Question:

2006 chevy sivlerado manual ac. is my blower motor bad or what?

Fuses are good. When the keys on and I test for voltage at the blower motor connector with ac on high and low it shows 12 v.. when off it shows nothing, resistor makes click nosies when turning different fan speeds, what does this mean.

Answer:

If you get power to the blower motor in all speed ranges, then it is the blower motor that is bad. Make sure the connector is good not showing any signs of melting. It is possible the resistor pak is next since it needs the blower motor to help keep it cool. Since there is no air flow across the resistor or blower motor processor, it tends to get hot
You should get 12V at the blower motor .only when the selector is on high fan. Your voltage should drop down with every selection of a low speed. This is routing the power through the resistor pack, dropping the voltage, which drops the speed. If the voltage doesn't drop, your resistor pack is blown, or your switch is bad.
