* Wiper motor failure: The wiper motor is responsible for powering the windscreen wipers. If the motor fails, the wipers will not be able to move. You can check the wiper motor by trying to move the wipers manually. If they move freely, then the motor is likely not the problem.
* Wiper linkage failure: The wiper linkage is a series of arms and joints that connect the wiper motor to the wiper blades. If any of the components of the linkage fail, the wipers will not be able to move properly. You can check the wiper linkage by looking for any loose or damaged parts.
* Electrical problems: The windscreen wipers are powered by the electrical system. If there is a problem with the electrical system, such as a blown fuse or a loose wire, the wipers will not be able to function. You can check the electrical system by using a voltmeter to test the power supply to the wiper motor.
If you are not able to identify the cause of the problem, you should take your car to a qualified mechanic for diagnosis and repair.
