Window Motor Initialization: Notes

NOTE: Initialization is required to learn both the full UP and full DOWN positions and the profile of the glass as it travels through the glass channel. Once initialized, obstacle detection is enabled. This procedure is only required for Navigator (LF and RF) or Expedition (LF only) window motors.

NOTE: The window motor must be initialized whenever: the motor is removed from window regulator drum housing, a new motor is installed, a new window regulator is installed, new window glass is installed, glass top run removal or installation is carried out or when carrying out any operation in which grease or lubricants are applied to the window system. All window components (window glass, window regulator, window motor and glass top run) must be installed and tightened to specification before carrying out this procedure. Refer to the DE-INITIALIZATION PROCEDURE prior to performing the window motor initialization (unless a new motor is being installed).

NOTE: A new (or de-initialized) LF/RF (Navigator) or LF (Expedition) window motor will not operate in one-touch up mode until initialized. If a new LF/RF window motor has been installed, proceed to the WINDOW MOTOR INITIALIZATION procedure.

NOTE: Excessive bounce-back (window reverses direction with no obstructions present) may indicate that a de-initialization procedure may need to be performed.
