The windshield wipers help to clear away rain, snow, or any other debris that might be on the windshield. This can help improve the visibility as you drive. Part of making sure the wipers are able to work efficiently is also make sure the wiper fluid is in good condition.
Make sure to fill the wiper fluid reservoir so you will have it when you need to use the washer fluid. Doing this before any long trip you may take can help to ensure you will have enough. The wiper fluid also helps to wash away any debris or grime that may be on the windshield. The wipers should be checked regularly and replaced at least twice a year.
If you notice the windshield wipers smearing water in both directions, it may mean the wipers have worn. It may also indicate a dirty windshield with not enough water to clear it away effectively. You can use the washer fluid to clean the windshield and have the wipers clear it away. If smear marks still remain there, the wipers should be replaced as new blades can clear the windshield efficiently for you.
Another sign that the wipers need replacing is if you notice water that does not wipe away. The residue and grime that builds up on the windshield will cause water beads to stick to it. Cleaning the windshield thoroughly can help prevent this issue. If you hear the wipers vibrating or chatting against the windshield, it means that water is not getting wiped away efficiently. There could be an issue with a bent wiper arm, which makes the connection to the windshield less effective. The blade arms should be parallel to the glass. No matter what issue you notice from the windshield wipers, make sure to bring the vehicle in so we can inspect the wipers for you.
