Why does the Nissan Sylphy's wiper sometimes work and sometimes not?
2 Answers
The following are the possible reasons why the wiper sometimes works and sometimes doesn't: 1. Check the wiper blades: If you don't usually pay attention to the maintenance of the wiper blades, you may find that they are severely damaged and cannot work properly when it rains. In this case, simply replace the wiper blades in time. 2. Wiper motor failure: After opening the car hood, you can see the wiper motor. You can touch the wiper motor with your hand. If it feels hot, it indicates an internal short circuit in the motor, and replacing the motor can solve the problem. 3. Check the wiper linkage: There are many connection points in the wiper linkage. If there are problems with these points, the wiper may not work properly. You can judge whether it is a linkage failure by observing the operation of the wiper. 4. Check the wiper fuse: To protect the car's circuits, each electrical device is equipped with a fuse. If the wiper doesn't work, you can check whether the wiper fuse is blown and replace it with a spare fuse from the car.
Last month when I was driving my Nissan Sylphy, I also encountered intermittent wiper issues. Later I found the most common problem is poor contact in the switch. The switch in older cars tends to accumulate dust or wear out after prolonged use, causing unstable signals. Another frequent cause is blown fuses, especially during rainy days when current fluctuations are greater - the fuse may burn out. You can check the corresponding wiper fuse in the fuse box. There's also the possibility of loose wiper arm connections; driving on bumpy roads with strong vibrations may cause the wiper motor and linkage to disconnect, resulting in intermittent operation. I suggest trying this first: start the car and turn on the wiper switch, listen for any humming sounds. If the sound is abnormal or noisy, it might be a motor issue. Don't underestimate this - blurred vision in rain is extremely dangerous, so regularly check the switch and wiper blades. If problems occur frequently, it's best to keep a box of spare fuses in the car for emergency replacements. The wiper system is simple but can be life-saving in critical moments - don't push your luck driving on highways with faulty wipers.
