1. Faulty 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 loose, it can cause the wipers to come disconnected or move erratically. Check for any visible damage to the linkage and make sure all the joints are tight.
2. Worn out Wiper Motor: The wiper motor is responsible for driving the wiper linkage. If the motor is worn out or has a problem, it may not be providing enough power to move the wipers properly, causing them to disconnect. Check the motor's electrical connections to ensure they're secure. You may need to replace the wiper motor if it is no longer working.
3. Damaged Spline or Wiper Blade Connection: The wiper blades are attached to the wiper arms through splines or clips. If the splines are worn out or the clips are damaged, it can cause the wiper blades to come loose and disconnect from the wiper arms. Inspect the splines and clips and replace any that are damaged.
4. Faulty Control Switch: The wiper switch controls the operation of the wipers. If the switch is faulty, it might not be providing power to the wiper motor, causing the wipers to stop working or disconnect. Check the switch for any damage and replace it if necessary.
5. Wiring Issues: There might be a problem with the wiring connected to the wiper motor or wiper switch. Check the wiring for any damage, loose connections, or corrosion. Repair the wiring as needed.
If you're uncomfortable troubleshooting these issues yourself, it's best to have your car inspected by a professional mechanic to identify the exact cause and have it repaired accordingly.
