The heater blower fuse of the Tiida is located on the driver's left-hand side. There is a box to the left of the steering wheel containing fuses. The rear cover is labeled with fuse positions. Open the cover, and the back of the cover marks the locations of the fuses. The electronic fan fuse is located in the fuse box in the front engine compartment. Additional information: Fuse sizes: Small car fuse box; Medium car fuse box; Large car fuse box. Common injection molding materials include: PBT engineering plastic, with varying high-temperature resistance depending on the material. Classification of car fuse boxes: Fuse tube boxes and fuse strip boxes.
I remember the Jetta's heater blower fuse is usually found on the driver's side. Specifically, it's located in the fuse box under the steering wheel on the left, which is quite deep and a bit tricky to locate. You might want to crouch down first and feel upwards along the footwell. The plastic cover usually has various icons marked on it, and the heater setting is typically indicated by a heating element plus fan symbol. Older Jetta models tend to place the heater fuse towards the middle of the box, using that small blue 15A square-type fuse. Of course, remember to check the owner's manual to confirm the number, as the position might be slightly adjusted for different model years. If the heater suddenly stops blowing air, there's an 80% chance this fuse has blown. Never try to jump-start the AC directly by grounding it, as it could burn out the wiring. It's best to keep a spare fuse box in the car for easy replacement.
The heater fuse is usually located in the cabin fuse box. On Jetta models, this box is on the left side of the dashboard, and you'll need to remove the plastic cover in front of your knees to access it. The small fuses inside are densely packed, making them quite difficult to spot. It's recommended to disconnect the power before working on it to avoid short circuits that could damage the car's electronics. Based on my experience repairing Jettas, the heater fuse is often in the second row, third position, marked with a fan symbol and a curved line. However, for models produced after 2017, the position might have changed, so be cautious. If you can't find it, it's best to visit a 4S shop and let a technician locate it for you—their computer system can pinpoint the exact location, which is much more efficient than searching blindly yourself.
