Not what you were thinking!

Where is it? 4x4 wouldn't work this morning and of course we have 4" of snow drifted 2' high in places. Traced the problem to a dis connected vacuum hose. Noticed there is no ball on the hood like my 96. looked high and low for a vacuum ball but couldn't find it.

On a 1999 Chevy Blazer S10 4.3L vortec

 

PRetty much one of three places. If it's not on the hood or next to accumulator it's in the driver's side fender

 

If itsin the fender how do I get to it? have to remove the whole fender?

 

There is thread after thread on this forum about the location of the vacuum canister in the fender search and you will find.

 

General rule: Anything located in the fender is accessible by removing the inner fender. That means the wheelwell liner.

Also: As a layman, {hardware & telecom engineer at Lexis/Nexis for 15 years} I've been doing on-line searches since 1979.
The search algorithm on here reminds me of that one, which was indeed a marvel of that age.
