    You got those little round ones or a larger rectangular vent? The larger ones are readily available and easy to change.

    I would buy replacements, not that expensive. If you want a temporary fix remove the vents and cut cardboard to fit inside the hole and replace the vent (sometimes a pain to reinstall the vents). Another would be duck tape on the outsides of the vents, but when removing it may peal the paint off them.

    If the vents are metal, get a piece of magnetic material and slap it over the vent. I used to do that at work when the air blew directly on me.

    I have seen magnetic sheets that are sized and marketed for this purpose. If money is a problem, get a hold of some styrophone from packaging . Tape it on the inside. Or even use bubble wrap .
