  1. Ignition OFF, disconnect the X1 harness connector at the multifunction switch.
  2. Test for less than 20 Ω between the low reference circuit terminal 7 and ground.
    • If greater than the specified range, test the ground circuit for an open/high resistance.
  3. Ignition ON, verify the scan tool Windshield Washer Switch parameter is Inactive.
    • If not the specified value, test the control circuit terminal 6 (with WA9) or terminal 8 (without WA9) for a short to B+. If the circuit tests normal, replace the BCM.
  4. Install a 3 A fused jumper wire between the control circuit terminal 6 (with WA9) or terminal 8 (without WA9) and B+. Verify the scan tool Windshield Washer Switch parameter is Active.
    • If not the specified value, test the control circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the BCM.
  5. If all circuits test normal, test or replace the multifunction switch.
