Tesla Model 3 Auto Wipers Not Working

Tesla Model 3 Auto Wipers Not Working

Tesla cars come with auto wipers that need special care as they are a delicate part of the vehicle.

Tesla Model 3 auto wipers do not work due to their breakage, damaged fuse, and faulty wiper relay. In addition, obstructed washer nozzle, loose pivot nuts, malfunctioning blades, struck wipers, and scratching noise is reasons for their failure. You can address these issues by cleaning the windshield and blades with a good quality screen washer, tightening the pivot nuts, placing a misplaced metal tab on its position, and replacing the relay.

You can easily repair the problem once you have clearly understood the real cause of this issue.

Broken windshield wipers

These are covered with a soft rubber material that ensures their smooth movement. Sometimes you see cracks and breakage in this fragile covering, making it hard to move.

The reason may be the accumulation of debris and dirt particles. Using low-quality windshield wiper fluid in Tesla Model 3 also contributes to this issue because its chemicals badly damage the blades. In addition, they can damage the glass surface by creating scratches on it. 

Damaged fuse

You notice a damaged fuse when you switch on the button to start the wipers working, but they do not move. 

Sometimes their fuse burns due to an overload of big ice crystals or dirt particles.

They do not work due to the motor’s failure of the power supply. Low charging and overcharging of the Tesla cars also contribute to the damage of auto wipers by damaging the fuse.

Bad wiper relay

Sometimes these do not move due to a faulty wiper relay that controls its operation. You notice this issue when you select a specific speed, but they are not moving according to this speed. 

The motor can overheat and break if you do not address this issue. Purchase the new relay compatible with your vehicle in around $40 to $300 and immediately replace it.

Malfunctioning wipers blades

Sometimes your vehicle’s auto wipers are not compatible or designed to face extreme weather changes. For example, some of them can withstand lighter snowfall and ice particles, and some cannot do so. 

These will bend or break if you try to clean the heavy and sticky ice chunks with these wipers.

Always remove big ice particles from the screen before engaging its switch. Use their premium quality for better performance if you are living in a snowy climate. 

Struck wipers

This problem occurs due to the disposition of the metal tab present in the transmission system. Sometimes the arm moves upward but does not bend downward when you switch the wiper button. 

It is convenient for you to bring the tab to its original place once you successfully find this. You can easily bring the tab to its place using a screwdriver and hammer. 

Scratching noise

You hear continuous scratching noise when wipers start to move on the Tesla windshield.

The problem is due to some fault in its connection system. Small sand and salt particles on the windscreen are the main reason for this chattering sound. 

You will hear chattering sounds when you turn them on, and they touch such dirt particles on the windshield.

Thoroughly wash your front screen with a soft duster and soapy water to avoid this problem. Another reason for this problem is petroleum jelly softening the blades. 

Apply it and leave it for 10 to 20 minutes, then lower the arm for softness. You should try to fix this problem as soon as possible because these irritating sounds can distract your focus from driving. 

Loose pivot nuts

The most common issue the Tesla Model 3 owners face is loose pivot nuts. For example, you switch these on but notice the wiper arms are falling against the speed you set. 

It is because the pivot nuts core components in the linkage system are not tight.

However, you can quickly tighten this by placing the socket onto the rachet and gently applying pressure to rotate. Keep rotating until you achieve its desired level of tightness. 

Obstructed washer nozzle

The washer nozzle is responsible for spraying the water onto the screen and is essential to the windscreen washing system. Sometimes you hear the slight pumping voice but no fluid on the screen. 

It is because it gets clogged by grease and polish when you clean the screen with any chemical.

The easiest way to open up the obstructed nozzle is to use a pin. Clean the opening with the pin and blow the compressed air to apply pressure on the debris to move backward 

Defected motor

The defective motor is another reason for the low performance of your auto wipers. This is caused by a loose wire that connects its motor.

You will not hear any sound on engaging its switch if your vehicle’s motor is defective.

This is because you must immediately replace the motor after its failure. But you will hear the struggling noise if there is some defect in the engine. 

Try to fix this problem as early as possible to avoid any serious issues in your vehicle. 

Leakage of water in both directions

Sometimes you switch on the wiper button but notice water smearing from both sides of the nozzle. This problem is mainly due to dirt accumulated on the windshield and blades. 

Clean the Tesla car screen with a soft duster to remove all big dust particles. Mix some detergent into lukewarm water and pour it onto the screen.

Next, soak a microfiber fabric in rubbing alcohol and gently clean the windshield with this cloth. 

This unwanted leakage also occurs below-freezing temperatures because the low temperature will freeze the water.

Its nozzle becomes cracked and sometimes broken due to this frozen water and starts to leak water from both sides of the wiper.
