Solution

1. Preparation

Gather tools: flathead screwdriver, trim removal tool, silicone sealant, bucket, and a towel.
Park the vehicle on a level surface and ensure the sunroof is closed.

2. Inspect and Clean Drainage System

Sub-step 1: Remove the sunroof trim using a trim removal tool to access drainage channels.
Sub-step 2: Check drainage tubes for blockages. Use compressed air or a flexible wire to clear any debris.
Sub-step 3: Test the drainage by pouring a small amount of water into the sunroof channel and ensuring it flows out of the drain holes.

3. Replace or Repair Seals

Sub-step 1: Inspect the rubber seals around the sunroof. If damaged, carefully remove the old seals using a flathead screwdriver.
Sub-step 2: Clean the surface where the seal sits to ensure proper adhesion for the new seal.
Sub-step 3: Install new rubber sealant or weather stripping, ensuring a tight fit with no gaps.

4. Seal the Sunroof

Sub-step 1: Apply silicone sealant around the perimeter of the sunroof frame where it meets the roof of the vehicle.
