The heater control module can reduce the heat of the cooling system and improve engine efficiency by controlling the fan.Timely replacement of faulty resistors ensures efficient cooling performance. Easy to install, can be replaced directly without the need for professional skills or complex tools.Old or damaged modules can cause the fan to stop rotating or malfunction, resulting in high temperatures, reduced heat dissipation performance, and engine overheating. The blower control resistor is made of high-temperature plastic and has undergone quality testing to good performance even after long-term use.
