Yes, a wiper motor can often be repaired instead of replaced, depending on the nature and extent of the problem. Common issues with wiper motors include worn-out brushes, faulty wiring, or a malfunctioning relay. If the problem is due to worn brushes, they can be replaced or cleaned to restore functionality. Faulty wiring can be repaired by checking for loose connections or damaged wires and fixing them accordingly. A malfunctioning relay can be replaced to ensure proper operation. In some cases, the motor may be jammed due to debris or corrosion, which can be cleaned to restore movement. Lubricating moving parts can also help in resolving issues related to stiffness or noise. However, if the motor's internal components, such as the armature or windings, are damaged, repair might be more complex and costly, making replacement a more viable option. Before attempting repairs, it's important to diagnose the issue accurately. This can involve testing the motor with a multimeter to check for electrical continuity and ensuring that the power supply to the motor is functioning correctly. If the motor is beyond repair or if the cost of repair is close to or exceeds the cost of a new motor, replacement might be the better option. Ultimately, whether to repair or replace a wiper motor depends on the specific issue, the cost of parts and labor, and the availability of replacement components. If you're not experienced with automotive repairs, consulting a professional mechanic is advisable to ensure safety and effectiveness.

A wiper motor may stop working due to several reasons: 1. **Electrical Issues**: A blown fuse or a faulty relay can interrupt the power supply to the wiper motor.
