Common Symptoms of a Faulty Connector
A malfunctioning windshield wiper motor connector can lead to various issues that affect wiper performance:
Wipers Not Operating: The most obvious sign is the wipers failing to activate when turned on.
Intermittent Operation: Wipers may work sporadically, starting and stopping unpredictably.
Limited Speeds: Wipers operate only at certain speeds, ignoring other settings.
Wipers Not Parking Correctly: Wipers stop in the middle of the windshield instead of returning to their resting position.
Unusual Noises or Smells: Loose or corroded connections might cause electrical arcing, leading to buzzing sounds or burning odors.
