What Causes the Jetta Fan Not to Work?
2 Answers
It may be caused by a malfunction of the car fan's relay. Here is relevant information: 1. Overview: Jetta is an automobile brand under FAW-Volkswagen Automotive Co., Ltd., a joint venture of the German Volkswagen Group in China. Its first product, the Jetta (Jetta-MK1), was launched in Europe in 1979. 2. Other Information: On February 26, 2019, Volkswagen's first-ever sub-brand, the Jetta brand, was officially unveiled in Wolfsburg, Germany, the headquarters of Volkswagen. This new brand is scheduled to enter the Chinese market in March of this year and will become the third brand under the long-term cooperation between Volkswagen and FAW-Volkswagen.
Driving a Jetta for so many years, the fan not spinning is really annoying. The most common issues are the fan motor itself being damaged or burned out due to overheating, especially in older models where the motor is prone to problems. In terms of wiring, loose connectors or aged and broken wires can cause poor contact; a blown fuse is also a frequent culprit—try replacing the corresponding fuse in the engine compartment's fuse box. When the temperature sensor fails, the fan won't receive the signal to start; relay faults are also common. A simple test is to unplug and replug the electrical connector to see if there's any response. However, be aware that driving long distances with a non-functional fan can cause the engine to overheat and fail. If troubleshooting doesn’t work, seek professional help immediately—don’t risk it to save a little money. Regularly maintain and check if the fan operates smoothly, and clean dust to avoid blockages and extend its lifespan.
