    You're on the right track going after the S2. To narrow it down, first check the S2 coil for magnetism. If it has it, go after the valve then. Remove, clean, manually shift it's internal spool, or replace etc.

    If you find it there is no mag, start back tracking the light green wire through the harness with a testlight looking for battery voltage until you find where it gets lost. Much of the time it's at the grill plug or controller plug. And occasionally it's the controller itself.

    A fast check for mag and then the test light if necessary will narrow it down quickly.
