Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is parked on a flat surface.
Disconnect the battery if electrical components need to be removed.

2. Inspect and Replace Door Seals

Tools Required: Socket set, trim removal tool
Carefully remove the trim around the door seals.
Inspect the seals for any damage; replace if necessary.
Apply adhesive if needed and press the new seal into place, ensuring a tight fit.

3. Seal Windshield and Rear Window

Tools Required: Silicone sealant
Inspect the windshield and rear window seals for gaps or cracks.
Clean the area around the seal with alcohol to ensure proper adhesion.
Apply silicone sealant along the edges and smooth it out to create a watertight seal.

4. Clear Sunroof Drain Tubes

Tools Required: Compressed air or flexible wire
Locate sunroof drain tubes, usually found in the corners of the sunroof frame.
Use compressed air or a flexible wire to clear any blockages from the drain tubes.
Ensure the drains are flowing freely by pouring a small amount of water into the sunroof tray.

5. Clean and Replace Cabin Air Filter

Tools Required: Screwdriver, replacement cabin air filter
Locate the cabin air filter housing, typically behind the glove compartment.
Remove the housing cover and take out the old filter.
Clean any debris from the housing and install the new filter, ensuring it is seated properly.

6. Unblock Drainage Holes

Tools Required: Wire or small brush
Inspect the drainage holes located under the vehicle, usually near the firewall.
Use a wire or small brush to clear any debris that may be obstructing the drains.
