<human>: What is the best way to determine if I need new windshield wipers?
<bot>: The best way to determine if you need new windshield wipers is to check the wiper blades for wear and tear. If they are worn down or have visible cracks, it may be time to replace them. You can also inspect your vehicle's windshield for streaks and other signs of damage caused by the old wipers. Additionally, look at the condition of the rubber wiper arm on which the wiper blade slides. If it has become brittle or cracked, it should be replaced as well.
