What is the reason for the sudden failure of the Buick Excelle's wiper?
3 Answers
The sudden failure of the Buick Excelle's wiper is caused by a blown fuse or a burnt-out motor. The following are the related details: Blown fuse: The wiper may stop working because the fuse (which prevents circuit overload) has blown, causing the wiper to malfunction. In this case, you need to open the fuse box and check whether the corresponding fuse (refer to the instructions on the cover) has blown. Burnt-out motor: The probability of a motor burning out is actually quite low, but it could also be due to quality control issues. Turn the car's ignition switch to the power-on position, then open the front hood and activate the wiper. If it is not damaged, you should be able to hear the sound of the motor running, and the sound is quite noticeable.
I was driving in the rain the other day when the windshield wipers suddenly got stuck, which really gave me a scare. There could be several reasons for this, such as the wiper motor burning out, which is quite common; or a blown fuse, located in the fuse box under the steering wheel, which can be easily checked; the wiper linkage might also be stuck, which can happen when it freezes in snowy or icy conditions; poor circuit contact or a faulty switch could also be the cause. Don’t panic—pull over safely, turn on the hazard lights, and manually check the fuse first, as it’s the safest step. Many people mistakenly think they can fix minor issues themselves, but using tools like wrenches haphazardly can easily damage parts. For safety, it’s best to take it to a professional shop for inspection. For prevention, regularly clean debris under the wiper blades to prevent leaves and twigs from accumulating, which can help extend the lifespan of the wiper system.
As someone who loves tinkering with cars, I've dealt with many similar issues. Wipers not moving are mostly caused by blown fuses or motor failures, especially prone to short circuits in humid weather; rusted and stuck wiper linkages are also common - always disconnect power before working for safety. If you understand circuits, using a multimeter to test current flow toward the switch end can save guesswork time; but avoid touching wiring without experience, as incorrect connections risk dangerous fires. The wiper system relay is often overlooked - it controls current flow, and unstable signals from aging can cause wiper failure. I recommend checking for loose wiper mechanisms in the engine bay after each car wash; making this a habit prevents sudden troubles.
