Query: This book is informative, but awful

So there is plenty of great information in this book, and I learned a ton from reading it. I like the tech tips and very detailed facts. However this does not make up for how awfully this book is organized. Either someone was paid by the page, or the publisher decided it would be fun to shuffle around everything. Is there a reason why A/C Compressor styles are spread across two chapters, or could they have just gotten their own? Why is Cabin Filter removal arbitrarily stuffed in the middle of the Heating Fixes Chapter? Why must it cycle btween A/C to Heat every chapter, doesn't it make more sense to separate them entirely? I'm usually a very attentive reader, but I keep drifting when the subject matter is all over the place. Fix the structure of this book and it will be great, otherwise, buy a different one.
