WARNING: This page is about a different car, the 2015 Chevrolet Spark. However, it is still accessible from the selected car via links, so may be relevant.

Ignition OFF and all vehicle systems OFF, disconnect the harness connector at the S82 Windshield Wiper/Washer Switch. It may take up to 11 min for all vehicle systems to power down.
Test for less than 10 Ω between the low reference circuit terminal 2 and ground.
- If 10 Ω or greater
1. Ignition OFF.
2. Test for less than 2 Ω in the low reference circuit end to end.
  - If 2 Ω or greater, repair the open/high resistance in the circuit.
  - If less than 2 Ω, replace the K9 Body Control Module.
- If less than 10 Ω
Ignition ON.
Test for greater than 8 V between the signal circuit terminal 4 and ground.
- If less than 8 V
1. Ignition OFF, disconnect the harness connector at the K9 Body Control Module.
2. Test for infinite resistance between the signal circuit and ground
  - If less than infinite resistance, repair the short to ground on the circuit.
  - If infinite resistance
3. Test for less than 2 Ω in the signal circuit end to end.
  - If 2 Ω or greater, repair the open/high resistance in the circuit.
  - If less than 2 Ω, replace the K9 Body Control Module.
- If 8 V or greater
Ignition OFF, disconnect the X2 harness connector at the K9 Body Control Module, ignition ON.
Test for less than 1 V between the S82 Windshield Wiper/Washer Switch signal circuit terminal 4 and ground.
- If 1 V or greater
  Repair the short to voltage on the circuit.
- If less than 1 V
Test or replace the S82 Windshield Wiper/Washer Switch.
