Why does the Nissan Sylphy wiper work intermittently?
3 Answers
Nissan Sylphy wiper works intermittently for the following reasons: Severely damaged wiper: If you usually do not pay attention to the maintenance of the car wiper blades, and find that they are severely damaged and cannot work properly on rainy days, you can replace a pair of wiper blades in time. Wiper linkage failure: There are many connecting points on the wiper linkage. If there is a problem with these points, the wiper will not work properly. You can check the operation of the wiper to determine whether it is a linkage failure. Fuse blown: To protect the car's circuit, each electrical device is equipped with a fuse. If the wiper does not work, you can check whether the wiper fuse is blown. You can replace the blown fuse with a spare fuse in the car.
I've been driving a Sylphy for several years and have encountered the wiper acting up. Last time it rained, the wiper suddenly stopped while wiping, then started moving again after a while. Later, I found out it was because the wiper linkage was rusted—that part under the engine compartment is prone to water accumulation and rust. Another time, the carbon brushes in the motor were worn out, causing intermittent contact issues. Problems with the combination switch are also common; the wiper lever under the Sylphy's steering wheel tends to have oxidized contacts after prolonged use. Corrosion from water in the wire connectors is even worse—last year after heavy rain, I found greenish corrosion on the pins. My suggestion is to first remove the wiper arm and check if the pivot moves smoothly, then test if the motor voltage is stable. If all else fails, replacing the motor only costs a little over 200 yuan. It's best to get it fixed before the rainy season to avoid being caught off guard during a downpour.
My Sylphy had the same wiper issue a while ago - it would swipe twice then stop during rain. I've identified several weak points in the Sylphy's wiper system: First, the motor connector tends to loosen (that black plug under the hood gets loose from vibration). Then there's the wiper relay in the relay box - its contacts get burnt causing intermittent current. Also, deformed wiper blade slots can make the arms jam (I found a cracked plastic clip when I disassembled mine). Electrical issues are trickier - loose fuse bases or rusty ground wires can cut power. Now during every maintenance I have mechanics check resistance values as prevention. You can't take chances with wipers in rain - once mine failed on the highway and I got chills down my spine.
