WARNING: This page is about a different car, the 2008 Buick Lucerne. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition OFF, disconnect the X2 harness connector at the driver outside rearview mirror.
  2. Ignition OFF, test for less than 1.0 ohm between the low reference circuit terminal 1 and ground.
    • If greater than the specified range, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the driver door module
  3. Ignition ON, command the left side blind zone indicator ON with the scan tool. Test for greater than 2.5 volts between the control circuit terminal 4 and ground.
    • If less than the specified range, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the driver door module.
  4. If all circuits test normal, replace the driver outside rearview mirror.
