Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface with the engine off.
• Disconnect the negative battery terminal to avoid electrical issues.

2. Inspect Seals

• Sub-steps:
  1. Visually inspect the rubber seals around doors and windows for cracks or deformation.
  2. Run your fingers along the seals to feel for gaps.
  3. Replace any damaged seals with new ones to ensure proper sealing.

3. Replace Cabin Air Filter

• Sub-steps:
  1. Locate the cabin air filter compartment (usually behind the glove box).
  2. Remove the glove box to access the filter.
  3. Take out the old filter and clean any debris from the compartment.
  4. Install the new cabin air filter, ensuring the airflow direction matches the markings.

4. Check Air Conditioning System

• Sub-steps:
  1. Start the engine and turn on the air conditioning.
  2. Verify that the system is cooling effectively; check for unusual noises.
  3. If the system is not functioning properly, consider recharging or repairing it.

5. Inspect for Leaks

• Sub-steps:
  1. Check under the dashboard for signs of coolant leaks, which may indicate a faulty heater core.
  2. Inspect the engine bay for any coolant leaks that could enter the cabin.
  3. If leaks are found, replace the affected components and ensure proper sealing.

6. Clear Drainage Channels

• Sub-steps:
  1. Locate the sunroof drains (if equipped) and check for blockages using a flexible wire or compressed air.
  2. Inspect the windshield cowl area for debris that could block water drainage.
  3. Clear any obstructions to allow proper water drainage.
