    the AC is out of order due to the blower's wire system problem. the blower does not work in ON position of thermostat either. However, when the two power wires are directly connected to the blower's wires, both ac and blower work. In such power connection, the blower is 24-hours work and can not be controlled by thermostate and/or AC temperature. Now, I have to let the blower 24-hours running to keep the AC's function. Could you help me to find where is the problem for the blower wire system? which part is malfunction which can not start the blower?
    Thanks.

    Could be the fan relay. This sort of thing is common with systems that have the blower relay on a control board.
