Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety while working with electrical components.

2. Inspect and Replace Seals

Sub-steps:
1. Remove the sunroof trim by gently prying it off with a trim removal tool.
2. Carefully lift the sunroof panel to access the seals.
3. Inspect the rubber seals for wear, cracks, or detachment.
4. If damaged, remove the old seal using a trim removal tool.
5. Clean the area where the new seal will be applied with a suitable cleaner.
6. Apply a new seal (specific for Honda Civic) and press it firmly into place.

3. Clear Drainage System

Sub-steps:
1. Locate the drainage holes at the corners of the sunroof frame.
2. Pour a small amount of water into the sunroof channel and observe if it drains properly.
3. If drainage is slow or blocked, use compressed air to blow out any debris from the drainage tubes.
4. Verify drainage by pouring water again and ensuring it flows freely out of the vehicle.

4. Reassemble Components

Sub-steps:
1. Reinstall the sunroof panel by aligning it correctly and ensuring it operates smoothly.
