DESCRIPTION

  1. If the AUTO UP/DOWN function does not operate, the cause may be one or more of the following:
  1. The recorded power window fully closed position, which is stored in the multiplex network master switch, was erased as a result of: 1) a fuse or relay related to the driver side power window being replaced; or 2) the battery cable and the master switch's connector being disconnected.
  2. The master switch has a malfunction.
  3. The pulse sensors in the driver side power window regulator motor have a malfunction.
  4. The wiring between the master switch and the driver side power window regulator motor is open or short.
