If your windshield wipers are not moving at all, several issues could be causing the problem. This guide will help you diagnose and potentially fix the issue, ensuring your wipers function effectively for safe driving.
Why Are My Windshield Wipers Not Moving?
When your windshield wipers don’t move, it can be due to mechanical, electrical, or environmental issues. Common causes include a blown fuse, a faulty wiper motor, or jammed wiper blades.
Common Causes of Non-Moving Windshield Wipers
-
Blown Fuse:
- The wiper system is powered by a fuse. If it blows, the wipers will stop working. Check your car’s manual for the fuse box location and replace the fuse if necessary.
-
Faulty Wiper Motor:
- The motor powers the wiper blades. If it fails, the wipers won’t move. Listen for any noise when you turn on the wipers; silence may indicate a motor issue.
-
Loose or Disconnected Linkage:
- The linkage connects the motor to the wiper arms. If it disconnects or becomes loose, the motor may run, but the wipers won’t move.
-
Jammed Wiper Blades:
- Debris or ice can jam the blades. Clear any obstructions and try moving the blades manually when the car is off.
-
Electrical Issues:
- Wiring problems or a faulty switch can prevent the wipers from receiving power.

Inspect the Fuse:
- Locate the fuse box using the car’s manual.
- Check the wiper fuse for any signs of damage.
- Replace the fuse with one of the same amperage if needed.
-
Check the Wiper Motor:
- Turn on the wipers and listen for motor sounds.
- If silent, the motor may need replacement.
-
Examine the Linkage:

- Manually move the blades to check for resistance.
-
Test Electrical Components:
