Solution

1. Preparation

Ensure the vehicle is parked in a safe, dry location.
Gather tools and materials: ice scraper, soft cloth, de-icing solution, and a warm water container (if necessary).
Safety Warning: Turn off the engine and ensure the vehicle is not in gear.

2. Remove Ice Buildup

Using an Ice Scraper:
- Start scraping the ice from the edges of the windshield towards the center.
- Use gentle pressure to avoid damaging the glass.
Using De-Icing Solution:
- Mix a de-icing solution (2 parts rubbing alcohol to 1 part water) in a spray bottle.
- Spray the solution evenly on the icy areas of the windshield.
- Allow it to sit for a few minutes and then scrape the remaining ice.

3. Improve Defrosting Capability

Check Heating System:
- Turn on the vehicle and set the climate control to the defrost setting.
- Adjust the temperature to maximum heat and the fan speed to high.
- Ensure that the air intake is set to fresh air rather than recirculation.

4. Prevent Future Buildup

Apply a Water Repellent:
- Use a commercial windshield water repellent to create a barrier against moisture.
- Follow the product instructions for application.

5. Address Moisture Issues

Check Cabin Air Filter:
- Remove and inspect the cabin air filter; replace if necessary.
- Ensure the filter is clean to allow proper airflow.
