Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked in a safe, warm area if possible.
Disconnect the battery if necessary to avoid any electrical issues.

2. Replace Wiper Blades

Remove the old wiper blades by lifting the wiper arm and pressing the release tab.
Slide the old blades off the arm and align the new blades.
Securely attach the new wiper blades, ensuring they click into place.

3. Check and Replace Cabin Air Filter

Locate the cabin air filter, usually accessed from the glove compartment.
Remove the glove compartment and any covers to reach the filter.
Take out the old filter and inspect for dirt or blockages; replace with a new filter if needed.

4. Inspect and Repair Windshield Seal

Visually inspect the windshield seal for cracks or gaps.
If damaged, carefully remove the old sealant using a plastic scraper.
Clean the area and apply a new sealant (automotive-grade silicone or urethane) according to manufacturer instructions.

5. Flush and Check Heating System

Ensure the coolant is topped up in the reservoir.
Start the engine and run the heater on high to check for proper airflow from the vents.
If inadequate heating is observed, consider flushing the heating system and replacing the thermostat if necessary.
