Need help

the guy before me never took care of the blaze, except for oil changes, my truck is just above 90k miles, i was wondering wat service3 i need to do, or needed to do up to now...

It's all listed for ya.  Also check out this thread I had on 100k mile stuff.  http://www.blazerforum.com/m_124459/mpage_1/key_/tm.htm#124469

Ha!  Yeah, the manual will have it detailed out.  Usually I will take the recommended service intervals and cut them in half for the axles, transfer case, and transmission.
