Types just controlling the fan speed generally just comprise of a few wirewound power resistors (or one resistor with a 3 or 4 windings), which have the effect of regulating the motor speed by reducing the voltage available to the fan. I am convinced that for the majority of fan issues, it's not the resistor that is faulty but the wiring connectors that dont have a solid connection. A good indication that you need a blower resistor is if your blower is only working on the highest speed setting. The reason for this is if pwm signal is 0 on computer fan, the fan will still spin at 30%. The most common symptom of a faulty blower motor resistor is a blower fan that only works on one speed, usually high. Last one Free postage. Almost :beer: time! While the blower motor will still run, you cannot change its speed. Wreck Code: P-12. This way, I can truly completely turn the fan off if needed. ‘HI’ is the only blower speed that doesn't depend on the blower resistor to function. Another symptom of a possible problem with the cooling fan resistor is issues with the cooling fan speed. Most 12V fans will run on from 7V to 12V.
