Circuit/System Testing

WARNING: This page is about a different car, the 2009 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

Seat Adjuster Switch Circuit Test

  1. Ignition OFF, disconnect the harness connector at the seat adjuster switch.
  2. Test for less than 5 Ω between the ground circuit terminal B and ground.
    • If greater than the specified range, test the ground circuit for an open/high resistance.
  3. Ignition ON, verify that a test lamp illuminates between the appropriate B+ circuit terminal E and ground.
    • 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.

Recline Motor Circuit Test

  1. Ignition OFF, disconnect the harness connector at the recline motor.
  2. Connect a test lamp between control circuit terminal 1 and control circuit terminal 2.
  3. Ignition ON, command the recline motor Forward and Rearward using the seat recline switch. The test lamp should turn ON when commanding the forward and rearward states.
    • If the test lamp remains OFF for either of the commands, test the control circuits for a short to ground or an open/high resistance. If the circuits test normal, test or replace the seat adjuster switch.
  4. If all circuits test normal, replace the seat recline motor.

Seat Adjuster Motor Circuit Test

  1. Ignition OFF, disconnect the harness connector at the seat adjuster motor assembly.
  2. Connect a test lamp between the appropriate control circuit terminals listed below:
    • Seat horizontal motor terminal 3 and terminal 4
    • Seat front vertical motor terminal 2 and terminal 5
    • Seat rear vertical motor terminal 1 and terminal 6
  3. Ignition ON, command the appropriate seat motor Up and Down or Forward and Rearward using the seat adjuster switch. The test lamp should turn ON when commanding the up and down or forward and rearward states.
    • If the test lamp remains OFF for either of the commands, test the control circuits for a short to ground or an open/high resistance. If the circuits test normal, test or replace the seat adjuster switch.
  4. If all circuits tests normal, test or replace the appropriate seat motor.
