Seat Adjuster Motor Control 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 A and terminal B
    • Seat front vertical motor terminal C and terminal D
    • Seat rear vertical motor terminal E and terminal F
  3. Ignition ON, operate the appropriate seat switch in both directions. The test lamp should turn ON when commanding the motor in both directions.
    • If the test lamp remains OFF during 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.
