Short out the thermoswitch -- if the fan comes on that was the problem.  If
it doesn't, leave the thermoswitch shorted and short across the other
components in turn.  The one that you're shorting when the fan comes on is
the problem.  But *don't* short across the fan unless you like the smell of
smoke.  If none of the discrete components is the problem, time to trace
the wiring with test light or preferably  voltmeter.  If it comes to that I
can translate the Bentley diagram for you if necessary.
