Vacuum Diagram
#1
![Default](/forum/images/icons/icon1.gif)
I have a 99 Blazer 4 x4, 4 door, 4.3 (W) engine, automatic transmission and I need a vacuum diagram. There is a vacuum line on the firewall by the wiper assembly that has a "T". One line goes across the engine to the right front of the vehicle, one goes to a connection on the left fender wall and the center one goes to where I don't know!! The original diagram is long gone. Do any of you guys know where I may get a diagram or find out where the lines go and what they do??? Thanks.
