    A/C vents close on their own - any ideas ?

    As I'm sure you guys are getting to know my car and my issues by now, yes I've got another one. I swear I'm not a drama queen!! I just keep finding problems with this car!

    I'm sitting in the car with the A/C on listening to the radio with my 2 year old and she discovered THE problem.

    When you turn the circular knob to the full open position on each of the vents they then creep closed, each of them on their own. DAMMIT! It's the little things that start to add up that really tick me off.

    This is not retardation, this is real life. Anyone? We live in Phoenix, heat capital of the world, and my A/C vents close on their own! ? ... ! .. ??? ?

    Anyone?

    I have been holding back SO much, but I miss my F150 right about now so so so so much. I already know I made a mistake, I'm just hoping it's not as bad as I'm thinking this going to be.

    Re: A/C vent levers - yeah, another problem

    so - either take a vent out -
    discover what would "tighten it up" -
    and fix it -

    or hit the junk yard and find some "stiffer" vents -

    if you don't want to try either method -

    just jamb a stick against the wheel - so it can't move -

    Try stiffer vents? Take it apart and tighten it up? Really? Yet another thing I'm having a hard time wrapping my head around on how to do this, any possible screen shots or pictures to give me half a clue?
    I cant see how this as an item to tighten. ...?...

    I'll remove the balled up pieces of paper that I currently use to keep them wedged open and replace them with toothpicks.

    Thanks a lot.

    No - he means you need to remove the vent with problem, see why it's loose, and jam a toothpick into the rotating parts or bearings so it wouldn't be so loose.

    It's possible that someone broke the vent while trying to remove it. These suckers break if you aren't careful.

    Mine close on their own also, when I had dash apart I took a look at them. Seems the factory saved a nickel and left out a ball bearing they may have used in the past. I found some beads basically that fit between the mechanism and the indents on the side. Now they stay open 95% of the time. The bead went between the arm that opens/closes and the side of the vent itself.
    To remove the vent is a pain till you figure it out, there is a small clip on both sides that you have to pry towards center of vent and it slides out. Try a search for remove vents...

    Re: A/C vents close on their own - any ideas ?

    to remove the vents -
    use an old credit card - cut in half lengthwise -
    use the "original" rounded sides pointed to the outer edge -

    there is a locking tab on the upper left - and lower right corners - of the vent -

    insert one piece of credit card between the top/left corner of the vent -
    and the hole in the dash - you need to sort of "saw" it in place at an angle -
    so - you are wedging the credit card
    OVER the vent on one side and UNDER the vent on the other side -

    the goal is to get the credit card between the locking tab -
    and the dash -

    do the same to the lower right -

    then wrap some electrical tape around the jars of some long-nose pliers -
    this is so you don't scratch up the vents -

    get a good bite on the center of the middle vent louver -
    push the vent in and out until it comes out -

    ----------------

    getting the first vent out will be a pain - and will take some time -

    all the others will take less than a minute each -
