Tech Tips

If the pulse sensor built into the rear power window regulator motor assembly RH is malfunctioning, the power window control system enters fail-safe mode. The remote up and down and auto up and down functions cannot be operated during fail-safe mode. However, the power window can be closed by holding the rear power window regulator switch assembly (for rear RH door) at the auto up position, and opened manually by pushing down the rear power window regulator switch assembly (for rear RH door).
