the fan switch on my 72 only runs on one speed. is this a switch problem or a relay problem or both another question. what does the resistor do and could it cause a problem. thx in avance

If the one speed is high, the resistor is the likely place to start.

If problem were only on High it would be relay, on medium it is more likely the resistor.
