Subject:
Liftgate or Liftgate Glass Binds, Does Not Open Completely, CHMSL Hits Roof (Remove Material from CHMSL Applique)
Models:
2002-2005 Chevrolet TrailBlazer EXT
2002-2005 GMC Envoy XL
Condition
Some customers may comment that the liftgate or liftgate glass binds when opening or does not open all the way.
Cause
This condition is caused by the Center High Mounted Stop Lamp (CHMSL) applique hitting the roof of the vehicle.
Correction
Verify that the CHMSL applique is not loose or broken off one or more of its mounting points. If the applique is broken, it will be necessary to order a
replacement part.
Important:
^
It should not be necessary to replace the liftgate glass.
^
All measurements and alterations should take place prior to paint finish.
^
It is necessary to install any replacement parts in order to measure to determine if further modification is required.
To achieve the proper clearance, modification to the applique is required using the following procedure:
1.
Measure (with applique installed) the area of interference in order to determine the material to be removed.
^
The top surface (height) of the applique should line up approximately 1 mm (0.039 in) below the top surface of the roof.
^
A gap of 6-8 mm (0.236-0.315 in) should exist between the roof and the applique to allow for adequate clearance while opening the liftgate.
