I’ve been searching for a wiring diagram (schematic) in PDF form, for a 1998 Blazer. Any ideas?

But its going to cost you 24.95.

You could just buy the Haynes manual for $20 and then always have the info for something else as well ~~ granted sometimes it's worthless in that book though

Haynes/Chilton are too general and don't show every circuit. I have one, and yup, just about worthless! I have some GM schematics in PDF form and they're great! Thanks for the reply.
