The control heads don't fail very often. The heavy hitters here are blower motors and blower resistor modules. Start the diagnosis again from the top. At the blower motor, do you have power and ground on the two wires? If not, which one DON'T you have out of the two?

Sorry for the late email just received it I had a death in the family.

Not a problem, I was likewise unavailable. Blower works with direct power. Good, so that means we're either missing the power or the ground at the motor connector. Use a test light to determine which of those things is missing. Both run through that resistor module, but before we make a decision about what to do, we need to find out which leg is missing.
