Common Issues with the Toyota Windshield Wiper Arm
The windshield wiper blade and wiper arm work hand in hand to give you a clearer view of the road ahead. Designed to hold a squeegee, the Toyota windshield wiper arm connects to the windshield wiper blade, helping it wipe dirt, water, or any form of liquid off your windshield. Your vehicle's windshield wiper arm will guide you through tough weather conditions like heavy rain, snow, and fog. But since these wiper arms are exposed to the elements and ever-changing road conditions, they are prone to wear and damage. If you experience this, it's time to do some troubleshooting. Here are the common problems encountered with windshield wiper arms and the possible factors behind them:
Non-working windshield wipers
When your Toyota's windshield wiper arms aren't working after switching them on, it's recommended that you check the fuses, which usually control the different electrical functions inside your car. Blown or busted fuses are a common problem encountered by drivers. Fortunately, there are fuse testers that will help you pinpoint which fuse is blown. Replace all non-working fuses and check if the windshield wiper arms are working. If not, you might need to replace your vehicle's windshield wiper motor.
Only one windshield wiper arm is working
Unless your car is designed to only have a single and wide windshield wiper, the other windshield wiper arm's linkage is broken is if only one arm is working. Check the linkage for any sign of damage or wear since, by design, windshield wiper arms are connected to the motor by a linkage. If the linkage is worn out or broken, buy a new linkage for your windshield wiper arm and attach it.
Windshield wiper arm not clearing properly
Your Toyota's windshield wiper blade looks fine but why isn't it clearing the windshield properly? It may be baffling or confusing, but the problem lies with your loose wiper arm. All you need to do is to check the windshield wiper arm's nut and secure it. If the nut lost its thread, buy a new one and secure it properly. Just make sure to apply the correct amount of torque to avoid cracking the nut or damaging the wiper arm's fastener.
