What is the reset method for the wiper motor of the old Audi A6?
2 Answers
Loosen the fixing screw of the wiper motor bracket. Here are the specific details: 1. Introduction to the wiper: The wiper, also known as the windshield wiper, is a blade structure installed in front of the windshield. It consists of a motor, reducer, four-bar linkage, wiper arm spindle, wiper blade assembly, etc. Its main function is to remove rain, snow, and dust that obstruct the view on the windshield. 2. Operating principle: The power source of the wiper comes from the motor, which is the core of the entire wiper system. The quality requirements for the wiper motor are quite high. It uses a DC permanent magnet motor. The wiper motor installed on the front windshield is usually integrated with the worm gear mechanical part. The function of the worm gear mechanism is to reduce speed and increase torque. Its output shaft drives the four-bar linkage, which converts continuous rotational motion into left-right swinging motion.
Just helped my dad reset the wipers on his 2002 A6 a couple of days ago. The reset procedure for this old car feels quite ceremonial. First, turn the key to the ignition-on position without starting the engine, then turn it off. Here's the crucial part—within 10 seconds, pull the wiper stalk downward and hold it for about three seconds, and the wipers will clunk their way back to the park position. Last time, it took me three attempts to succeed, probably because the battery voltage wasn't stable enough. After resetting, it's a good idea to check if the rubber bushings on the wiper arms have aged. When I took them apart, I found the linkage rods were rusty, so I sprayed some WD-40 to smooth them out. Older cars' electrical systems are prone to poor contacts, so if the reset fails, it's recommended to disconnect the negative battery terminal for five minutes—it's like rebooting the car's computer.
