What is a windshield wiper linkage?
The windshield wiper linkage is a key component to your wiper system as it helps to move your wipers via the control module. Without a properly working wiper linkage, your wiper blades can’t move in a synchronized manner, and eventually, your blades will stop working.
When should I replace the windshield wiper linkage on my car?
Windshield wiper linkages should be replaced if you experience any of the following symptoms:
Out of sequence blades: Your linkages are the main reason your blades can operate in sync—and if they’re not, it might be time to inspect your linkages. With a faulty linkage, your blades won’t be able to effectively clear the water, dirt, and snow that hit your windshield, thus reducing your visibility.
Sputtering blades: Worn out linkages can cause your wiper blades to ‘sputter’ or jump, rather than glide across the windshield, resulting in low visibility or a scratched windshield.
Inoperable wiper blades: Sometimes the opposite happens—your blades don’t move at all. While this can be the result of a broken linkage, it could be the sign of a deeper motor issue. Either way, it’s best to inspect your windshield wipers as soon as possible.
Grinding noise: Grinding noise can mean that the blade arm is too tight on the wiper linkage, making the gears in the wiper motor grind. If unchecked, it can cause your car’s wiper motor to burn out.
How often should a windshield wiper linkage be replaced?
Wiper linkages are designed to last the lifetime of your vehicle. However, there are factors that can cause premature damage, including climate change, a build-up of snow, or overuse. If you suspect that your windshield wiper linkage is faulty or damaged, it’s recommended to have it inspected by a nearby mechanic.
Can I replace the windshield wiper linkage myself?
Yes—if you’re confident in your DIY skills and car repair knowledge. This is a rather large task that requires a mid- to intermediate level of car maintenance and repair. If you’re unsure of which steps to take, it’s best to call a mechanic for additional help.
