I have been dealing with vacuum issues with A/C. I'm going to go through and change all vacuum lines at the intake tree and under the dash. Can anyone tell me where to go for those little pesky vacuum lines. Advance auto/AutoZone sell any standard lines? Thanks

    I recently bought several sizes and lengths at Advance. Instead of just asking I went in the back with the guy (after politely asking of course) where I was able to see and compare the various sizes that they have on reels. Got exactly what I wanted.

    You can replace the ends of the pesky lines with standard vac hose.
    Is it the lines or the check valves? engine side, by the a/c dryer? My 98 has 2 check valves there, when failing, they cause the a/c face vents to shut down during acceleration.

      How do I check to see if these check valves are failing (by the ac dryer)?

        They are a one way valve. passing air only in one direction. Simple check is to remove and suck on em. They will only allow air in one direction. This will only pick up fatal leaks. Little leaks may not show up by sucking on them.
        What is your failure? Are the face vents shutting off during acceleration and coming back on after?

          Yes the face vents are shutting down on acceleration. There is also hissing coming from dash on all vent positions except defrost setting.

      While your doing all of that with the hose's try this, remove the vacuum tree that all the hoses hook into the intake right behind the throttle body--it's held on with a 10mm bolt--take it out --put some sensor safe form a gasket material on it and glue it back in--let set
      overnight--you'll be surprised of how smooth your ride will be after that.

        Has anyone used these hoses? At bottom of page on link they show volvo kits with different sizes. Would any of these work on the 960? Any idea what sizes come off the 960?

        thanks guys for your responses. This weekend will be busy with that vacuum stuff and tonight it's new control arms, ball joints, discs and pads. Gotta give this thing a refresher. Later.
