Which of the following is the first troubleshooting step after discovering that the wipers do not work?

• A. to verify the wiper motor is physically stuck.
• B. to see if any other circuits are not working.
• C. to replace the fuse.
• D. to inspect the switch assembly.

Answer: (B)

When you first notice the wipers aren’t working, the initial step is to check whether other electrical circuits in the vehicle are also affected. This helps you quickly distinguish between a broader power problem and a problem isolated to the wiper system. If other circuits aren’t functioning, the issue is likely in a common power source or distribution path—things like a blown main fuse, loose battery/ground connections, or a failing power supply. You’d then verify power feeds and fuses and inspect the battery and related wiring. If other circuits are fine, the fault is more likely confined to the wiper circuit itself, so you’d next zero in on components within that path—such as the wiper switch, the motor, the wiring, or the wiper-specific fuse. This approach saves time and points you toward the right area to diagnose first.
