Why Volkswagen Interior Lights Wont Turn Off

The door actuator is responsible for opening and closing the doors. If the actuator is not working properly, it may not be able to fully close the door, which can prevent the interior lights from turning off.

Interior Light Switch

The interior light switch is located on the dashboard and is used to turn on and off the interior lights. If the switch is faulty, it may not be able to turn off the lights.

Wiring

The wiring for the interior lights can be damaged or corroded, which can prevent the lights from turning off.

Body Control Module BCM

The BCM is responsible for controlling the interior lights. If the BCM is faulty, it may not be able to turn off the lights.

How to Troubleshoot: Volkswagen Interior Lights Won’t Turn Off

Your Volkswagen’s interior lights are an important safety feature, providing illumination when you need it most. But what happens when the lights refuse to turn off? This can be a frustrating problem, but it’s one that you can usually troubleshoot and fix yourself.

In this guide, we’ll walk you through the steps of troubleshooting a Volkswagen interior lights problem. We’ll cover everything from checking the fuses to replacing the light switch. By the end of this guide, you’ll be able to get your interior lights back on and working properly.

Step 1: Check the fuses

The first step in troubleshooting any electrical problem is to check the fuses. The fuses for your Volkswagen’s interior lights are located in the fuse box. The fuse box is typically located under the dashboard or in the glove compartment.

To check the fuses, you’ll need to find the fuse box and locate the fuses for the interior lights. The fuses are usually labeled, so you should be able to easily identify the ones you need to check.

Once you’ve located the fuses, use a fuse tester to check their condition. If a fuse is blown, it will be blackened or cracked. If you find a blown fuse, replace it with a new one that has the same amperage rating.

Step 2: Check the light switch

If the fuses are good, the next step is to check the light switch. The light switch is located on the dashboard and is usually marked with a light bulb icon.

To check the light switch, turn the ignition switch to the On position and press the light switch. If the interior lights come on, the light switch is working properly. If the interior lights don’t come on, the light switch may be faulty.

To test the light switch, you can use a multimeter to check for continuity. If there is no continuity, the light switch will need to be replaced.

Step 3: Check the wiring

If the fuses and light switch are good, the next step is to check the wiring. The wiring for the interior lights is located in the headliner and the door panels.

To check the wiring, you’ll need to remove the headliner and the door panels. Once you have access to the wiring, use a multimeter to check for any broken or damaged wires. If you find any damaged wires, they will need to be repaired or replaced.

Step 4: Replace the light bulbs

If you’ve checked the fuses, light switch, and wiring and the interior lights still won’t turn off, the problem may be with the light bulbs themselves.

To check the light bulbs, you’ll need to remove them from the housings. Once you have the light bulbs out, you can inspect them for damage. If the light bulbs are burned out or damaged, they will need to be replaced.

Conclusion

Troubleshooting a Volkswagen interior lights problem can be a bit of a challenge, but it’s usually something that you can do yourself. By following the steps in this guide, you should be able to get your interior lights back on and working properly in no time.
