What Causes Car Wipers to Stop Working?

[DiJulianna]

When car wipers stop working, it indicates a malfunction. You can try opening the hood to check if the transmission linkage is dislocated or inspect whether the fuse is intact. For more professional diagnosis, you can disconnect the motor wire plug, turn on the power, and use a multimeter to measure if there is voltage. If the fuse is intact but there's no voltage at the motor, check the wiring and the turn signal combination switch. If normal voltage is detected at the wiper motor when the power is on, the motor may be faulty. When car wipers fail to move, you can check the following possible causes: 1. Open the hood to check if the transmission linkage is dislocated (this is the most common cause). 2. Check if the fuse is intact. 3. Disconnect the motor wire plug, turn on the power, and use a multimeter to measure if there is voltage. If the fuse is intact but there's no voltage at the motor, check the wiring and the turn signal combination switch. 4. Check if the motor is burnt out—a burnt motor usually emits a scorched smell. If normal voltage is detected at the wiper motor when the power is on, the motor may be faulty.
