Inspection Procedure

  1. INSPECT POWER WINDOW REGULATOR SWITCH (FOR GROUND) 
    1. Remove the power window switch (the connector is connected).
    2. Check the continuity between terminal 7 and the body ground.

      Standard resistance: 

      Below 1 Ω 

    NG: REPAIR OR REPLACE HARNESS OR CONNECTOR
