How to Fix Your Mercedes Benz Wiper Blade
The Mercedes Benz wiper blade is undoubtedly an ingenious product that can last you years if it is maintained well. Nonetheless, it can still be susceptible to damage and deterioration if it's always exposed to external elements like sunlight, dirt, oil, ozone, and other airborne contaminants. Undue wear and tear can also cause your wiper blade to degenerate. Harsh weather can have the same effects. When it's freezing, the blade may turn brittle, causing it to crack. When it's blazing hot, the rubber in the blade can be warped, causing it to malfunction when used. When your wiper blade is no longer functioning properly, you have to repair it, since your driving safety is based on a clear view of the road. If you're up for fixing the blade yourself, here is a guide to help you get started.
Difficulty level: Easy
Things you'll need:
- Glass cleaner
- Windshield wiper fluid
- Rubbing alcohol
- Paper towels
- Clean cloth
- Glass polish
- Blade refill
- Flathead screwdriver
- Wiper arm assembly
Step 1:Clean your Mercedes Benz wiper blade thoroughly with a glass cleaner and a squeegee. Make sure to apply the glass cleaner to every side of the blade, so that all excess dirt will be removed.
Step 2:Check the windshield wiper fluid reservoir located under your hood. If it's low in or out of windshield wiper fluid, refill it using a funnel. Lubrication is necessary to give your blade a smooth performance. When it's lubricated, it can glide across the glass gently and quietly.
Step 3:If the problem with your wiper blade is hardening, you can use paper towels and rubbing alcohol to restore it. Just make sure that you wipe the blade dry when you're done.
Step 4:Using a damp, clean cloth and glass polish, rub your windshield wiper in a firm, circular motion. Do this until you have covered the entire windshield. Afterwards, rinse your windshield wiper blade with water.
Step 5:Adjust the tightness of your wiper assembly. If it's too tight or too loose, it won't function optimally. To identify the tightness of your windshield wiper, simply wriggle the arm gently and see if it moves easily or not. If it does move with little effort, you know your assembly is too loose. If it doesn't move at all, it may be too tight.
Step 6:To adjust the tightness of your wiper assembly, remove the plastic covering at the base of the wiper arm using a flathead screwdriver. When you see the nut and bolt that hold the wiper in place, use the screwdriver again to adjust the bolt. Attach the socket to the ratchet, then adjust the bolt by either tightening or loosening it, whichever applies. Keep in mind the “righty-tighty, lefty-loosey” principle when doing this step.
There may be many reasons why your Mercedes Benz wiper blade is not performing at its best. Diagnosing the root cause of the problem may take you some time, but once you've identified what's wrong, the battle is half-won. You can choose to act on your own or consult the help of a professional. Either way, it's always best to address the problem while it can still be contained.
