Removal Procedure
- Disable the supplemental inflatable restraint (SIR) system. Refer to SIR Disabling and Enabling .
- Disconnect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection .
- Remove all related panels and components.
- Repair as much of the damage as possible to factory specifications. Refer to Dimensions - Body .
- Note the location and remove the sealers and anti-corrosion materials from the repair area, as necessary. Refer to Anti-Corrosion Treatment and Repair .
- Drill spot welds and remove the front upper outer rail.
- Cut the panel where sectioning is to be performed.
- Perform additional sectioning procedures. Refer to Structure Identification .
- Locate and drill out all factory welds. Note the number and location of the welds for installations of the service part.
- Remove the damaged windshield pillar section.
Important: Section in specified areas only. Sectioning outside of these areas may compromise the structural integrity of the vehicle. The door frame can be replaced at factory seams, but requires the removal of the windshield and the roof. The sectioning procedures have been developed as a more cost-effective alternative to complete replacement. The specific area to be sectioned is determined by the extent of the damage to the vehicle.
Important: When replacing panels that involve servicing of stationary glass, refer to Adhesive Installation of Stationary Windows before performing any priming or refinishing.
Caution: Foam sound deadeners must be removed from areas within 152.4 mm (6 in) of where flame is to be used for body repairs. When reinstalling foam sound deadeners, avoid inhaling fumes as bodily injury may result.
Important: Do NOT damage any inner panels or reinforcements.
Installation Procedure
- Cut the replacement windshield pillar section in corresponding locations to fit the original panel. The sectioning joint should be trimmed to allow 1½ times the metal thickness at the sectioning joint.
- Create a 50-mm (2-in) backing plate (1) from the unused portion of the service part. Trim the backing plate as necessary to fit behind the sectioning joint where there is no reinforcement.
- Drill 8-mm (5/16-in) plug weld holes along the sectioning cut on the remaining original part. Locate these holes 13 mm (1/2 in) from the edge and spaced 40 mm (1½ in) apart.
- Drill 8-mm (5/16-in) plug weld holes in the service part as necessary in the locations noted from the original panel and along the sectioning cut.
- Prepare all mating surfaces, as necessary.
- Apply GM-approved Weld-Thru Coating or equivalent to all mating surfaces. Refer to Anti-Corrosion Treatment and Repair .
- Fit the backing plate (2) halfway into the sectioning joint, clamp and plug weld to the vehicle.
- Position the service part.
- Plug weld accordingly.
- Stitch weld the sectioning joint.
- Clean and prepare all welded surfaces.
- Install the front upper outer rail.
- Apply the sealers and anti-corrosion materials to the repair area, as necessary. Refer to Anti-Corrosion Treatment and Repair .
- Paint and repair the area. Refer to Basecoat/Clearcoat Paint Systems .
- Install all related panels and components.
- Connect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection .
- Enable the SIR system. Refer to SIR Disabling and Enabling .
Important: If the location of the original plug weld holes can not be determined, space the plug weld holes every 40 mm (1 1/2 in) apart.
Important: To create a solid weld with minimum heat distortion make 25-mm (1-in) stitch welds along the seam with 25-mm (1-in) gaps between. Then go back and complete the stitch weld.
