Problems with the Ajar Door Warning Light

As previously mentioned, if you have your vehicle door open but there are no car light indicators showing that it is open, there is a high possibility that a sensor within the dashboard has failed. By replacing the light, or sensor, your car will once again show the proper warning light. However, if you are driving and your door ajar light remains on, you should come to a complete stop and investigate the problem. In many cases, a constant door ajar light may be a sign that the sensor has failed and is no longer able to actively read the connections. Depending on the vehicle, there may be a problem with the connection between the door and the door latch. Because most cars have metallic characteristics, a link may be established from the entrance to the vehicle’s foundation. This is where a problem may occur if the connection is rusted or painted over, preventing current flow. If this is the case, steel wool may be used to assist remove the surrounding components before turning off the interior vehicle lights.

Causes of a Door Ajar Light

The door ajar light is usually triggered by a faulty door jamb switch. They are usually very simple to locate. Typically, it will resemble the switch shown below. It’s typically just one or two bolts that need to be replaced, and they’re inexpensive.

If the car was recently in an accident (especially a severe one), the door jamb switch may no longer make appropriate contact with the door. If that’s the case, it’ll simply be part of the greater amount of body repair required to get your vehicle back on the road safely.

Why Does Your Door Ajar Light Remain On?

Depending on the make and model of your car, your door ajar light may illuminate for a variety of reasons, including:

  • A power outage in the dome light
  • A short circuit in the anti-theft system
  • A door switch that was stuck in the “open” position
  • Wires that are exposed
  • Any of the door switches has an electrical fault.

Although electrical reasons are the most frequent, mechanical causes may also exist. As a result, if one of these sensors illuminates, it’s a good idea to identify the problem as soon as possible—either on your own or by taking your car to your local auto-repair technician.
