    Similar vent problem

    I think the blend door is stuck on my car but I don't know if my car has one. Some cars have a vacuum controlled door and I checked the vacumm lines going into the firewall. It only blows out air through the defroster vents and the floor vents on any setting.

    Yep the blend door is stuck closed. Check all the Vac lines inside the dash.

      It was a simple fix, the parking brake vacuum hose was disconnected.

        I wish mine was that simple. All my blend doors work, but the seals on them are shot so air blows from everywhere. Yet another project that promises to be a horrible nightmare to fix.
