Sorry for the delay, I had a automotive training class the last 2 days.A blower fan staying on is caused by a failed blower motor resistor. The blower fan will draw to many amps from the resistor and causes it to fail. As the blower fan ages it develops a high amp draw. For a long term repair it is highly recommended to replace the blower fan and resistor.
