unkl300d, Yes I was referring to the climate control servo. Mine doesn't have the mono valve.
I could mail that chrysler (Imperial I think) part back to chrysler. But their people might get the bright idea to reintroduce this part to some of their new models, which would NOT be a good idea.
I better let this part fade into obscurity where it belongs.
I will repost to this thread when I get around to replacing the servo unit with a ball valve. But right now it's much too cold to think about that.
