Custom Puddle Lights Not Working After Car Wash? Here’s Why It Happens

Puddle lights are a feature on some vehicles that illuminate the ground below the vehicle when the doors are unlocked, and they can stop working after a car wash due to water ingress or electrical issues. The problem is often reported on the passenger side mirror or driver side mirror, and it can be frustrating for car owners who rely on these lights for safety and convenience.

In this article, we will explore the causes of malfunction, troubleshooting, and repair options for custom puddle lights that are not working after a car wash. We will also discuss puddle light replacements, maintenance, and prevention to help car owners avoid this issue in the future.

The puddle light is usually located on the side mirror and is a separate component from the mirror itself, but it can be challenging to replace due to its location and the fact that it is often sealed within the mirror housing.

Causes of Malfunction

Mirror housing damage

Water ingress is a common cause of puddle light malfunction, especially after a car wash, as it can seep into the mirror housing and damage the electrical components. The mirror glass or mirror housing can be damaged during the car wash process, which can affect the puddle light’s functionality, and it’s crucial to inspect the mirror and housing for any signs of damage.

The puddle light bulb or LEDs can burn out over time, causing the light to stop working, and it’s essential to check the bulb or LEDs and replace them if necessary. The door panel or mirror housing can be misaligned, causing the puddle light to malfunction, and it’s essential to check the alignment and adjust it if necessary.

Car Wash Electrical Problem

Electrical problems are among the main causes of puddle lights not functioning following a car wash. Sometimes, high-pressure water or steam used during car washes might interfere with electrical connections, resulting in problems. Your puddle lights can be especially sensitive to such problems if they are connected straight to the electrical system of the car. Electrical issues, such as faulty wiring or a blown fuse, can also cause the puddle lights to stop working, and it’s essential to check the wiring and fuses before attempting any repairs.

Faulty Vehicle Lights

A general car light failure can explain your puddle lights not working following a wash. This could involve issues with the lights themselves, wiring, or the fuse. Examining other lights in your car will help identify whether the problem is limited to the puddle lights or part of a more general electrical issue.

LED Puddle Light Issue

Though they can still have problems, LED puddle lights are usually dependable. A problem with the LED itself or its connection can exist if your lights flicker or don't turn on following car washing. Check the lights for any obvious damage or disconnection.

Lights Damaged by Water

Custom puddle lights can raise water damage issues. Poor sealing of the lights lets moisture in and creates electrical issues. Sometimes this could cause internal part corrosion, hence disabling the lights. Should you believe water damage, replacing the impacted lights may be required.

Custom Light Problem Solving

Begin by inspecting the connections at the puddle light fixture to diagnose the problem. Make sure every wire is tight and corrosion-free. Should you have access to the wiring harness of the light, check it for any indications of wear or damage. Should everything seem intact, think about using a multimeter to test the lights for continuity.

Automatic Light Short Circuit

Moisture can cause a short circuit by generating an unintentional electrical route, hence causing a problem. A short circuit could be the cause if your puddle lights are not functioning. Check the wiring for frayed or exposed spots that can cause a short. Should you discover any, you could have to fix or replace the impacted wiring.

Car Door Light Problem

The opening of the automobile door usually turns on puddle lights. Should the door switch or wiring be faulty, the lights could not come on as anticipated. Inspect the door switch for correct operation and make sure the cabling linking the switch to the puddle lights is intact.

Symptoms of Wet Wiring

Wet wiring can show itself in different forms, such as flashing lights, sporadic operation, or total failure to illuminate. Should you believe moisture has penetrated the wire, it is imperative to quickly dry off the impacted regions. A hairdryer set to low can help to remove moisture; however, be careful not to overheat any parts.

Troubleshooting and Repair

To troubleshoot the issue, car owners can start by checking the fuse box and replacing any blown fuses, and then checking the wiring and connections for any signs of damage or corrosion. If the issue persists, it may be necessary to replace the puddle light bulb or LEDs, and car owners can purchase replacement bulbs or LEDs from a reputable supplier.

In some cases, the mirror housing or door panel may need to be removed to access the puddle light, and it’s essential to follow proper instructions and take necessary precautions to avoid damaging the surrounding components.

Car owners can also try cleaning the puddle light and the surrounding area to remove any dirt or debris that may be causing the issue, and then check the puddle light’s functionality. If the issue is still not resolved, it may be necessary to consult a professional mechanic or auto electrician for further assistance.

If it's just the light on your mirror lights or welcome lights that’s malfunctioning (while others like the license plate light work fine), check the insert alignment list for proper bulb seating. Many users report the same issue after a car wash—moisture causing flickering or failure. Before replacing, let the housing air dry for one hour—sometimes that’s all it takes. If the problem persists after a few months, it may be a wiring fault. DIY fixes are at your own risk, especially when aiming for that perfect bright white color.

Maintenance and Prevention

To prevent puddle light malfunction, car owners can take steps to maintain their vehicle’s electrical system and avoid exposing the puddle lights to excessive water or moisture.

Regular cleaning and inspection of the puddle lights and the surrounding area can help prevent dirt and debris from accumulating and causing issues, and car owners can use a soft cloth and mild soap to clean the puddle lights.

Car owners can also consider applying a waterproof coating or sealant to the puddle lights and surrounding area to provide extra protection against the elements, and to check the manufacturer’s recommendations for any specific maintenance or repair procedures.

Additionally, car owners can avoid using high-pressure washes or harsh chemicals when washing their vehicle, as these can damage the puddle lights and surrounding components, and use a gentle car wash soap and avoid spraying water directly into the puddle lights.

By following these tips, car owners can help extend the life of their puddle lights and prevent malfunction.

Protecting the Puddle Lamp
