Wipers Run At High Speed With Switch In Low Speed Position. Wipers Operate In Intermittent Mode, But Each Wipe Is At High Speed.
- Disconnect motor connector.
- Using two jumper wires, connect one between the battery positive jump start terminal and Pin 2 on the wiper motor connector. Connect the second lead between ground and Pin 5 on the wiper motor connector. If motor runs at low speed, go to Step 3. If motor runs at high speed, replace the motor.
- Check for faulty HI-LO wiper relay. Check for crossed wires in harness from HI-LO relay to motor.
- Disconnect C3 bone 12-way connector from the BCM and remove the HI/LO wiper relay.
- Using an ohmmeter, check terminal 12 of the G3 bone 12-way connector for short to ground.
- If continuity to ground is present, repair as necessary. If no continuity to ground, replace the BCM.
