    Unhappy Defrost Troubles..Help?

    alright so my front windsheild defrost vents seem to be blocked. i could put it on max and air would only come out of some of the holes.
    could they possible be clogged? if so how would i get to them to check?
    any suggestions?

    I would also check the inlet vents under the cowl, as they could be blocked with leaves and junk.

    More likely the blend door actuator. Search the forums for "blend door"
