Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle in a safe area, preferably inside a garage or a protected location.

2. Inspect and Replace Wiper Blades

Remove the existing wiper blades by lifting the wiper arm and pressing the release tab.
Install new wiper blades suitable for the Honda Accord Eleventh Generation.
Ensure the blades are securely attached and positioned correctly.

3. Check and Clean the Cabin Air Filter

Locate the cabin air filter housing, usually found behind the glove compartment.
Remove the glove compartment to access the filter.
Take out the old cabin air filter and inspect it for dirt or blockages.
Clean the housing area and install a new filter if necessary.

4. Evaluate and Repair Windshield Seal

Inspect the windshield seal for any gaps or damage.
If damaged, carefully remove the old sealant and clean the area.
Apply new automotive-grade sealant to ensure a proper seal.

5. Test Defrost System

Start the vehicle and set the climate control to defrost mode.
Ensure that the vents are clear and blowing warm air towards the windshield.
If airflow is inadequate, check for obstructions in the vents or consider servicing the HVAC system.
