Why People are Lifting Their Windshield Wipers at Night — Let's Break It Down...

When not to do it

Strong wind. Wiper arms are pressed against the glass by a strong spring. Lifted up, they stick out into the wind, and a hard gust can slam an arm back down onto the windshield hard enough to chip or crack it. If a windy storm is forecast, leave the wipers down and use one of the tricks on the last page instead. The same goes for the morning: hold the arm and lower it gently. Never let it snap back onto the glass.

Hidden wipers. On some cars, the wipers park low, partly under the back edge of the hood. If you try to lift them there, the arm can hit the hood, scratch the paint, or bend. Check your owner's manual first. Many of these cars have a service position, a setting that moves the wipers up a few inches so you can lift them safely. If your car doesn't have one, leave the wipers down.

Never pour hot water on a frozen windshield. It is the most common winter mistake. The sudden change from freezing cold to hot can crack the glass, especially if there is already a small chip, and the water can freeze again on the glass and on the ground where you are standing. Use the defroster, a plastic scraper, and a little patience. And if your wipers are frozen down, don't yank or switch them on; let the defroster loosen them first.
