What is the reason for the Audi A4L wiper not moving?

Wiper motor failure is generally caused by issues with the wiper motor itself or problems with the wiring. Introduction to wipers: The wiper is an important accessory installed on the windshield, and its function is to remove rain, snow, and dust that obstruct the view on the windshield. Therefore, it plays a crucial role in driving safety. Basic structure of wipers: Electric windshield wipers are driven by a motor and generally consist of a wiper arm, wiper blade assembly, rubber blade, blade holder, blade support, wiper arm spindle, wiper base plate, motor, reduction mechanism, drive linkage, drive linkage hinge, wiper switch, and wiper switch knob. Of course, wipers equipped with a wiper ECU also include an electronic control unit (ECU).
As a car owner with over a decade of driving experience, if the wipers on an Audi A4L stop working, it’s most likely due to a blown fuse, especially after sudden failure following rain. Alternatively, the wiper motor might be faulty—if it gets waterlogged or worn out, it won’t start. Wiring issues could also be the culprit, such as loose plugs or aging short circuits. Sometimes, the wiper switch may have poor contact or malfunction, and control module failures are more complex. Last week, I encountered a similar situation—driving in the rain was particularly dangerous, so I had to turn on the hazard lights and pull over. I checked the fuse box located under the steering wheel myself, but it’s best to let a professional repair shop handle it to avoid accidents. For prevention, regularly clear debris around the wiper arms to prevent dust buildup in the motor. Proper maintenance can save a lot of trouble. Safety comes first—don’t overlook these minor faults.
