Seat Motor Test

  1. Disconnect seat motor harness connector. With either seat switch in REAR UP position, use a voltmeter and check voltage at harness connector terminal "B". If battery voltage is present, switch position is okay. If battery voltage is not present, repair open circuit to seat switch.
  2. With either seat switch in REAR DOWN position, measure voltage at harness connector terminal "A". If battery voltage is present, switch position is okay. If battery voltage is not present, repair open circuit to seat switch.
  3. With either seat switch in BACK position, measure voltage at harness connector terminal "C". If battery voltage is present, switch position is okay. If battery voltage is not present, repair open circuit to seat switch.
  4. With either seat switch in FORWARD position, measure voltage at harness connector terminal "D". If battery voltage is present, switch position is okay. If battery voltage is not present, repair open circuit to seat switch.
  5. With either seat switch in FRONT UP position, measure voltage at harness connector terminal "F". If battery voltage is present, switch position is okay. If battery voltage is not present, repair open circuit to seat switch.
  6. With either seat switch in FRONT DOWN position, measure voltage at harness connector terminal "E". If battery voltage is present, switch position is okay. If battery voltage is not present, repair open circuit to seat switch. If all seat switch positions check correctly, replace seat motor assembly.
