What Causes Intermittent Wiper Operation?

[LenaAnn]

Intermittent wiper operation is generally caused by the following reasons: 1. Check the wiper blades: If regular maintenance of wiper blades is neglected, they may become severely damaged and fail to function properly when it rains. Simply replacing the wiper blades will solve the issue. 2. Check the wiper motor: After opening the car hood, you can see the wiper motor. Touch the motor with your hand - if it feels hot, this indicates an internal short circuit, and replacing the motor will resolve the problem. 3. Check the wiper linkage: The wiper linkage has multiple connection points. If these points malfunction, the wipers won't work properly. Observe the wiper operation to determine if it's a linkage issue. 4. Check the wiper fuse: Each electrical device in a car has a fuse to protect the circuits. If the wipers don't work, check if the wiper fuse is blown. You can replace it with a spare fuse from the vehicle. 5. Check the wiper switch: Although not frequently used, car electrical components can be unstable. If no issues are found in the above checks, consider the possibility of a faulty wiper switch. You can test the switch with a multimeter or simply replace it with a new one for testing.
