Vacuum lines

[newb23]

Im havin a prob with my 97 ranger 2.3 vacuum lines, not all the lines are working, how can i find out where the problem is?

You could buy or borrow a vacuum guage to see if you're hitting proper levels...

Why do you say you are having problems though...does something not work (like heater vent door) or is the vehicle running rough...a bit more detail would help determine where to start...

the truck runs just fine, i cant get the heater to work it just blows air, the line on the bottom of the heater valve doesnt work, the line on the ERG dont work, and there is a round canister with 2 lines going in it they dont work either. I followed the line on the heater valve back to the cab but have no idea what im doing once i get there
