The only motor in the A/C (inside the "programmer", the misnamed box full
of vacuum solenoids, or separate, depending on year) controls hot/cold
mixture; the destination for the air is controlled by those solenoids
in the "programmer" which turn vacuum on and off that goes to vacuum 
actuators that move the appropriate air doors. Maybe he meant one
of the solenoids in the programmer; both broken solder connections and
malfunctioning doors seem to be common. Check for the former first;
the programmer is behind the glove box.

too long; when it finally opens, there isn't enough time to cool much before the
engine gets hot enough to require the fans - though if there's more than a brief
amount of time between the needle jumping and the fan coming on, I'd
say it's also *staying* to hot for a separate reason.
