This is more than likely caused by the actual fan switch. As I am English, I have no idea what a Chevrolet Trailblazer is, or what it looks like even, but there are things which are common to all or many vehicles.

The low speed and second speed blowers doesn't work for the blower motor?

the reason blower does not work on all speeds, is the fan blower motor resistor. The resistor is a 4-5 step series circuit, 1 resistor is added for each reduction in speed. If one burns out then so will all speeds below it. The "high" circuit usually has a separate fuse and bypasses the resistor altogether.

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.

If you're talking about the inside blower motor you need to check the blower motor resistor and or wiring to it as it can cause this problem. Usually the slower speeds go first though. Could also be caused by the dash switch.

Could i bad ground wire cause you high speed not to work on your fan?

No, try relpacing the blower motor resistor. that is usuially what goes wrong with them when other speeds work and one or two dont. hope this helps
