Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Cabin Air Filter

Locate the cabin air filter housing, usually found behind the glove box.
Remove the screws or clips securing the glove box and gently lower it.
Take out the old cabin air filter and inspect it for dirt or contamination.
Insert a new, clean cabin air filter (refer to the owner's manual for the correct part number).
Reassemble the glove box.

3. Check and Replenish Coolant

Locate the coolant reservoir and remove the cap (ensure engine is cool).
Inspect coolant level; if low, add the appropriate mixture of coolant and water (50/50).
Inspect for leaks by checking hoses and connections around the radiator and engine block.
If leaks are found, replace faulty hoses or components as needed.

4. Inspect and Repair Electrical Components

Visually inspect wiring harnesses and connectors for signs of damage or melting.
Repair or replace any damaged wiring.
Check fuses related to the HVAC system for any blown fuses.
Replace any blown fuses, ensuring to use the correct amperage.
