Toyota Corolla Windshield Wiper Arm Troubleshooting
Making sure you have a problem-free Toyota Corolla windshield wiper arm can guarantee safer driving. Here are some wiper arm troubleshooting tips to live by.
Loose wiper arms
It's pretty easy to spot a loose wiper arm by its performance. If it doesn't wipe your windshield very well, but the wiper blade seems fine, then you should check the nut at the base of the wiper arm. This small nut helps keep your wiper arm securely in place. When this comes loose, your wiper won't perform as efficiently, and it could even become more damaged. Luckily, you won't have to replace your wiper arm when this happens; you just need to replace the nut or tighten it.
One arm is broken
When only one wiper arm functions properly while the other refuses to move, then you likely have a linkage problem. Open up the hood and remove the windshield wiper arms. You'll then see a small grille; under this is the linkage that attaches the motor to the arms. If the linkage has come off one arm, then that explains your problem. You'll have to replace your linkage with a new one and attach the wiper arms to it.
Busted fuses can be the root cause of non-responsive wipers. To check the wiper fuse, locate the fuse box. The location of the fuse box may vary, however, depending on vehicle make and model, so be sure to check the owner's manual for help. Us the fuse pullers to remove the wiper fuse; check it if it's still intact. If it's busted, then have it replaced. If it's still in good condition, then return it and test the wipers if they work. Be sure to practice proper safety precautions before getting started.
If your wiper arms are bent, then they won't operate properly or clear your windshield properly. This damage can be cause by stray branches or improper use of the wiper arms. In any case, your best bet to remedy the problem is to try and straighten out the bent wiper arm. This might not always be doable, and even when it is, the wiper arm still won't perform as well. You'd be better off replacing the faulty wiper arms with new ones.< /p>
