If found, replace the damaged seals with manufacturer-recommended parts.
Use weatherstripping adhesive if applicable to secure seals.

Locate the AC drain tube under the vehicle.
Use compressed air or a flexible cleaning brush to clear any blockage.
Ensure the tube is securely connected and free from kinks.
