The summertime is notorious for sudden, violent thunderstorms. When buckets of water are beating against your windshield, you need wipers that really work. Even more so at night, when a rain storm can decrease visibility to 15 or 20 feet in front of your vehicle.

Winter can be tough on windshield wipers. Ice, snow, salt and extreme temperatures make cracks and tears in the rubber that lower the effectiveness of the wipers. If your wipers are leaving visible streaks or take several passes to clear away light rain, they need to be replaced.

When replacing a wiper blade, it's better to replace the whole blade, not just the rubber part . Go to an auto parts store and they'll be able to give you the right blades for your make, model and year. If you've never replaced wiper blades before, it can be a little tricky. Just take your time, read the instructions carefully and everything should work out. It's also a good idea to observe the way your original wiper blades were attached. This may prove more valuable than anything printed on the new wiper blade box.
