1. Check the fuse. The first thing to check is the fuse for the window wipers. If the fuse is blown, replace it with a new one of the same amperage.
2. Check the wiper motor. The wiper motor is responsible for driving the wiper blades. If the motor is not working, the wipers will not move. You can check the wiper motor by turning on the wipers and listening for a humming noise. If you don't hear a humming noise, the motor may be faulty and will need to be replaced.
3. Check the wiper linkage. The wiper linkage is a series of arms and joints that connect the wiper motor to the wiper blades. If the linkage is damaged or disconnected, the wipers will not move properly. You can check the wiper linkage by looking under the hood of your car and inspecting the arms and joints.
4. Check the wiper blades. The wiper blades are responsible for wiping the water off of the windshield. If the wiper blades are worn out or damaged, they will not be able to clean the windshield properly. You can check the wiper blades by looking at them and feeling them. If they are cracked, torn, or brittle, they will need to be replaced.
If you have checked all of the above and the window wipers are still not working, you may need to take your car to a mechanic for further diagnosis and repair.
