If you’re noticing issues with your windshield wipers, it might be due to a failing windshield wiper motor. Common signs include wipers moving slower than usual, not moving at all, or stopping mid-swipe. Understanding these symptoms can help you diagnose the problem early and take necessary action.
What Are the Symptoms of a Failing Windshield Wiper Motor?
Recognizing the signs of a failing windshield wiper motor is crucial for maintaining clear visibility during adverse weather conditions. Here are some common symptoms to watch for:
- Sluggish Movement: If your wipers are moving slower than usual, it might indicate a failing motor.
- Intermittent Operation: Wipers that work sporadically or stop mid-swipe can be a sign of motor failure.
- No Response: When the wipers do not respond at all, the motor could be completely non-functional.
- Unusual Noises: Grinding or whining sounds when the wipers are in use may suggest motor issues.
- Single Speed Functionality: If the wipers only operate at one speed, it might be due to a faulty motor.
How to Test Your Windshield Wiper Motor?
Testing your windshield wiper motor involves a few simple steps to determine if it’s functioning correctly:
- Check the Fuse: Ensure the wiper fuse is intact. A blown fuse can mimic motor failure symptoms.
- Inspect the Wiper Linkage: Sometimes, the issue might be with the linkage rather than the motor itself.
- Test the Motor: Use a multimeter to check for electrical continuity in the motor. If there’s no power, the motor may need replacement.
- Listen for Sounds: Activate the wipers and listen for any unusual noises from the motor area, indicating potential problems.
