What Are the Indicators of a Failing Windshield Wiper Motor?
A failing windshield wiper motor can significantly impact your driving safety, especially during adverse weather conditions. Common indicators of a malfunctioning wiper motor include wipers that move slowly, don’t move at all, or make unusual noises. Recognizing these symptoms early can prevent more severe issues and ensure your visibility remains clear.
How Can You Identify Symptoms of a Failing Wiper Motor?
1. Wipers Move Slowly or Erratically
One of the first signs of a failing windshield wiper motor is when the wipers move slower than usual or operate in a jerky, erratic manner. This can be caused by wear and tear on the motor components or electrical issues affecting power delivery.
2. Wipers Do Not Move
If your windshield wipers do not move at all when activated, it could indicate a complete motor failure. Before concluding the motor is at fault, check for blown fuses or damaged wiring, as these are also common culprits.
3. Unusual Noises During Operation
Grinding, squeaking, or other unusual noises coming from the wiper mechanism might suggest that the motor is struggling. These noises can result from worn-out motor parts or debris lodged within the motor assembly.
4. Wipers Stop in the Wrong Position
Wipers that stop in incorrect positions on the windshield often signal an issue with the motor or linkage. This problem can be particularly dangerous as it obstructs the driver’s view, requiring immediate attention.
5. Burning Smell
A burning smell emanating from the wiper area can indicate an overheating motor. This is a serious issue that requires prompt inspection to prevent further damage or potential electrical fires.
Practical Examples and Solutions
-
Example 1: If your wipers move erratically, check the motor’s electrical connections for corrosion or looseness. Cleaning and securing these connections might resolve the issue without needing a motor replacement.
-
Example 2: For wipers that stop mid-sweep, inspect the motor linkage for obstructions or damage. Sometimes, debris can block the linkage, which is easily fixed by cleaning the area.
What Are the Costs of Replacing a Windshield Wiper Motor?
Replacing a windshield wiper motor can vary in cost depending on the vehicle make and model, as well as labor charges. Here’s a comparison table for reference:
| Feature | Economy Car | Mid-Range Car | Luxury Car |
|---|---|---|---|
| Motor Price | $50 – $100 | $100 – $200 | $200 – $400 |
| Labor Costs | $50 – $75 | $75 – $150 | $150 – $300 |
| Total Replacement Cost | $100 – $175 | $175 – $350 | $350 – $700 |
How to Extend the Life of Your Wiper Motor
- Regular Maintenance: Clean your wipers and windshield regularly to prevent dirt buildup that can strain the motor.
- Replace Wiper Blades: Change wiper blades every 6-12 months to reduce the load on the motor.
- Avoid Using Wipers on a Dry Windshield: This practice can cause unnecessary friction and stress on the motor.
