1. Obstruction: Check if there's any obstruction, like leaves or debris, preventing the wiper from fully retracting. Ensure the wiper path is clear and free from any obstacles.
2. Wiper Arm Misalignment: The wiper arm may have become misaligned, causing the wiper to stop halfway. Inspect the wiper arm for any bending, twisting, or misalignment. It may need to be adjusted or replaced if necessary.
3. Worn Wiper Motor: If the wiper motor is worn out or malfunctioning, it can affect the wiper's movement. Listen for any unusual noises during wiper operation. A faulty wiper motor may need replacement.
4. Faulty Linkage: The linkage system connects the wiper motor to the wiper arm. Check the linkage for any looseness, damage, or disconnected components. Tighten any loose connections or replace damaged parts.
5. Faulty Wiper Transmission: The wiper transmission transfers power from the wiper motor to the wiper arms. If the transmission is faulty, it can cause irregular wiper movement or prevent them from fully retracting. Inspect the transmission and have it repaired or replaced if needed.
6. Electrical Issues: Verify that the electrical connections between the wiper switch and the wiper motor are functioning correctly. Check for loose wires or damaged connectors that may interrupt the power supply to the wiper motor.
7. Faulty Wiper Switch: The wiper switch controls the operation of the wipers. If the switch is malfunctioning, it may cause the wipers to stop at the wrong position. Test the wiper switch to determine if it needs to be replaced.
8. Software Issue (if Applicable): Some modern vehicles incorporate software components to control wiper functions. If your car has such a system, consider checking for updates or potential software issues that might be affecting the wiper movement.
If you're unable to identify or fix the cause, it's recommended to take your vehicle to a professional mechanic or auto repair shop for a proper diagnosis and repair, as it may involve specialized tools and expertise to resolve the issue effectively.
