Re: 2005 Astro Smoking multiple A/C Blowers

A poor ground for the blower motor can burn up the motor AND the resistor. Disconnect the connector at the blower, measure resistance to ground on the black wire... must be less than 5 ohms. Did you remove the resistor pack and visually inspect it? Sometimes you can see burn marks on the printed circuit board.
