Query: Generalities not Specifics

The book takes a lot of space to describe what a relay is, but not where the relays are or what they do on this model car. The book has many sections similar to this, almost like a cut and paste exercise. Generic pictures of tire wear, spark plug condition - who cares? Reference is made to the low pressure switch on the air conditioning circuit - why not show you where it is. Wiring diagrams look like bad photocopies. Pictures of the engine compartment are reversed. Antifreeze colors have changed over the years! I would estimate that only 10 to 15% of the content has to do with the minivan model purportedly covered, the rest is auto "filler" - all in all, a pretty worthless book.
