What are the reasons for the failure of the intermittent wiper setting on the Buick Excelle?
1 Answers
The intermittent wiper setting failure on the Buick Excelle may be caused by the following reasons: 1. Internal short circuit in the motor: After opening the car hood, you can see the wiper motor. You can touch the wiper motor by hand. If it feels hot, it indicates an internal short circuit in the motor, and replacing the motor can solve the problem. 2. Damaged wiper blades: If you usually neglect the maintenance of the car wiper blades and find them severely damaged during rainy days, making them unable to work properly, replacing a set of wiper blades in time will suffice. 3. Linkage failure: The wiper linkage has many connection points. If these points have issues, the wiper will not work properly. You can judge whether it is a linkage failure by observing the operation of the wiper. 4. Blown wiper fuse: To protect the car's circuits, each electrical device is equipped with a fuse. If the wiper does not work, you can check if the wiper fuse is blown and replace it with a spare fuse from the car. 5. Possible issue with the wiper switch: Although the wiper switch is not frequently used, car electronics themselves are unstable. Therefore, if no issues are found in the above checks, you should consider that the wiper switch might have a problem. You can use a multimeter to measure the condition of the switch or directly replace it with a new one for testing. 6. Wiper circuit failure: Checking the wiper circuit is a complex and time-consuming task. You need to be proficient in using an automotive multimeter, measuring voltage, resistance, and current, and combining this with practical knowledge to identify the circuit fault point causing the wiper to malfunction.
