      2. No:  If only the front height adjust motor operates, GO to 5  on page 3.

        If only the rear height adjust motor operates, GO to 7  on page 5.

  5. CHECK FOR VOLTAGE TO THE REAR HEIGHT MOTOR
      WARNING: Turn the ignition OFF and wait one minute to deplete the backup power supply. Failure to follow this instruction may result in serious personal injury or death in the event of an accidental deployment.
    1. Ignition OFF.
    2. Disconnect: Driver Seat Side Air Bag C3051.
    3. Disconnect: Driver Seat Rear Height Motor C363.
      4. NOTE: During the following step, the voltage being measured changes polarity dependent upon which direction the seat control switch is activated.

      1. Yes:  INSTALL a new seat control switch. REFER to SEAT CONTROL SWITCH . GO to 9  on page 7.
      2. No:  REPAIR the affected circuit. GO to 9  on page 7.
  7. CHECK FOR VOLTAGE TO THE DRIVER SEAT FRONT HEIGHT MOTOR
      WARNING: Turn the ignition OFF and wait one minute to deplete the backup power supply. Failure to follow this instruction may result in serious personal injury or death in the event of an accidental deployment.
    1. Ignition OFF.
    2. Disconnect: Driver Seat Side Air Bag C3051.
    3. Disconnect: Driver Seat Front Height Motor C382.
