    I take it we are talking about the 3 button push control unit that is mounted under the dash? If this is it then, any light spring with a slight pull will work. The spring puts tension downward on the locking bar. Nothing high tech.

    Or are you talking about the heater control valve in the heater hose near the core?

    In the picture, it goes on the same side as the bimetal spring.
    From the little post on the right to the larger shaft.
    On my C101, it is on the side opp of the bimetal spring.
    Differant versions/years?

    Try Walck's for parts to fix your heat riser valve.

    I've found it invaluable to have a factory shop manual (FSM) on hand to look up stuff like this. In fact, more than once I've taken one of my FSM's into work to blow up a diagram or a photo on the copier to get a better view of what I'm getting into.

    Yep. I have two FSM's- a nice, clean, un-tattered one, and a somewhat dirty, greasy, sorta falling apart version to really "use"..:)
