The door-open light staying on is a common problem that happens when the door switch plunger sticks (most likely due to an accumulation of dirt or rust). Fortunately, this is a simple problem to fix and doesn’t take a lot of automotive expertise to repair. Read more to learn what to do if your car door open light stays on.
You’ll first want to thoroughly clean the door switches on all the doors with a cleaning spray. This should at the very least loosen up any of the accumulated grime that’s built up within the door switch. You should then use compressed air to clear all the dirt and grime from those switches, and then apply a spray lubricant to the switches. You then want to lubricate the surface of the switches, which can done with either a dry lubricant or the more commonly found WD-40. Try to avoid having too much excess lubricant on the switches, as the lubricant may leak into your car or damage other parts in the general area.
If this doesn’t work, you can also take the door panel and do the same treatment from the other side of the door switch to ensure the door switch is completely cleaned and lubricated all around. However, if the door switch light is still on after the entire treatment, there may be some faulty wiring or the switch may need to come out for repair. It’s highly suggested that you leave this job to an auto-repair professional, since they will have the necessary tools and expertise to properly repair your car. Likewise, if you ever feel uncomfortable or unsure during the process of cleaning your door switches, you may just want to have your car looked at a mechanics.
