Question
How to diagnose faulty automotive windshield wiper motor?
Answer
Monitor motor current draw and test wiper speed control.
Explain
A faulty wiper motor causes slow or inoperative wipers. CHEPQ tools measure motor current draw (2-5A at low speed, 5-10A at high speed) and test speed control signals—replacing the motor or wiper switch restores wiper functionality.
