Is It Normal for a Car Blower Resistor to Get Hot?
1 Answers
It is normal for a car blower resistor to get hot. The function of the car blower is to blow the cold air from the air conditioning evaporator or the hot air from the heater core into the car. When the blower is turned on, if the lowest temperature is selected, the outside air drawn in through the external circulation will be at the ambient temperature, which might be slightly higher because the air intake for the external circulation is usually located between the windshield and the engine compartment, increasing the temperature of the incoming air. Below are the functions of a car air conditioning system: 1. Temperature Regulation: This is the primary function of car air conditioning. In summer, the cooling system produces cold air to lower the temperature inside the car. In winter, except for large commercial vehicles that use independent combustion heaters, most vehicles utilize waste heat from the engine for heating. 2. Humidity Regulation: Humidity greatly affects passenger comfort. The humidity inside the car should generally be maintained between 30% and 70%. Standard car air conditioning systems do not have the capability to regulate humidity; this can only be achieved through ventilation or by using advanced luxury car systems that integrate heating and cooling. 3. Airflow Regulation: The speed and direction of airflow significantly impact comfort. If air is blown directly, the speed should be limited to a certain range when the temperature is appropriate. The speed can be adjusted based on passengers' living environment, age, health, and personal preferences. 4. Air Purification: The quality of air inside the car is crucial for comfort.
