Re: Climate Control Head Problems on an '88 5KSQ

More than likely, the problem is the blower motor rather than the
controllers.  Did you hear any squeaks when the blower did work recently?
That's a dead giveaway for a failing motor.   My blower motor became
intermittant last spring after squealing and squeaking for half the winter.
  I think the blower motor is a bit cheaper than the new control head, but
a lot more difficult to change.
