Dealer-installed GM Accessories include instruction sheets to aid with installation on most GM passenger cars and light-duty trucks. Many GM Accessory installation instructions also are available in the appropriate Service Information by clicking the Accessories Manual link after building the desired vehicle. (Fig. 13)
If the installation instruction sheet cannot be found with the accessory itself, check the appropriate Service Information. The Service Information includes the latest information regarding accessory installation.
Technicians also can contact ParTech with any questions regarding installation and parts. For assistance, call 1-855-GMCARES (855-462-2737), select 2 from the main menu for ParTech, and select 2 from the ParTech menu for accessories.
TIP: Call the Technical Assistance Center for help with diagnosis of GM Accessories that have been previously installed.
