What it does
- Drives the wiper linkage
- Provides intermittent, low and high speeds
- Park position returns blades to rest
When it fails
- Wipers do not move
- Only one speed works
- Wipers stop mid-windshield
- Clicking but no movement
How to diagnose
- Check the fuse and relay
- Test the motor with direct power
- Inspect the linkage for seized joints
- Check the switch and wiper control
Maintenance
- Lubricate linkage joints
- Replace worn blades, not just the motor
Use the diagnosis order. When a part fails, confirm each hypothesis with measurements before replacing anything — codes and symptoms overlap.
