate" when removing the key...try wiggling the washer behind where the key goes...sometimes this sticks...:)

The waring chime is located above the fuse box under the dash, open door with the keys in the ignition, let it chime and follow the sound, it will make it easier to find, then unplug it. Hope this helps.

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.

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.

Warning Chime Systems The generic electronic module (GEM) will sound the following warnings:

• key-in-ignition warning
• safety belt warning
• headlamp switch ON warning
• door ajar warning

------------------------------------------------------------------------------------------------
Headlamp Switch On Warning The generic electronic module (GEM) sounds when the driver door is opened while the headlamp switch (11654) is in the PARK or HEAD position, and continues to sound at a rate of 4 chimes per second until the headlamp switch is turned off or the driver door is closed.

• When the headlamp switch is in the PARK or HEAD position, power is supplied through Circuit 293 (O/R) to the GEM.
• When the driver door is open, the driver door open warning lamp switch (10B997)is closed and ground is supplied to the generic electronic module (GEM).

A delayed headlamps on repetitive chime will sound for a period of three seconds beginning twenty seconds after the key is turned to OFF, LOCK or ACC, the headlamp switch is in the PARK or HEAD position, and the driver door is closed. Delayed headlamps on is terminated by opening and closing the driver door again.
---------------------------------------------------------------------------------------
Door/Liftgate Ajar Warning The door/liftgate ajar warning functions as follows:

• The generic electronic module (GEM) sounds a warning tone for one second when any vehicle door, liftgate window or the liftgate is ajar without any other door already open and the ignition switch is in the RUN position.
• Power is then supplied through Circuit 627 (BK/O) to the door ajar warning indicator lamp which remains illuminated until all doors are closed or the ignition switch is no longer in the RUN position.

----------------------------------------------------------------------------------------------
Key-in-Ignition Warning The generic electronic module (GEM) sounds when the LH front door is opened with the key in the ignition switch and continues to sound until the key is removed or the door is closed.

• When the key is in the ignition switch, the ignition key warning switch terminal and wire (11A128) is closed and ground is supplied through Circuit 158 (BK/PK) to the generic electronic module (GEM).
• When the LH front door is open, the LH front door open warning lamp switch (10B997) closes and ground is supplied through Circuit 57 (BK) to the generic electronic module (GEM).

-------------------------------------------------------------------------------------
Safety Belt Warning When the ignition switch is turned to RUN or START from the OFF or ACC position and remains in RUN or START, the chime will sound for six seconds or until the safety belt is buckled. The safety belt warning indicator lamp (10C859) will turn on for 60 seconds, or until the LH front safety belt is fastened. Both the chime and lamp activate at the same time. If the safety belt is buckled when the ignition key is turned to RUN or START from OFF or ACC, the lamp will prove out for two seconds, but chime will not be activated. Any time the key 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.

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.
