Removal Procedure

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.

If necessary, the rear compartment lift window panel may be manually released by pulling on the manual release cables located behind the cargo compartment rear corner trim panels. Access the cables through the slots in the rear corner trim panels.

The procedure for removing the lift window from the lift window panel is found in Stationary Glass.
