CHMSL Applique Contacts Roof When Opening Rear Gate, Glass - kw bind break brake broken center endgate GMT370 hatch hinge molding liftgate light rear trim

When servicing the vehicle with the VIN you entered, the following diagnosis might be helpful if the vehicle exhibits the described symptoms.

Some owners of 2002 to 2004 TrailBlazer EXT and Envoy XL models may comment that the liftgate or liftgate glass binds when opening or does not open completely because the Center High Mounted Stop Lamp (CHMSL) appliqué hits the roof of the vehicle. The appliqué may be loose or broken off one or more of its mounting points. This condition will require replacement of the CHMSL applique. During replacement of the appliqué, assure proper alignment of the mounting brackets. This can be accomplished by comparing them to the brackets on a known good vehicle. It should not be necessary to replace the liftgate glass. Once installed, the top surface of the appliqué should line up approximately 1mm below the top surface of the roof. Although the root cause of this concern has not been determined at this time, an engineering study is being conducted. Further information will be provided when it is available.

If these steps do not resolve the condition, please contact GM TAC for further diagnostic assistance.
