The connector for the blower speed control switch has melted.Which of the following is the most likely cause?
A) An open in the blower motor switch.
B) High than specified blower motor current draw.
C) A shorted blower motor resistor block.
D) An open blower motor resistor block.

Question

Quizplus · Accepted Answer

A higher than specified blower motor current draw can cause the connector to melt due to overheating. This is commonly caused by a failing blower motor or a blockage in the HVAC system, which causes the motor to work harder than it should. In contrast, an open or shorted blower motor switch/resistor block would not directly cause the connector to melt.
