    i don't see a hose



  • knockknock_1 Jan 03, 2009

    I found the blending door and it works.But i went to the drivers side and looked up under the dash and seen a plastic arm.When i moved it up the air started blowing out of the other vents.When i pushed it up and let it go,it slowly fell back to the down position.It would not stay where it was suppose to stay.What is this called? I didn't find the vacuum hose either.I looked around the throttle body and near the manifold.I don't see one with a nipple

    DEFENITE IS A VACCUM PROBLEM. JUST KEEP LOOKING AROUND THE FIRE WALL AND PASSENGER SIDE ENGINE COMPARTMENT. CHECK ALL VACCUM HOSES YOU BOUND TO FIND IT.

    THE REASON THAT BLEND DOOR GOE BACK DOWN IS BECAUSE OF NO VACUUM TO HOLD IT UP

My air conditioner blows air out on top by the window and on the floor but not in the middle on the dashboard. What part do i need to fix this and where is it located in the dashboard or under the hood?...


  • If the AC/heater air control doesn't work, you most likely have a vacuum line broken. All the air flow doors in the heater system are vacuum operated and without it the air will blow out of the windshield defrost vents. The common place for a vacuum line to break is under the hood where the lines pass near a hot area. The vacuum lines are normally a rigid black plastic tubing about 3/16 inch in diameter. They run across the engine compartment fastened to the section just below the wipers and air vent. The tube goes through the dash, usually near the steering column. When the tubing has been hot for long time it becomes brittle and cracks or breaks. Trace this tubing looking for a crack or break. The easiest repair is to cut out the broken section and replace it with rubber hose of the correct diameter. The hose needs to have an inside diameter that will fit snugly on to the vacuum tubing.


    Thanks for using FixYa.

Heater air will only come out at windshield


your a/c controls in this vehicle are vacuum operated. you more than likely have a vacuum leak that can be under the hood or under the dash. take a look under the hood and inspect all of the vacuum hoses, mainly the small colored hard plastic hoses. if your car also runs poorly that means you may have a leak in your engine vacuum, check larger black vacuum hoses and rubber seal on brake booster that manifold vacuum hose goes to. if no leak found under hood check those colored hard plastic hoses. with any luck you'll have heat blowing throuh your vents in no time.

What would make the air come out of defrost when vent is selected


Check for a bad vacuum hose under the hood,or the vacuum reservoir,one or the other is causing this,and the vacuum will be under the hood going into the firewall inside the car.If this was at all helpful,please rate,thank you.

1987 300z ac air only comes from the defrost. mechanic said not vacuum hoses under the hood.


Locate vacuum hoses that go from inside switch to actuator doors. Either switch is leaking, hoses are leaking or kinked or actuator is leaking. Listen for hissing noise under dash at idle or obvious bad hoses.

Vacuum Controlled A/C Blend Door Issues


Check the white vacuum hose going to your recirculation vacuum motor under the hood to the right side of the fire wall. It runs inside a wiring harness. The hose will get brittle and break apart. Start there it is the most common vacuum leak on a ford truck.I hope this helps.

Fan motor works and blows air to floor, dash, etc. but just stopped blowing air to the defrost. need help


Hi my name is Allen!

There are three possible causes with this problem, the first is the one we see the most, which is a vacuum problem under the hood near the heater core hoses, as this is where the vacuum hose comes out for the operation of the doors. The second could be a broken door or some thing blocking the door from working properly. The third and most uncommon is the control head itself has an internal problem. I would start with the vacuum under the hood.

For further asistance you may reach me at FixYa!

Air conditioner blows through defrost vents instead of dash AC vents when engine under load. Vacuum tank under hood holding pressure. Tested this by building vacuum and turning off truck. Then...


LOOK AT THE WHITE PLASTIC HOSE GOING TO THE RECIRC VACUUM ACTUATOR UNDER HOOD. THIS IS ON TOP OF A/C BOX BY RIGHT SIDE OF FIRE WALL YOU WILL FIND THIS HOSE IS STARTING TO COME APART REPAIR HOSE AND PROBLEM FIXED.
