- Terminal 53 receives voltage to operate the wipers in first speed.
- Terminal 53a supplies positive current for setting the wipers to their end position.
- Those. The wiper motor receives positive current through this terminal until the wiper motor is in the park position.
- Terminal 53b supplies voltage to operate the wipers in second speed.
- Through terminal 53e, the wiper motor is braked when the wipers move back after being switched off, so that the wipers do not go out of the park position.
- Terminal 31 provides ground contact.
Tip: When the ignition is switched on, the wiper blades must not be blocked out of their original position, for example by snow or freezing. In this case, voltage is continuously supplied from terminal 53a. Because the wiper motor cannot rotate due to blocked brushes, then after a certain time it will burn out.
