Power Seat Motor Test

NOTE: On LS400, circuit breaker should reset within 90 seconds.
  1. Disconnect power seat motor connector. Apply battery voltage and ground across power seat motor connector terminals. Reverse polarity to move seat in opposite direction. If power seat motor does not operate, replace power seat motor.
  2. If power seat motor operates, move seat fully in one direction until it stops. With seat stopped, keep battery voltage applied to terminals until circuit breaker is heard opening (within 60 seconds). If circuit breaker does not open, replace power seat motor.
  3. If circuit breaker opens, reverse polarity and wait until seat moves in opposite direction. If seat moves in opposite direction (within 60 seconds), power seat motor is okay. If seat does not move in opposite direction (within 60 seconds), replace power seat motor.
