Where is the Jetta fan fuse located?
5 Answers
The Jetta radiator fan fuse is located under the cover panel to the lower left of the steering wheel. The car water tank generally refers to the car radiator, which is part of the car cooling system. The radiator in the engine water cooling system consists of three parts: the inlet chamber, the outlet chamber, the main plate, and the radiator core. The principle of the radiator fan is to increase the air circulation of the heating components, continuously dissipating heat through the airflow. Method for adding water to the Jetta car radiator: Turn the pressure cap counterclockwise. If a hissing sound is heard, wait until the sound disappears before opening it; Add an appropriate amount of coolant to the coolant expansion tank until the liquid level reaches between the MAX and MIN marks on the expansion tank; With the coolant expansion tank cap open, start the engine; After starting the engine, the coolant in the tank will slowly decrease. At this time, add an appropriate amount of coolant to the expansion tank until the liquid level reaches between the MAX and MIN marks on the coolant expansion tank; Reinstall the cap, ensuring the pressure cap is hand-tightened and fully seated.
I've been a Volkswagen mechanic for over a decade. The Jetta's fan fuse is located in the engine compartment fuse box. Open the hood and look towards the front left – the black box marked 'FUSE' is what you need. Open the plastic cover, and you'll find a fuse location diagram on the back. The fan fuse is usually labeled with an SC prefix, and in older Jetta models, it's commonly found between positions 20 to 30. Remember to disconnect the negative battery terminal before replacement. Use needle-nose pliers to vertically pull out the blown fuse, then replace it with a new 15A red fuse. Just helped a customer with this last week – these cars often blow fuses due to aging fan wiring, so make sure to also check if the fan connector shows any oxidation or blackening.
Last time my Jetta's fan wasn't working, and it turned out to be just a blown fuse. The location is super easy to find: open the engine hood, the black plastic box with clips behind the battery is the main fuse box. Use a phone flashlight to look inside - there's a diagram on the cover for reference. For Volkswagen group vehicles, the fan fuse is usually in the second row on the right, marked with labels like S42 or S51. I recommend keeping a $5 circuit tester handy - always test both metal contacts for continuity before replacement. The repair shop owner also reminded me that a seized fan motor can blow fuses too - only when the blades rotate freely by hand is it truly a fuse issue.
Car enthusiasts all know that the Jetta's fan fuse is located in the engine compartment fuse box, with the exact position varying by model. For older models like my 2015 version, the 30A large fuse is in the fourth slot from the left in the third row, the rectangular transparent plastic type. When working on it, first lock the car and cut the power, prepare a Phillips screwdriver to loosen the box's fixing screws, and be careful not to pull on the wiring when lifting the cover. The most crucial point is to replace it with a blue fuse of the same amperage. Roadside shops often incorrectly use 25A instead of the factory 30A, which can easily cause the fuse to blow again.
For DIY enthusiasts, here's how to find it in 30 seconds: 1 Open the hood 2 Lift the cover of the front left black fuse box 3 Check the icons on the back of the cover to locate the radiator fan symbol 4 Pull and insert the corresponding slot. Most Jettas use a 30A fuse, simply plug it directly into the slot with the fan pattern. But note that fuse breakpoints are divided into fast and slow blow types—those with a 'T' letter in the middle are slow blow. Mechanics say the fan's starting current is high, so this type is a must. Last time I replaced it with a regular type, and it blew again on the highway.
