Windshield wipers can leave permanent marks on the windshield if they are not maintained properly or if debris gets caught between the wiper blade and the glass. Over time, the constant friction of the wiper blades against the glass can cause scratches and streaks that may be difficult to remove. It's important to regularly clean and replace the wiper blades to prevent any permanent damage to the windshield. **

It is possible that the windshield wiper is broken because of the frozen windshield. When the windshield is frozen, the wiper blades can become stuck to the glass, and attempting to use them can cause damage to the wiper motor or the blades themselves. Additionally, the strain of trying to move the wipers over a frozen windshield can also cause damage to the wiper system. It is important to properly defrost the windshield before attempting to use the wipers to prevent damage. **

Yes, using windshield wipers on a dry windshield can cause damage to both the wipers and the windshield. When the wipers move across a dry surface, they can become worn down and develop cracks, reducing their effectiveness in clearing water when it does rain. Additionally, the dry friction between the wipers and the windshield can cause scratches and damage to the glass. It's best to only use windshield wipers when there is moisture on the windshield to avoid unnecessary wear and tear. **

Your windshield wiper may be raised up either intentionally or accidentally. Intentionally, it could be to make it easier to clean or replace the wiper blade. Accidentally, it could be due to a malfunction in the wiper arm mechanism or if someone manually lifted it and forgot to put it back down. It's important to ensure that the wiper is properly positioned to ensure optimal performance when in use. **

To remove snow from the windshield using the windshield wipers, first turn on the car and activate the windshield wipers. Then, use a snow brush or scraper to remove as much snow as possible from the windshield. As the wipers move back and forth, they will help to clear any remaining snow or ice from the windshield. It's important to make sure the wipers are not frozen to the windshield before turning them on, as this could damage the wiper blades or motor. **

The windshield can fog up from the outside due to a difference in temperature between the inside and outside of the car. When the outside temperature is cooler than the inside temperature, moisture in the air can condense on the exterior surface of the windshield, creating fog. This can happen in humid conditions or when the car has been parked in a colder environment and then brought into a warmer one. Using the windshield defroster or air conditioning can help clear the fog by adjusting the temperature and humidity levels inside the car. **

Your windshield may be fogging up on the inside due to a difference in temperature and humidity between the inside and outside of your car. When warm, moist air comes into contact with the cooler surface of the windshield, it can condense and form fog. This can be exacerbated by factors such as wet clothing or shoes, or a malfunctioning HVAC system that is not effectively removing moisture from the air inside the car. To prevent fogging, try using your car's defroster, adjusting the temperature and humidity levels inside the car, and ensuring good air circulation. **

The windshield fogs up when warm, moist air comes into contact with the cooler surface of the glass. This causes condensation to form, creating the foggy effect. If the interior of the car is also humid, the fog may not improve because the moisture continues to be present in the air, perpetuating the condensation on the windshield. Additionally, if the car's ventilation system is not effectively removing the moist air from the interior, the fog may persist. **
