What are the common failure cases of wipers in a 10-year-old Passat?
1 Answers
10-year-old Passat wiper failure cases are as follows: 1. Wiper malfunction: A Volkswagen Passat sedan with approximately 110,000 km mileage, equipped with a 2.0L engine. The owner reported: The wipers only work normally in intermittent mode, while both low and high-speed modes fail to function. During washer fluid spraying, the washer motor operates normally, but the wiper motor remains inoperative. 2. Fault diagnosis: Since the technician hadn't identified the root cause, all wiper-related components remained uninstalled. The wiper motor was separately placed under the windshield, and the wiper switch was detached and hanging below the steering wheel, leaving the vehicle in a visually distressing state. However, this saved time for potential reinstallation. First confirming the fault phenomenon: when pulling up the wiper switch (washer mode), the buzzing sound of the washer pump could be heard, and washer fluid spraying was visible, but the wiper motor showed no movement.
