It can be dangerous, especially in rainy, misty, or snowy weather, when a vehicle’s windshield wiper is not working because a defective windshield wiper will affect the driver’s visibility. A car’s windshield wiper, usually under the cowl, is connected to the car’s control module, which operates the wiper relay that then powers the electric wiper motor. When the motor is powered, it activates a linkage that moves the wiper arms back and forth.
In a Toyota Corolla, if the windshield wipers aren’t working, it could be due to a blown fuse. The wiper system’s fuse might have failed, disrupting power to the wipers. To fix this, locate the fuse box, often found under the dashboard or in the engine compartment. Check the wiper system’s fuse and replace it if it’s blown. This simple replacement can often restore functionality to the windshield wipers.
Another possible cause is a malfunctioning wiper motor. The motor powers the wipers and, if it’s faulty, the wipers won’t work. Diagnosing a wiper motor issue typically requires a bit of technical knowledge. If you suspect the motor is the problem, it’s often best to consult a professional mechanic. They can test the motor’s connectivity and functionality, and replace it if necessary.
Please keep reading to find out the possible causes of why your Toyota Corolla windshield wiper is not working and how to fix them.
Toyota Corolla Windshield Wiper Not Working
There can be many reasons why your windshield wiper is not working. If the wiper blades are torn, then the wiper cannot properly connect with the windshield to clear moisture or debris off, and additional dirt can get trapped in the torn area, causing your windshield to scratch. It would help if you replaced the torn wiper blades as soon as you notice them.
Your windshield wiper will stop working if the wiper motor has failed, which means it has lost the power source that runs it. A damaged wiper motor means that your wiper cannot clear rain, snow, or dirt off your windshield. It would be best if you replaced your wiper.
Ice or snow on your windshield can also cause your windshield wiper to stop working. Wet snow can be heavy and causes your blades to bend or your wiper arms to skip or strip at the pivots, which eventually damages your wiper blades. To avoid this problem, always remove snow from your windshield before operating your wiper blades.
Don’t forget to check the nuts that hold a wiper. If the nut is loose, the wiper arm becomes loose, too, and thus will cause the wiper not to work. To fix the problem, you need to properly reposition the loose wiper arm and tighten the wiper arm nuts.
Toyota Corolla Windshield Wiper Won’t Turn Off
You usually only use your windshield wiper when you need to keep your front mirror clear from natural elements, but what if your windshield wiper won’t turn off? You should not let your windshield wiper operate when not necessary because if your wiper system does not have any water for lubrication, the wiper’s dryness will cause extra friction. Too much friction will result in both the wiper and the motor that operates it wearing down.
If your Toyota Corolla windshield wiper doesn’t turn off, check your car alternator and your battery. These two components keep your car windshield wiper running. Your windshield wiper needs a power source to run, so if it’s not running, there’s probably a fuse in the power system, linkage assembly, and the small motor that the arms are connected to, which allows them to move back and forth across the windshield.
Check your wiring because perhaps your windshield wiper is not connected correctly anymore, hence failure to receive the signal to turn off. Maybe the relay, which is the internal electric switch mechanism inside your windshield assembly, has deteriorated. A damaged relay will either shut down your wiper or fail to turn the wiper off even when you no longer need it.
It’s also possible that the wiper stalk (that controls your windshield wiper) on the side of your steering wheel is broken. When the stalk breaks, it cannot send the signal to turn off to your windshield wiper; thus, you may need to get a wiper stalk replacement. Here’s a video to give you an idea of how to repair yours:
Toyota Corolla Windshield Wiper Fluid Not Working
It’s essential to have your Toyota Corolla windshield wiper fluid always available as it helps you clean your windshield while driving. However, sometimes a windshield wiper fluid doesn’t want to work. When your windshield wiper fluid is not working, your windshield wiper’s nozzle is probably clogged, the hose might be broken, maybe the washer pump is already bad, or there’s simply no fluid at all.
Check your washer nozzles for any clogging. If you don’t use your windshield washing system often, over time, it can get clogged. You should clean the nozzles or replace them cheaply, if necessary.
Old age or excessive use can also cause your windshield wiper’s hose to get worn out. Freezing washer fluid can also cause the hose to disconnect from the washer pump. You can determine where your hose is broken by running your windshield washer pump for 20 seconds and see where the fluid is running.
Another possible reason why your Toyota Corolla’s windshield wiper is not working is that you have a lousy washer pump that’s worn out. You’ll know that your washer pump is bad when no washer liquid comes out of your car. In this case, you’ll need to replace it.
Perhaps you should also check first if there’s any washer fluid in your vehicle. Sometimes people don’t realize that they’ve run out of washer fluid because cars don’t have any warning light to let them know this. You can get washer fluid at your nearest local stores, and once you have it, keeping them in your car would come in handy.
Toyota Corolla Windshield Wiper Fuse
Your Toyota Corolla windshield wiper might not be working because the motor has gone wrong. When the motor is bad, it will cause a blown wiper fuse. The fuse is essential as it protects the wiper motor.
The fuse blows so that the motor does not spoil when your windshield wiper motor is overwhelmed. This process is intentional. Before you replace the bad fuse, you should always check the connections first to see if the fuse affects the wiper motor.
Do read your owner’s manual to locate your fuses and help you identify which fuse protects the wiper motor. Pull out the fuse once you have found it and check it. If the fuse is blown, you will see a broken wire inside of it.
Toyota Corolla Wiper Motor Not Working
Your wiper motor is what operates the blade arms of your wiper system. When you activate your wiper, you send a signal to the wiper motors. The wiper motors move the blade arms of your wiper system back in a back and forth movement, clearing water or dirt off your windscreen.
However, your wiper motor can stop working if the wiper motor fuse burns out. A fuse happens when the motor is overloaded; heavy snow, for example, can cause a wiper blade or arm to get snagged together; hence a blown fuse. To solve the problem, remove the problem (the snow) and replace the fuse.
When replacing your Toyota Corolla windshield wiper motor, make sure you remove the cowl and plug harness to the motor. Disconnect the wiper transmission assembly. Then remove the bolts that hold the motor transmission assembly.
When you’re replacing your windshield wiper motor, never turn on the wipers if the wiper blades are frozen to the windshield or when snow or ice blocks it. After you have replaced your wiper motor, lubricate the linkages in your wiper system. Remember that you should always change the rubber inserts in the wiper arm to ensure that you can comfortably drive in any weather.
