I also have 98 neon with "door ajar" light and buzzer staying on but ONLY when all doors are closed. key doesnt evan have to be in ignition! also the dome light works perfect with the door and light switch both. (on when open, off when closed.) alredy checked all rubber and is perfect. didnt start this prob till replaced dash cluster 3rd time. only way to not have buzzer is remove lightbulb from dash. WTF please help... this is the 3rd dash. im sick of neon electrical!!!!!!

check all of the door sensors. (buttons that are pushed in when doors close) they sometimes come loose and need adjusting.. easy fix once you find the bad one.

micro switch on one of the latches has failed

This problem is caused by one of the door ajar sensing switches being defective, it is a common fault in Many Ford cars and light trucks. Each door has a switch and two at the tail gate door. The switches are attached to the side of the door latch and very hard to replace, since you would most likely have to detrim at least two doors to find the bad switch the most prudent thing to do is have the dealer scan the door ajar waring system, the scan will indicate exactly which switch has the problem.

If you are getting a dinging then it is more than likely the drivers door.On my '98 the only door that causes the ding is the drivers door.

take and spray wd40 on the latches and open close the door a few times and that should fix the problem that is what was wrong with mine. That took care of problem if that doesnt fix it the senors need to be replaced in the latch

What happens when you remove both switches, and wires? What happens when you use a jumper wire acros both wires, on both doors?

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.

inside the doors is a Small twist in button switch on the door latch assembly that turns on the doom and key buzzer, they stick and make a poor connection, this causes your problem, i have replaced 100's of them, u will have to detrim the door to get at it. The switch is about $10 and u can get it from most parts stores, here is a picture. remember there is one on each door latch.

Hi, my name is adam. By the way your descrpion says, you are having difficulty with the door ajar. My solution is to take a pink eraser and clean off the sensors on each door. Sometimes road dirt and grime get in there and screw it up. Thank you.

is there any type of check engine light on or any type of warning light is the sound of the bell the same bell sound when you open your door or seatbelt warning
