Troubleshooting
Wipers not heating?
Check the Electronic Control Module (ECM). What lights are blinking?
| ECM Light | Meaning | Solution |
|---|---|---|
| Green Solid | Has power and heating correctly | None required |
| Green Flashing | Has power but not cold enough | It will turn on at 39 degrees or lower |
| No Lights | No power | Start engine, check wiring connection confirm volts are 12.8 or higher |
| No Lights & Hot ECM | Possible positive and negative wires crossed | Check wiring/replace Heated Squeegee |
| Single Red Flashing | Open or shorted circuit in the heating element | Check wiring/replace Thermistor |
| Alternating Red Flashing | Open or shorted circuit in the Thermistor | Check wiring |
Why are my wipers streaking?
- Make sure the gray plastic covering is removed.
- Wipe off squeegee with rubbing alcohol and a rag.
- Check squeegee by running your finger along it to feel for defects.
