Why Volkswagen Tiguan Interior Lights Wont Turn Off

Door Ajar Switch

The door ajar switch is a safety feature that is designed to keep the interior lights on when a door is open. If the door ajar switch is stuck in the open position, the interior lights will not turn off.

Interior Light Switch

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

Wiring Harness

The wiring harness is a series of wires that connect the interior light switch to the interior lights. If the wiring harness is damaged, it may not be able to send the signal to turn the lights off.

Light Bulbs

The light bulbs in the interior of the Volkswagen Tiguan are designed to last for a long time. However, if a light bulb burns out, it may not be able to turn off.

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

The interior lights in your Volkswagen Tiguan should turn off automatically when you exit the vehicle. However, if they stay on, it can be a nuisance and even a safety hazard. There are a few possible causes for this issue, and you can troubleshoot them yourself using the following steps.

Step 1: Check the door switch

The most common cause of interior lights that won’t turn off is a faulty door switch. To check this, open and close each door of the vehicle. If the lights stay on when you close a door, the door switch is likely the culprit.

To fix this issue, you will need to replace the door switch. This is a relatively simple task that can be completed in about 30 minutes. You can find replacement door switches at most auto parts stores.

Step 2: Check the interior light fuse

Another possible cause of interior lights that won’t turn off is a blown fuse. To check this, locate the interior light fuse in the fuse box. The fuse box is typically located under the hood of the vehicle.

Once you have located the fuse, remove it and inspect it for damage. If the fuse is blown, it will be blackened or cracked. If the fuse is blown, you will need to replace it with a new fuse of the same amperage.

Step 3: Check the wiring

If the door switch and fuse are both good, the next step is to check the wiring. The wiring for the interior lights runs through the doorjambs. To check the wiring, you will need to remove the door panels.

Once you have removed the door panels, you can inspect the wiring for damage. Look for frayed wires, broken wires, or wires that are disconnected. If you find any damage, you will need to repair or replace the wiring.

Step 4: Take your vehicle to a mechanic

If you have tried all of the above steps and the interior lights still won’t turn off, it is time to take your vehicle to a mechanic. A mechanic will be able to diagnose the issue and make the necessary repairs.

Conclusion

Interior lights that won’t turn off can be a nuisance, but they can also be a safety hazard. By following these steps, you can troubleshoot the issue and get your interior lights working properly again.
