ADJUSTING METHOD FOR JAM PROTECTION
Note. Use this procedure when power window motor has been replaced, when separating window regulator from power window motor or when operating window regulator with door glass removed.
To adjust limit switch to OFF position, connect motor to harness connector and operate power window motor in UP direction for 4-5 seconds. This sets limit switch to full UP position (OFF).
