Fig. Typical trunk lid retaining bolt locations


NOTE
It is good practice, when removing body panels, to apply tape to the corners of the panel and/or cover the adjacent surfaces to help prevent paint damage.

  1. Open the trunk lid (GM calls it the Rear Compartment Lid).
  2.  
  3. Place protective coverings over adjacent body panels.
  4.  
  5. Detach all electrical connectors, as required.
  6.  
  7. If the same trunk lid is to be reinstalled, mark the upper trunk lid hinge location to the lid with a grease pencil.
  8.  
  9. With an assistant, remove the bolts from the upper trunk lid hinge.
  10.  
  11. With an assistant, remove the trunk lid from the vehicle.
  12.  
  13. If the spoiler (if equipped) is to be replaced, remove the nuts from the spoiler mounting studs and lift the spoiler from the trunk lid.
  14.  
  15. Installation is the reverse of the removal process. With an assistant, place the trunk lid on the vehicle and align the lid hinges with the marks made at removal. Tighten the hinge bolts to 18 ft. lbs. (25 Nm).
  16.  
  17. Connect all electrical harnesses and make sure all the body side weather-stripping is in place.
  18.  
  19. Remove the protective coverings and close the trunk lid.

If your windshield, or other fixed window, is cracked or chipped, you may decide to replace it with a new one yourself. However, there are two main reasons why replacement windshields and other window glass should be installed only by a professional automotive glass technician: safety and cost.

The most important reason a professional should install automotive glass is for safety. The glass in the vehicle, especially the windshield, is designed with safety in mind in case of a collision. The windshield is specially manufactured from two panes of specially-tempered glass with a thin layer of transparent plastic between them. This construction allows the glass to "give" in the event that a part of your body hits the windshield during the collision, and prevents the glass from shattering, which could cause lacerations, blinding and other harm to passengers of the vehicle. The other fixed windows are designed to be tempered so that if they break during a collision, they shatter in such a way that there are no large pointed glass pieces. The professional automotive glass technician knows how to install the glass in a vehicle so that it will function optimally during a collision. Without the proper experience, knowledge and tools, installing a piece of automotive glass yourself could lead to additional harm if an accident should ever occur.

Another major consideration is that fixed glass, especially the windshield on late model vehicles, is actually designed to be a structural part of the vehicle. The glass is installed to the vehicle with a very strong adhesive, unlike older vehicles where the glass simply floated in a heavy rubber sealing gasket. On late model vehicles, when the glass is bonded to the metal, the glass actually takes up some of the structural loads imposed on the body. If the glass isn't installed and bonded properly, body strength of the vehicle may be compromised to some degree.

Cost is also a factor when deciding to install automotive glass yourself. Performing this could cost you much more than a professional may charge for the same job. Since the windshield is designed to break under stress, an often life saving characteristic, windshields tend to break VERY easily when an inexperienced person attempts to install one. Do-it-yourselfers buying two, three or even four windshields from a salvage yard because they have broken them during installation are common stories. Also, since the automotive glass is designed to prevent the outside elements from entering your vehicle, improper installation can lead to water and air leaks. Annoying whining noises at highway speeds from air leaks or inside body panel rusting from water leaks can add to your stress level and subtract from your wallet. After buying two or three windshields, installing them and ending up with a leak that produces a noise while driving and water damage during rainstorms, the cost of having a professional do it correctly the first time may be much more alluring. We here at Chilton, therefore, advise that you have a professional automotive glass technician service any broken glass on your vehicle.

GM also cautions that on W-Body vehicles, broken glass might fall into the defroster outlets where it can be blown into the passenger compartment, causing injury. Remind the glass shop replacing a broken windshield to cover the defroster outlets before replacing broken glass.
