Windshield wipers are essential for road safety, especially in adverse weather conditions. When they stop working, driver visibility may be compromised, increasing the risk of accidents. This article explains the most common causes of the problem, how to identify and solve the fault safely, and provides preventive maintenance tips.
Why do windshield wipers stop working?
Improper wiper operation may be attributed to electrical, mechanical, or maintenance-related factors. Common causes include a blown fuse, faulty electric motor, problems with the control switch or relay, mechanical wear, and worn wiper blades.
When the wipers make noise but do not move
If the wiper motor makes noise but the arms do not move, the problem is in the transmission mechanism. Loose rods, broken linkages, or lack of lubrication may be the causes.
Problems with the wiper blades
Worn or damaged wiper blades reduce cleaning efficiency and can scratch the glass. Replace them regularly to ensure proper visibility and prevent windshield damage.
The role of the fuse
The fuse protects the system's electrical circuit. A blown fuse can cause wiper failures. Consult the vehicle manual to locate and replace the fuse with the correct amperage.
Step-by-step guide to solving the problem
Check the fuse, test the electric motor, inspect the rods and linkages, clean the wiper blades, check the washer system, and consult a professional if the problem persists.
Steps to solve the problem
Practical guide to identifying and solving windshield wiper failures.
-
1
Check the fuse
Consult the vehicle manual to locate the fuse corresponding to the system. Replace it if it is blown.
-
2
Test the electric motor
Operate the wipers and listen for noise. If there is no sound, the motor may be faulty.
-
3
Inspect the mechanism
Check the rods, linkages, and lubrication. Replace damaged or worn components.
-
4
Clean the wiper blades
Remove dust or grease residue that may affect cleaning. Replace worn wiper blades.
-
5
Consult a professional
If the problem persists, seek a specialized repair shop for diagnosis and repair.
Common causes of windshield wipers not working
| Cause | Symptom | Action |
|---|---|---|
| Blown fuse | Complete silence | Replace the fuse with the correct amperage |
| Faulty electric motor | Noise without movement | Check and replace the motor |
| Mechanical problems | Irregular movement | Inspect rods and linkages |
| Worn wiper blades | Reduced efficiency | Replace wiper blades regularly |
| Lack of lubrication | Resistance to movement | Lubricate mechanical components |
Important Tips
Replace the wiper blades regularly to ensure efficiency and prevent damage to the glass.
Avoid operating the wipers on dry glass to extend system life.
Keep the washer reservoir filled to prevent system failures.
Check wiper operation before long trips.
Do not use higher-amperage fuses, as this can damage the electrical circuit.
Frequently asked questions
Quick answers to common questions.
Why do windshield wipers stop working?
The problem may be caused by a blown fuse, faulty electric motor, failures in the control switch, mechanical wear, or worn wiper blades.
What should I do when the wipers make noise but do not move?
Check the rods, linkages, and system lubrication. Mechanical problems such as loose rods or seized linkages may be the cause.
When should I replace the wiper blades?
Replace them when they show dryness, cracks, or when cleaning becomes inefficient even with the system working.
Is it safe to drive without working windshield wipers?
No. Compromised visibility increases the risk of accidents. Stop in a safe place and seek technical assistance.
