Solution

1. Preparation

  3. Take out the old cabin air filter and inspect for mold or debris.
  4. Clean the compartment with a vacuum cleaner.
  5. Install a new cabin air filter, ensuring it is oriented correctly as per manufacturer markings.

3. Clean Evaporator Core

• Sub-steps:
  1. Access the evaporator core, which may require removing the dashboard or specific panels.
  2. Spray a mold and mildew cleaner onto the evaporator core.
  3. Allow the cleaner to dwell as per the product instructions.

4. Clear AC Drain Tube
