What are the common reasons why front window wipers stop working?
Many factors can lead to malfunctioning front window wipers. One common issue is a blown fuse, which can prevent the wiper motor from receiving power. Another possible reason is a faulty wiper motor itself, which may wear out or fail over time. Additionally, the linkage between the wiper motor and the wiper blades can break or become disconnected, leading to a complete loss of function.
Weather conditions can also affect wiper performance. For instance, if ice or snow is preventing the wipers from moving, this can strain the motor, leading to burnout or damage. Regular maintenance, like ensuring the wiper blades are free of debris and functioning properly, can also prevent unexpected issues.
How can I check if the wiper motor is functioning?
To check if the wiper motor is functioning, first, turn on the ignition and activate the wiper switch.
