Good Afternoon!

regarding your door adjar light....

it is not possible to disable the system as it is integral to the GEM module. this module controls several other features of your vehicle, therefore can not be disconnected. The lights typically come on as a result of a sticky switch for the lights. these switches are located on the back side of the door latches. they are not accesable without taking off the door panels. However, i have had success with lubricating the latches and working doors open and closed several times. If you look at the latch on the door itself, you will notice gaps near the corners, spray very generously, penetrating oil or WD40. take into consideration that gravity will pull the oils down, so spray up intop the little openings arround the latch, you are trying to get oil to reach the backside of the latch where the switch is located. do this to all 4 doors and you will more than likely succeed! the only other way to determine wich dor certainly is causing lights to come on is to see your local Ford dealer. only their computers are able to communicate with your onboard computer system to monitor which door is commanding the lamp on. I wish you luck!

ps...your 4 thumbs up is appreciated if i helped you

Driver side door ajar light comes on 2006 chryler 300 c


alarm will obviously sound because the anti theft device thinks door is open...maybe it doesn't think ...it mis detects
check the door light switch and how it is affected by closing opening of door. look at what happens at the contact point.
It may be something mechanical, or something electronic/electrical
empirical testing should reveal the answer

How do you disable the door chime?


many drivers have dash lights to inform them that a door is open yet they still drive around and then complain about a knock some where in the back
I would check all the door sensors for adjustment and leave the alarm alone as , as annoying as it might be , it might let you know when a child has opened a door without your knowledge and save a life.

Door alarm comes on while driving.


This is caused by a defective door ajar switch in one of the 4 doors. The switch is located on the back of the door latch mechanism inside the door. The system can be tested to id the defective switch which is far better than just removing all 4 door panels and rear glass channels to access the 4 switches. Each switch is about $15.00 time to remove them about 4-5 hours for all doors to do this the hard way.

2006 BMW X5 Door open message, inside light goes off & on, and the alarm keeps going off


You have a defective door ajar sensor switch. The switch is located on the door latch of each door inside the door. In order to find out which one is the cause of the false warning a trip to the dealer is required so they can scan the systems control module while the warning is on. If you want to guess start by replacing the drivers door switch first.

Hello. I have a 2000 Mitsubishi Montero Sport. The rear door/hatch no longer stays closed tight enough, so the door ajar light flickers on and off. As a result, my alarm goes off at random times. Could...


The better solution is to fix the hatch so it closes tightly. The latch hooks on to an adjustable loop. The hatch closes on to the rubber seal: if this is damaged, fix or replace. There may be some adjustable rubber bump stops as well. Lastly, check that the door ajar sensor is not loose.
