after cutting red and white wire whats and join upto resistor whats done with the other end of same wire?
 
Right I have a issue wired one resistor in turned air on on and still no slow speed fan nothing
Red white cut join to one end of resistor splice red and black and join other end but nothing happens when turn ac on it says to test after doing one plug
 
Right temp wired up nothing but if I remove rad temp switch and test that way they work
 
Have you connected the resistor to the right "half" of the red/white wire?........ I.e the half that comes from the connector, not the half that goes to the fan.
