Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and turned off.
Wear safety goggles and gloves for protection.

2. Remove Headlight Assembly

Tools Required: Socket set, Torx driver, trim removal tool.
Locate and remove the screws/bolts securing the headlight assembly (typically found in the engine bay).
Use a trim removal tool to gently detach any clips or fasteners holding the assembly.
Carefully pull the headlight assembly away from the vehicle, taking care not to damage wiring.

3. Dry the Headlight Assembly

Use a hairdryer or heat gun on a low setting to evaporate moisture inside the headlight. Keep it at a safe distance to prevent melting plastic.
Alternatively, place the headlight assembly in a warm, dry area for several hours to allow moisture to evaporate naturally.

4. Inspect and Replace Seals

Inspect the rubber gaskets/seals surrounding the headlight for wear or damage.
If damaged, replace them with new ones. Ensure they fit snugly to prevent future moisture ingress.

5. Reassemble Headlight Assembly

Reinstall the headlight bulb and secure it properly.
Reattach the headlight assembly to the vehicle, ensuring all clips and screws are fastened correctly.
Reconnect any wiring harnesses that were disconnected.
