WARNING: This page is about a different car, the 2010 Saturn Outlook, 2010 GMC Acadia, 2010 Chevrolet Traverse, and 2010 Buick Enclave. However, it is still accessible from the selected car via links, so may be relevant.
  1. Disconnect the harness connector at the seat adjuster switch.
  2. Ignition OFF, test for less than 1 ohm between the ground circuit terminal B and ground.
    • If greater than the specified value, test the ground circuit for an open/high resistance.
  3. Ignition ON, verify that a test lamp illuminates between the B+ circuit listed below and ground.
    • Terminal E (AH5/AAQ)
    • Terminal D (AG1/AG2)
    • If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.
  4. If all circuits test normal, test or replace the seat adjuster switch.
