Power Seat Motor Test

WARNING: This page is about a different car, the 1996 Lexus SC 300 and 1995 Lexus SC 300. However, it is still accessible from the selected car via links, so may be relevant.
  1. Disconnect power seat motor connector. Apply battery voltage 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 operating (within 60 seconds). If circuit breaker does not operate, replace power seat motor.
  3. If circuit breaker operates, 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.
