If you don't have one already, I highly suggest picking up a Haynes manual, they come in handy sometimes for looking at things like this...

I can't remember if mine has it or not, but on the front of the truck, when you open the hood, on top the rad/fan shroud, there's a few stickers, I think there should be a vacuum diagram somewhere... if it hasn't been rubbed off, lol

 

thanks guys...ill check for the stickers

 

buuuuuuuuuuuuump! still no worky 4x4

 

Are all the vacuum hoses in good shape and connected?

 

My 4x4 went out of mine, a couple of weeks ago. It was a vacuum line that came loose.......it plugged into the back side of the intake manifold. Easy fix(lucky for me!).

 

I dont know what im looking for this is the 1st time I've ever dealt with a 4x4 problem.

We really need a 4x4 section.......would especially help 'noobs' like me, since alot of ppl come on here never previously owning something with 4 wheel drive.

 

Lol, I know that feeling, basically, from what I've seen reading around here in random posts, check round the passenger side of the truck, under the battery, for a bunch of little rubber hoses, and make sure none have come unplugged... It could be the snow pushed some out... I'll try and snap a pic for ya while I'm out there today, if I can find it, lol

 

Here is a picture of the front differential vacuum actuator diaphram:

The diagrams that 20blazer posted are located in the same place?
