How to Solve Frost on Car Windshield in Summer?
1 Answers
This occurs when the cool air from the car's air conditioning lowers the temperature of the windshield, causing the water vapor in the outside air to condense upon contact with the cold surface. It's the same principle as when a chilled drink taken out of the refrigerator in summer has small water droplets on its surface. Here are the solutions for frost on the car windshield: 1. Warm up the car sufficiently: If there is frost on the windshield, do not use the wipers to scrape it off. Instead, properly warm up the car while stationary, wait for the engine coolant temperature to rise, and avoid turning on the heater during this period. 2. Turn on the heater: After starting the vehicle and warming it up, and once the engine coolant temperature has risen, you can turn on the air conditioning heater, select the windshield defrost mode, set the heater to the highest setting, and wait patiently for 5~10 minutes.
