1998 F-150 Door Ajar Light Problems

I like Ford reliability, but their trucks lack features that make a Working man's day easier. Anytime I roll down my driver side window and hit a few bumps the door ajar light stays on, along with the inside light. I am also SICK of the key buzzer. Any thoughts? I have a 98 f150 and i had the same problem with the door ajar and dome light....tried the wd-40 and that solved the problem. But, the buzzer goes off every time i open the door (even if the lights are off and the key is out of the ignition)..DRIVES ME CRAZY! is there anyway to get the buzzer to go off only if the lights are left on or is it all or nothing?

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.

1999 Ford Explorer,Door ajar light & Chime goes on & off while driving,int lights & auto headlights won't shut off after car off & all doors closed.

Your best bet would be to find a Tech like this guy , with the right diagnostic equiment . Door Locks Go Crazy 1 Unless you know how to do automotive electrical testing . Your door ajar switch is a input to a body control module . or GEM as ford calls thiers .
Door Locks Go Crazy 2 Your auto lights are controlled pretty much the same .
Electric Testing Techniques You Need to Know

Do you know what DTC"S are ? diagnostic trouble codes ! You probably have a door ajar switch problem . You need a factory or professional type scan tool to check these codes

Ford fiesta ajar light stays on and central lock not working

The central locking will not work when a door is open. find the door which is ajar and fix the door switch. Could be a stuck switch (either open or shut) May just need a whack with a soft faced hammer on the door frame. Don't hit it too hard you could dent the panels.

The door ajar beeping comes on anytime a door is open, whether or not a key is in the ignition.

The light and the beeping are two differant things. Headlight switch on? Or the switch were the key gos may think the key is still in the switch.

Ford Taurus SE 1999. Dome Light - Door Ajar indicator problem. This is an intermittent problem, hence far more difficult to isolate. OK. I will be thorough in describing this "set of problems" as I do...

i must say that i feel your pain with this,, my door ajar light does the same thing but my dome light doesn't come on when the doors are open, i have to flick the switch on the dome light to make it come on. In my opion and i stress my opion it saounds like a issue with the body controller, im not sure what ford calls it but it controls all the body functions, i dont think the low coolant light is connected to the body contoller but i dont know this for sure, i think that light is controlled bny the engine ecm. some times a dealer can connect to the body controller and see if there are any fault codes for circuits that it controls and or monitors, also they can reflash or update the configeration and or calibration level cause ford release's fixes for issues all the time, same theory works for any control module on a vehicle. i dont think any of the auto parts stores have the right program to connect to bofy controlers but i could be wrong, worth looking into. i only put up with mine cause i use it as a beater, if you are worried about your dome light staying on and drianing your battery then you could pull out or disconnect the dome lights for the time being, its not a fix but just a band-aid.

My passenger door has no power,my security light is on constantly

Have lost power to the passenger side door. Without power system doesnt recognize door closed because of no power to door ajar switch which keeps dome light on. Security light stays on because without power to rest of systems supplied by fuse it cannot tell if doors and windows closed to engage security features. Most common is for power wire to break somewhere near where it leaves to main body and enters the door.

Door ajar

The switch on the door frame that tells the computer the door is closed is probably broken or has a loose wire. Could be any of the doors.
