Solution

1. Preparation

Gather tools: screwdrivers, a flashlight, and gloves.
Park the vehicle in a well-ventilated area.
Disconnect the battery (if necessary for safety).

2. Replace Cabin Air Filter

Locate the cabin air filter: Usually found behind the glove compartment.
Remove the glove compartment: Open the glove box and unclip the sides to drop it down.
Extract the old cabin air filter: Slide out the filter and inspect it for dirt and odor.
Install new cabin air filter: Insert a new filter, ensuring it is oriented correctly.

3. Clean the A/C Evaporator Core

Access the evaporator core: This may require removing the dashboard or A/C housing (refer to a repair manual for specifics).
Use an A/C cleaner: Spray a microbial cleaner designed for HVAC systems onto the evaporator core.
Let it sit: Allow the cleaner to work according to the product instructions, typically 10-15 minutes.
Reassemble components: Reassemble the dashboard or A/C housing carefully.

4. Clear A/C Drain

Locate the A/C drain tube: Usually found under the vehicle on the passenger side.
Inspect for blockages: Use a flexible cleaning brush or compressed air to clear any debris.
Check for proper drainage: Ensure water flows freely when the A/C is running.
