Removal Procedure

    WARNING:

    When working with any type of glass or sheet metal with exposed or rough edges, wear approved safety glasses and gloves in order to reduce the chance of personal injury.

    WARNING:

    If a window is cracked but still intact, crisscross the window with masking tape in order to reduce the risk of damage or personal injury.

    CAUTION:

    DO NOT close the lift window panel with the struts attached unless the window is installed and the window adhesive fully cured. The window adds strength and rigidity to the lift window panel. Attempting to close the lift window panel, with the struts installed, without a window or with the window adhesive not fully cured, could cause the panel to crack.

    NOTE:

    Before cutting out a stationary window, apply a double layer of masking tape around the perimeter of the painted surfaces and the interior trim.

  1. Open the liftgate.
  2. Remove the rear liftgate trim finish panel. Refer to Liftgate Trim Finish Panel Replacement .

    Keep the cutting edge of the appropriate tool against the window. There are window locating pins, one in each upper corner of the window. Use care Not to remove or cut them off when removing the window. If the window locator pins are cut, it will be necessary to tape the window in place.

  6. This will allow the auto-adhesive to be separated from the window.
