    Hey guys on my cobra the AC only blows on vent. I know from research this is likely a vacuum issue. Under the hood into the firewall we are good. I can’t seem to see where the vacuum hose goes next before it gets to the center column behind the radio.

    What am I missing!??

    Thanks!

    Drop the glove box (all the way, push in the sides) its behind there. Just posted this to someons in another thread. There is a little manifold back there with a bunch of colored soft vacuum lines.

    Had one pop off swapping dashboards once. Same symptom.

    open. Go to top left menu.
    Svt documents
    Scroll down
    Red icon on left where paragraph starts is the full version for pc if you click on that.
    When you read paragraph
    Hard copy. Highlighted in blue.
    That’s small cell version
    Use Adobe reader
    Click above and a contents menu will drop for faster lookup in manual

    In here you will find our service manual.
    Small version works on cell and has
    All the information on vacuum hoses
    Where they go and how to test.

    there is a holding tank and some check valves also inline for this

    some of the door valves may not be accessible without dash removed

    but read it has a trouble shooting guide to follow
