Tech Tips

If the pulse sensor built into the front power window regulator motor assembly RH (for LHD) or front power window regulator motor assembly LH (for RHD) 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 power window regulator switch assembly at the auto up position, and opened manually by pushing down the power window regulator switch assembly Click here.
