Solution

1. Preparation

Gather tools: flathead screwdriver, socket set, vacuum cleaner, HVAC cleaning spray.
Ensure the vehicle is parked on a level surface and engine is off.

2. Cabin Air Filter Replacement

Locate the cabin air filter:
- Open the glove box and remove any contents.
- Disconnect the glove box from the hinges by pushing in the sides and allowing it to drop down.
Remove the old filter:
- Locate the cabin air filter cover, typically a rectangular panel.
- Remove the screws or clips securing the cover and take out the old filter.
Install the new filter:
- Insert the new filter, ensuring the airflow direction matches the indicator on the filter housing.
- Reattach the cover and secure it with screws or clips.
Reassemble the glove box:
- Lift the glove box back into place and secure it.

3. Air Conditioning System Check

Inspect for proper operation:
- Start the engine and set the air conditioning to maximum cool.
- Listen for unusual noises from the compressor and check if cold air is being produced.
Recharge refrigerant if necessary:
- Connect a refrigerant gauge to the low-pressure port.
- If levels are low, add refrigerant according to the manufacturer's specifications.

4. Clean HVAC System

Use HVAC cleaning spray:
- Spray the HVAC cleaning solution into the air intake vents (typically located at the base of the windshield).
- Allow the solution to work for the recommended time as per the product instructions.
Run the fan:
- Turn on the vehicle and set the fan to high for 10-15 minutes to circulate the cleaning solution through the system.
