Your question needs clarification - are you asking about the heater blower fan or the motor cooling fan? The heater blower may have a series resistor that is used for running the fan at slow spped. The resistor may be inside the box that holds the heater blower. It could be an open coil of wire that looks like a spring. The motor cooling fan usually runs at one speed, thus there is no series resistor. Are you instead asking about the resistance of either fan motor. You might find that listed in a repair manual. Try your public library.

why does gas splash out when filling a 2002 chevy prism
Well, In the 2002, the blower motor resister is behind the glove copartment. You might want to check there.
If you are missing some or all low speeds on the blower motor but still have high speed that would be the resister. The resister is located under the hood, attached to the HVAC (heating, ventilation and ac) box close to the blower motor. It has a removable electrical plug attached to it and is held in place with two small screws.
I would suspect the blower motor speed resister is shot.
The heater blower for a 2002 Chevy Silverado is mounted under the dash. It is on the passenger side, in the heater housing.
When this happens its most likely the blower motor resister that is bad.......
The blower motor speed resister is burned out. This part is available from your local auto parts stores. The resister is located in the engine compartment, on the firewall, on the passengers side.
Short of it is the resistor controls the fan speeds for the blower. Easy to replace and to my knowledge only available through a dealer.
