That's my bet. Unplug the connector (at the bottom, firewall side, of the
rad) to confirm/deny that the switch is bad. When you unplug the switch the
fan should not come on at all (unless the after-run kicks it on when the car
is hot) so don't let the car sit there running (obviously:). Only do this
with the car off (and cool) so you don't lose or injure any digits with the
fan perilously close by.

The CGT's don't have a resistor pack because they use a single speed fan.

Later!
