    Seems a common issue. Defrost control lever got stiff and will not
    move to defrost position. How do I get to the working end of the cable
    to lube it or the door (valve) or clean bad foam away?

    Take the dash radio/vent control cowling/cover off, look in
    there with a flashlight, down the throat of the vent duct.
    You'll probably see a balled up bunch of black cloth that
    prevents the proper opening/closing of the vent duct. I removed
    that black cloth by using a combination of a a bent coat hanger
    and a long pair of needle nose pliers. Had to rip it out in
    pieces. I then lubed up all the internal vent control linkages
    and it now works great. Oh, also had to use a bent up paper clip
    as a replacement spring retention clip as a small piece of
    plastic used as the spring retention broke off from that plastic
    post. The excess force I used when trying to work the stuck vent
    evidently broke the piece off and thus noticed the spring kept
    popping off the post. Try to get all that fabric cover off that
    you see while working it back and forth. Leave the foam on
    though, at least I did. Hope this helps.......
