hey ive had a couple of [posts up here i still cant pass the evap test on my k5.. but i was looking at ordering a repair manual online and i dont know what would be the best one for what i need any one have a favorite or most detailed ..websites and suggestions would be REALLLY helpful..i was looking aT THE CHILTONS SITE IM JUST NEW TO THIS AND NEED A LITTLE HELP

 

I just picked up a factory service manual for my '90 Suburban parts truck for $14 delivered on eBay. Wiring diagram for the same truck for $12 delivered. The manuals for my '74 (wiring, unit repair, service, and complete parts illustrations & number) didn't cost me more than $50 combined! There are deals out there for good used factory manuals and nothing beats the factory manuals!

I just did a quick search on eBay for '78 Blazer Manual' and there were no factory service manuals. You could try a year or two in either direction.

 

just get kyle to right a book about blazers and then buy it from him.
