Sometimes flipping through a paper manual for no real reason -- and reading whatever catches my eye -- can make for an enjoyable evening
FSM for my (now good) 2004 Envoy is three telephone-book-like volumes compared to two volumes for the Cutlass Supreme (Fisher Body Manual + Factory Service Manual). I suspect the "1 volume difference" is more-detailed safety instructions and more troubleshooting procedures for electronics.
When I'm planning work on either the Mustang or the Cutlass Supreme, as the manuals make you jump between different sections for one specific task -- such as for the Cutlass Supreme, removing/reinstalling the gauge cluster uses 5 different sections in different spots of the manual -- I'll make copies of those pages, mark them up with notes for "where do I go next?", makes notes as I go through the steps, and afterwards will scan to PDF the process I used so I have it if needed in the future; anyone else do this?
