Key Features & Benefits

It’s pretty straightforward, really. The wiper arm connects the wiper motor to the wiper blade. It takes the back – and – forth motion from the motor and translates that into the sweeping motion you see across the windshield. It also provides the necessary pressure to keep the blade firmly against the glass for effective cleaning. Think of it as a key part of your visibility system. It’s part of what keeps you safe when the weather gets bad. It’s one of those things you don’t really think about until it stops working properly. It works with the wiper linkage and motor to clear rain, snow, and debris from your windshield.

Symptoms, Risks & Replacements

Without a functioning wiper arm, you’re essentially driving with severely limited vision in anything but perfect weather. It's a safety thing, plain and simple. A broken or bent arm can cause the blade to skip, streak, or not make full contact with the glass. You’ll notice if it starts leaving areas uncleared, or if the blade chatters. It’s relatively inexpensive to replace, and a good investment in your safety, and preventing more costly damage down the road. We carry a lot of these at Fixparts Online, and they’re usually pretty easy to swap out yourself, but if you're not comfortable, any good mechanic can handle it quickly.
