I have a 2000 2-wheel drive LS S-10 chevy blazer with 4.3L and my question is i have a vacuum hose that i cant find where it goes.Theres a hose that comes from the driverside fender and goes to a T,then the other half of hose was just sitting over the brake booster.I bought the blazer like this and its been bugging me since day one..Ive looked and looked around and cant seem to find where it goes..Hope you guys can help me out..its appericated..Thanx

 

A picture would help, but if its the same vac line that everyone else talks about then it goes to an accumulator inside the driver side fender. Its not easy to get to and with it unplugged your 4WD wont work. It plugs into a plastic nipple right below the right bolt on the abs module (if standing on outside of fender)... You can also take out that bolt and pull up on the abs module to give you a little more space.

 

I had one right there that turned out to be the line that delivers windshield washer fluid the the sprayer on the hood that fell out and was just sitting there.

 

Cherry I don't think he's too worried about the 4wd working, my bet is it won't at all seeing as it's a 2wd lol.
I agree that vacuum box in the fenderwell is a PITA to get at & pics would help. It could run to a T that goes to the valve cover, brake booster or be the windshield fluid line... try them & see where the fluid sprays.

 

It was a long day and i was tired leave me alone lol. But hey i didnt give him any wrong info. His 4WD wont work with it unplugged.. it still wont work after its plugged in but thats another issue

 

its 2-wheel drive..lol..but it has nothing to do with my windshiled washer..It has to be something with vacuum line..I will try to get some pics..

heres the pics of the T and on pic 2 i have the vac line sitting on top of brake booster to show ya..

 

i have that hose also. try looking under your air intake . it looks like it goes to your egr . not on valvecover , but it sits on the manifold . should have 2 connections .a big one and a small one . that should go to small side . in your third picture does one of those hoses go to a loom that goes thru firewall, and the other one goes ? that is the one that i am having trouble finding a home for and am presently blocking off with a bolt. thx

 

That hose in the 2nd pic goes to my BOV (blow off valve) for the super charger so I'm not sure where it was originally. But it is a good idea to block it off until it's proper home is found.

 

all three pics are of the same vacuum line,just showing you different views..its all one vacuum line..Anybody got any pics where it hooks upto?? ohhh btw theres no suction coming from the vacuum line..it has to go somewhere..

 

It plugs into your intake manifold. There should be a nipple somewhere under your air cleaner intake tube on the drivers side of the intake close to the middle. It shoud be pretty easy to spot.
