Its not uncommon to experience the annoying door ajar light coming on and staying on when youre driving. This is usually caused by a door not closing properly and can be quite a nuisance. Fortunately, there are a few steps you can take to turn off the door ajar light and get back on the road.
The first step is to make sure the door is closed properly. Check the door latch to make sure its fully latched and the door is completely shut. If the door is not completely shut, it wont trigger the switch that turns off the light. Also, make sure the door is not open too wide. If the door is opened too far, it can cause the switch to stay on and the light to remain lit.
If the door is closed properly, the next step is to check the wiring. This is usually located behind the door panel and can be accessed by removing the panel. Look for any loose wires or cracked insulation that may be causing the issue. If the wiring looks okay, then the next step is to check the door ajar switch itself. This is usually located near the latch and can be accessed by taking off the door panel. Check to make sure the switch is working properly and not stuck in the on position. If the switch is stuck in the on position, it can cause the door ajar light to stay on.
If all else fails, the next step is to replace the door ajar switch. This can be done by purchasing a new one from your local auto parts store and replacing the old one. Make sure to follow the instructions on the packaging for proper installation.
Once the switch is replaced, the door ajar light should turn off. If it does not, then there could be a bigger issue with the wiring or the door latch itself. If this is the case, its best to take your car to a qualified mechanic.
The door ajar light is a minor annoyance, but it can be easily fixed if you take the time to diagnose the issue. By following the steps outlined above, you should be able to turn off the door ajar light and get back on the road in no time.
