What are the four wires of the Tiguan electric fan?
2 Answers
The four wires of the Tiguan electric fan consist of two power wires, a ground wire, and a control wire. The radiator fan fuse is located in the fuse box in the front compartment of the engine. A blown electric fan fuse will prevent the fan from operating and requires timely replacement. A damaged electric fan fuse affects the fan's operation, leading to abnormal noise in the radiator's cooling. Below are the reasons why an electric fan may not rotate: 1. Poor motor lubrication: Poor lubrication of the motor can cause the fan not to rotate, as the motor cannot move when the blades are installed. 2. Motor overheating: Overheating of the motor reduces its load-bearing capacity and effective power, making it unable to drive the load. 3. Reduced capacitor capacity: A decrease in the starting capacitor's capacity reduces the motor's starting torque, preventing it from driving the load.
When I drove the Touareg, I studied the electric fan. Those four wires each have their own functions. The basic components are the power supply line, which provides electricity to the fan motor; the ground wire connects to the car body to complete the circuit; the control signal line comes from the engine computer to adjust the fan speed; and there's a feedback line used to monitor the fan's status and report back to the system. These wires ensure the engine temperature stays normal and prevent overheating. In daily use, if the fan doesn't spin or makes unusual noises, checking whether these wire connections are loose or corroded is key. The Touareg's cooling system is quite good, but during regular maintenance, having the technician check the wiring connections can help avoid breakdowns. A properly functioning fan is crucial for ensuring the air conditioning cools effectively.
