    4. As the window goes down, check that the current flow is approximately 7 amps.
      5. NOTE: The PTC opens about 4 - 90 seconds after the window stops going down, so that check must be made before the PTC operates.
    5. Check that the current increases up to approximately 14.5 amps or more when the window stops going down.

      If the operation is not as specified, replace the master switch.
