Blower motor resistor in 2005 trailblazer is melted as is the male wiring harness that plugs into it. Is resistor the only cause of problem and how can I fix the wiring harness or must I buy new one?

The blower motor resistor is the common failure. It comes with the wires attached that plug directly to the blower motor itself. If there is another wiriing harness that is damaged then you will have to buy it too. The resistor failure has been linked as the only cause of the melted wires other than the blower motor itself. The motor can be tested with 12v power to it and it should run on high speed when tested.
