the blower would stop working occasionally, Know will not work at all. I have tested between the red and black wire right before the resistor I get 12v. Between the red and grey (with black stripe) I get from 9-12v depending on the speed of the controller. I Put in new Blower Motor Resistor and am still only getting .03-.05v on the blower side. |

Could you provide the part number and the brand of the installed part? |

Check the terminal condition inside the three wire connector. Possible loose terminals. If that is okay perform your voltage tests with all connectors installed. You may have a voltage drop problem that will only show with a load on the system. |

I do I have a voltage drop after the resistor on the old and new one. I think I got a bad resistor.12v to less then one volt on both of them. |

Can you explain on which wires you are testing (color and harness connector) and what reference points you are using for both power and ground. |
