If you’re like most drivers, you probably don’t think much about your car’s wipers. But if you ever get stuck in a rainstorm or snowstorm, your car’s wipers can be a life-saver. Here’s how to turn them on in most cars: 1 Open the door and get out of the car. 2 Look for the “wiper” switch on the dashboard or inside the door. It may be labeled “washer” or “wiper on/off.” 3 Turn the switch to “on.” If it’s a manual transmission, you may need to shift into park first. 4 Close the door and wait for the wipers to start working. They should move back and forth quickly several times before stopping. ..
