- Fused ignition switch output run/acc circuit open
- Fused ignition switch output circuit shorted to ground
- Fused ignition switch output run/acc circuit shorted to ground
- Common circuit shorted to ground
- High speed output shorted to ground
- Low speed output shorted to ground
- Wiper on/off relay control circuit open
- Wiper on/off relay control circuit shorted to ground
- BCM defective - wiper on/off relay circuit shorted low/open
