Passat Wiper Malfunction Light On?
2 Answers
If there is an exclamation mark on the windshield pattern, it indicates the wiper malfunction warning light. When this light is illuminated, it signifies a fault in the wiper system. The appearance of an indicator light with an exclamation mark on the dashboard usually means there is an abnormality or malfunction in the corresponding part. Vehicle owners should not overlook this and should promptly identify the source of the issue to prevent further damage. Wiper maintenance tips: If the wipers have been in use for 1-2 years, it is recommended to replace them promptly. By this time, the wiper rubber strips, after enduring one to two years of exposure to wind and sun, will have started to deteriorate. To determine if the wipers can effectively clear rainwater from the windshield, especially during light rain when the wipers leave the glass blurry after wiping, gently lift the wiper and inspect the rubber strips for cracks or fissures. If cracks or wrinkles are present, replacement is necessary.
The Passat's windshield wiper warning light came on, an issue I've encountered a few times with this car. Generally speaking, when the light illuminates, it mostly indicates a minor problem with the wiper system. It could be that the wiper motor has failed, causing a signal interruption due to inability to operate normally; or there might be an issue with the relay, resulting in malfunctioning control circuitry; a blown fuse is also quite common, as frequent operation during rainy weather can easily cause it to burn out; another possible reason is a sensor fault, where the system can't detect the wiper position and thus lights the warning. For a simple check, you can pop the hood yourself and look for the wiper fuse in the fuse box to see if it needs replacement; if the light remains on after changing it, it's best not to delay and promptly visit a professional repair shop for diagnosis. Safety first—having faulty wipers during heavy rain that can't clear the windshield creates dangerously blurred visibility.
