Anything related to the car body from the firewall/dash back will be found in the Fisher Body manual for your model year.
Any electrical items installed during the body build such as power windows or seats will be found in the FB manual.
The FB manual covers all GM models since the bodies are basically the same between makes.

The service manual covers everything else.
