Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to avoid electrical issues during inspection.

2. Inspect and Replace Door Seals

Remove the door panel carefully using a trim removal tool.
Inspect the rubber seals around the door for any signs of wear or tears.
If damaged, remove the old seal and clean the area.
Install a new door seal, ensuring it fits snugly; use adhesive if necessary.
Reattach the door panel and ensure all clips are secured.

3. Clear Sunroof Drains

Open the sunroof fully.
Locate the drain holes at the corners of the sunroof.
Use a flexible wire or a compressed air canister to clear any debris from the drains.
Run water through the drains to ensure they flow freely.

4. Check and Reseal Windshield and Rear Window

Inspect the edges of the windshield and rear window for signs of sealant failure.
If the seal is compromised, carefully cut away the old sealant with a utility knife.
Clean the area thoroughly to remove old adhesive.
Apply a new automotive-grade sealant and smooth it out evenly.
Allow adequate curing time as per the sealant instructions.

5. Inspect Cabin Air Filter Housing

Locate the cabin air filter housing under the dashboard.
Remove the cover and check for any debris or blockage.
Ensure the housing seals properly against the dashboard.
Replace the cabin air filter if it shows signs of moisture damage.
