What are the symptoms of Volvo wiper failure?
2 Answers
Volvo wiper failure symptoms are as follows: 1. The wiper blade cannot reset itself: The wiper motor cannot stop at the automatic stop position, mostly due to a damaged control switch, poor operation of the electric automatic resetter, or an open circuit in the connecting wires. 2. The wiper motor does not rotate: This can be caused by a blown fuse, loose or poor contact in the wires, a damaged or poorly contacted wiper control switch, an open circuit in the armature winding or damaged gear in the reducer, loose coil connections, damaged or stuck brushes, or a locked rotor. 3. Slow wiper movement: This may result from low voltage or poor switch contact, dirty contact surfaces between the wiper blade and the glass, poor lubrication of the motor bearings and reducer gears, poor brush contact, or overly soft springs. 4. The wiper motor does not stop after the switch is turned off: This is mostly due to sintered or stuck control switch contacts, a short circuit in the connection, or damaged automatic stop positioner contacts.
Volvo wiper malfunctions are quite common. I used to drive an XC90 and encountered several issues. The most obvious symptom was the wipers completely failing to work, getting stuck immediately upon startup, or suddenly stopping during rain, which was dangerously blurring visibility. Another sign was them jumping or shaking, not wiping cleanly and making squeaking noises. Sometimes, they only worked on high speed while the low-speed setting failed, possibly due to a wiper motor issue or a blown fuse. Even more annoying were intermittent failures—sometimes wiping fast, other times sluggishly, which could involve loose linkage or sensor problems. Lastly, failing to properly return to the starting position, stopping halfway and leaving half the windshield exposed, usually indicated a faulty return mechanism. These issues are especially dangerous on slippery roads, so it’s crucial to inspect the wiper system promptly and not delay.
