How to do windshield wipers?

Replacing car windshield wipers requires following a standardized process to ensure operational safety and effectiveness, with core steps including preparation, removal of old parts, and installation of new ones. First, turn off the vehicle and activate the wiper maintenance mode (some models require operation after powering on), and place a towel between the wiper arm and the windshield to prevent rebound damage. When removing, lift the wiper arm vertically to 90 degrees, and unlock the buckle according to the interface type (U-type/snap/dovetail): for U-type interfaces, flip open the cover and slide it out; for snap-type interfaces, press the clip and push it out horizontally. Note to mark the original position to avoid reversing left and right. Before installing the new wiper, tear off the rubber strip protective film, align it with the interface direction and insert until a "click" locking sound is heard, and check that the rubber strip fits the glass without warping. After completion, spray windshield washer fluid to test the wiping effect and observe if there are residual water marks or abnormal noises. It is recommended to replace the wipers every 6-12 months. When purchasing, confirm the interface type and size matching the vehicle model (e.g., mainstream Japanese cars commonly use a 28+18-inch combination). In winter, cold-resistant rubber strips can be selected to improve performance. Regularly cleaning sand and dust from the rubber strips and avoiding exposure to direct sunlight can extend their service life. If there is skipping after installation, check the spring tension of the wiper arm or whether the interface is fully engaged.
