Windshield Wiper/Washer Switch Circuit Test

WARNING: This page is about a different car, the 2010 Cadillac SRX. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition OFF, disconnect the X1 harness connector at the S82 windshield wiper/washer switch.
  2. Verify a test lamp illuminates between the low reference circuit terminal 2 and B+.
    • If the test lamp does not illuminate, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the K9 BCM.
  3. Ignition ON, test for B+ between the signal cirucit terminal 1 and ground.
    • If less than the specified value, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the K9 BCM.
  4. Ignition ON, test for B+ between the signal cirucit terminal 3 and ground.
    • If less than the specified value, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the K9 BCM.
  5. Ignition On, test for 10 V between the signal circuit terminal 5 and ground.
    • If less than the specified value, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the K9 BCM.
    • If greater than the specified value, test the signal circuit for a short to voltage. If the circuit tests normal, replace the K9 BCM.
  6. If all circuits test normal, test or replace the S82 windshield wiper/washer switch.
