Common Failure Symptoms of Intermittent Wiper Relay
Signs of Intermittent Wiper Relay Failure & Maintenance Guide
Common Signs of Failure:
1. Wipers Won't Change Speeds
If your wipers stay at one speed regardless of the setting, this is often the first sign of a failing relay.
2. Intermittent Setting Doesn't Work
When the intermittent function stops working while other speeds continue to function, the relay is likely failing.
3. Wipers Stop Mid-Cycle
If wipers freeze in the middle of the windshield or stop randomly during operation, the relay might be malfunctioning.
4. Erratic Wiper Operation
Wipers operating at random intervals or speeds, regardless of the selected setting, indicate relay issues.
Maintenance Schedule:
Regular Inspection:
Have the wiper relay checked during routine maintenance, typically every 30,000 miles or 2 years.
Preventative Maintenance:
- Test all wiper speeds quarterly
- Listen for unusual clicking sounds from the relay
- Check operation before rainy seasons
Replacement Schedule:
While there's no standard replacement interval, most relays last 8-10 years under normal conditions. However, replacement is recommended when any symptoms appear.
Note: Regular maintenance can prevent unexpected failures and ensure proper operation during inclement weather conditions.
