- Ensure the wiper motor is getting power by using a test light or voltmeter to check for voltage at the motor's power connector.
- If there is no power, the problem may be with the wiring, the wiper switch, or the relay.
- If there is power, the motor may be faulty and need to be replaced.
2. Check the wiper transmission:
- The wiper transmission is a series of gears and linkages that connect the wiper motor to the wiper blades.
- If the transmission is damaged, the wipers may not move properly.
- Check for any loose or damaged components and replace them if necessary.
3. Check the wiper blades:
- Ensure the wiper blades are not worn out or damaged.
- If the blades are worn out, they will not be able to clean the windshield properly and should be replaced.
4. Check the wiper fluid:
- Ensure the wiper fluid reservoir is full.
- If the reservoir is empty, the wipers will not be able to clean the windshield properly.
If none of these solutions work, you may need to take your vehicle to a mechanic for further diagnosis and repair.
