Removal Procedure

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.

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

Remove the rear lift window struts. Refer to STRUT REPLACEMENT - REAR LIFT WINDOW PANEL .
