Nissan sentra 1994. Just replaced melted blower motor speed control switch. The maximum speed switch setting contacts were melted into the plastic switch enclosure. After replacing the switch the wires coming into the switch and going out to the motor are very hot, burning my fingers... I have checked the motor, it draws about 15Amps from battery when engine is not moving (12V). It could be not accurate measurement since I lost some power on multimeter probe contacts at such high currents...
Is this a normal current draw for the blower motor in a small car like sentra? What can I do about overheating wires ? The wires do not look thick enough for 15A currents running through them. Also, the socket/plug for the motor speed switch contains regular-looking quickconnects, is it possible to disassemble the switch receptacle and replace/rework new quickconnects ?
