On my '87 Camper with A/C, the resistor gives you the
1st (low) and 2nd (med) speed by inserting parts of
the resistor in series with the fan motor. The 3rd
(high) speed happens when full battery voltage is
applied to the fan motor, bypassing the resistor
entirely. The fan itself has no internal speed
control, only a positive and negative battery
connection.

Jumpering the radiator thermoswitch connector wiring
will test 1st and 2nd speed circuits (including the
resistor), but not the high speed circuit.
