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.
