Gather necessary tools and parts.
Disconnect the vehicle battery to prevent electrical issues.
Allow the vehicle to cool if recently driven.

2. Inspect and Replace Door Seals

Remove any interior trim panels covering the door seals.
Inspect the rubber seals for cracks or deterioration.
If damaged, remove the old seals and install new ones, ensuring a tight fit.
Use adhesive if necessary to secure the new seals.

Open the sunroof fully to access drainage channels.
Use compressed air or a flexible wire to clear any blockages in the drainage tubes.
Test the drainage by pouring a small amount of water into the channels and ensuring it drains properly.

Inspect the windshield seal for gaps or deterioration.
If damaged, carefully remove the old sealant using a razor blade.
Clean the surface thoroughly.
Apply new automotive sealant around the windshield, ensuring a consistent and thorough application.
Allow the sealant to cure according to manufacturer's instructions.

5. Check and Repair HVAC System

Remove the cabin air filter cover and check for water accumulation.
Inspect the HVAC housing for cracks or misalignments.
Clean any debris or blockage in the drainage pan under the HVAC unit.
Replace the cabin air filter if it's wet or damaged.
