Bad "blower fan thermal switch".  This switch is supposed to close
when the engine warms up.  It's function is to prevent the blower fan
from blasting cold air into the car before the engine has had a chance
to warm.  On non-turbo 5K cars, this switch located near the #1 cylinder
and on turbos, in the coolant pipe just under the warm up regulator.
The defrost mode overrides the thermo switch.

A bad ignition switch?
