What is a Wiper Motor and how does it work?
Driving safely is almost impossible if you cannot see the road clearly. Windshield washers are used to clean your windshield from rain, snow, dirt, and other debris. It is an essential security element that ensures your vision is clear. Every wiper system is made specifically for your vehicle.
The wiper motor controls the forward/backward movement and direction of the windscreen wipers. The control buttons can be found on the wiper arm located on right side of the steering wheels. The switch activates the motor and sends a signal for the wipers to operate at different speeds. The switch can malfunction over time, as with other parts of your vehicle. The wiper motor is often the problem if your wipers stop working when you activate the switch.
Although it is unlikely that your wiper motor will fail, there are some signs to help you recognize the problem.
Wiper Motor Failure Symptoms
Wipers moving slower than programmed
Modern vehicles come with programmeable wipers. They can be set to operate in different stages and have different delay times. The lowest setting is for driving in drizzle. If it rains heavily, the switch will be at the highest setting. The wiper motor may have a fault if the high speed setting is selected and the wipers do not move as fast as they should. Sometimes, dirt, mud or other substances can build up in the engine’s mechanical parts. The engine’s operating speed may be affected in such cases. This problem can be caused by a malfunctioning wiper motor or other parts.
Fixed Wiper Operation at Single Speed
Another common sign is the wipers moving at the same speed, despite having changed the range. The module may send the signal to the motor, which could cause this. You should inspect the module before you replace the motor.
Wipers not moving
If the wipers do not move when you activate the switch or the motor does not run, it is likely that the motor has an electrical fault or damage. A blown fuse may sometimes cause this. A short circuit can cause the fuse to explode by causing high current. This problem should be fixed by a professional.
Wipers can sometimes quit while working
The wipers are programmed so that they clean your windshield every time you turn them on. The problem could be an electrical issue, such as your wipers stalling or getting stuck during cleaning. This can be caused by a faulty relay, short circuits or a problem with the wiper motor.
Wipers Aren’t Aligned Correctly
The wipers must remain in the correct position when you turn off your wiper switch. Most wipers will be locked to the lower windshield part. If the wipers do not move and block your view, it is usually a sign of a problem with your engine. Most likely, the motor needs to be replaced.
Humming Sounds
The wiper motor could be failing if you hear humming sounds in addition to the previously mentioned symptoms. This sounds indicates that the wiper motor may not be able to transmit the required power to the wipers. A bad wiper relay can also lead to this problem.
Bref:
- – Wipers move at a slower speed than the programmed speed
- – The wipers operate at the same speed regardless of whether the level has been changed
- Wipers are not moving
- Wipers can sometimes stop
- Wipers are not properly parked
- A hum from the wiper motor is one of the most obvious signs of wiper motor failure.
The wiper motor is usually not repairable because it is complex. It must be replaced if it fails. You should seek professional assistance if you see any of these warning signs.
Why is the Windshield Wiper Motor failing?
- – Wipers can jam or overload motor circuits due to adverse conditions, such as excessive ice and snow.
- Short circuits in cables can cause the motor’s fuse to blow out or burn.
- Water can leak into the circuits and cause malfunctions due to clogged water discharge channel.
- Over time, components inside the engine can wear out.
- – Rust, mud, etc. The wiper motor could jam or malfunction due to various factors.
