How to Fix Tesla Auto Wipers Not Working

The most common reason for Tesla auto wipers not working is a dirty or obstructed windshield rain sensor. The rain sensor is located behind the rearview mirror. If the rain sensor is dirty or blocked by debris, it may not be able to detect rain accurately. Use a clean microfiber cloth and a mild soap solution to clean the rain sensor.

I’ll never forget the time my Model Y auto wipers stopped working. It was a rainy day, and I was driving on the highway. Visibility was already reduced, and then my wipers suddenly stopped working. I had to pull over to the side of the road to figure out what was wrong. I checked the windshield rain sensor, but it was clean and unobstructed. I also checked the software, but there were no updates available. I was starting to get worried. I didn’t know how I would drive home in the rain without my wipers. I decided to try restarting my Tesla. To my surprise, that fixed the problem! The auto wipers started working again, and I could continue driving home safely.

In this article, I will discuss the common reasons why Tesla auto wipers might not be working. I will also provide solutions for each problem. I hope this article helps you get your Tesla auto wipers working again to drive safely in all weather conditions.

Tesla Auto Wipers Not Working

Tesla auto wipers are a convenient feature that can automatically turn on and off windshield wipers based on rain detection. However, Tesla auto wipers can sometimes not work properly, which can be frustrating and even dangerous in wet weather conditions.

Some of the most common reasons include:

  • Damaged or obstructed windshield rain sensor
  • Faulty wiper motor
  • Disconnected or loose wiper cables
  • Broken wiper linkage
  • Faulty wiper fuse
  • Dirty or broken wiper blades
  • Debris in the front camera
  • Clogged windshield wiper spray jets

Now, I’ll be discussing some of the solutions to these problems!

1. Damaged or obstructed windshield rain sensor

How to fix a damaged or obstructed windshield rain sensor

Solution 1: Inspect the rain sensor.

If the rain sensor is cracked or broken, it will need to be replaced. You can purchase a new rain sensor from the Tesla Service Center or from a third-party retailer.

To replace the rain sensor:

  1. Remove the rearview mirror. To do this, pry the mirror loose from the windshield with a plastic pry tool.
  2. Disconnect the electrical connector from the rain sensor.
  3. Remove the rain sensor from the windshield.
  4. Clean the windshield where the rain sensor will be mounted with a glass cleaner.
  5. Apply a small amount of adhesive to the back of the new rain sensor.
  6. Mount the new rain sensor on the windshield.
  7. Connect the electrical connector to the rain sensor.
  8. Reinstall the rearview mirror.

After replacing your rain sensor, that should fix the issue. But if you inspect your rain sensor and notice that it’s still in good condition, you might just need to do what I normally do, which is clean the sensor or remove anything obstructing it.

Solution 2: Clean the rain sensor.

If the rain sensor is dirty or obstructed, it will not be able to detect rain accurately. To clean the rain sensor, use a soft cloth and a mild soap solution. Be sure to dry the rain sensor completely before driving.

Solution 3: Remove any obstructions from the rain sensor.

If there are any leaves, dirt, or other debris blocking the rain sensor, remove them. I usually use a soft cloth or a brush to get this done.

How to fix a faulty wiper fuse

If you notice that your Tesla auto wiper isn’t working because of a faulty wiper fuse, you’ll have to replace it. I’ve never encountered this issue, but my friend Larry has. According to him, here’s how you can fix a faulty wiper fuse in your Tesla:

  1. Locate the wiper fuse box.

The wiper fuse box is located in the frunk (front trunk) of your Tesla. To open the frunk, press the button on the front of the car, next to the Tesla logo.

Replace the blown fuse with a new fuse of the same amperage. You can purchase new fuses from the Tesla Service Center or from a third-party retailer.

  1. Close the wiper fuse box and the frunk.

6. Dirty or broken wiper blades

How to fix dirty or broken wiper blades

Solution 1: Clean dirty wiper blades.

To clean dirty wiper blades, I wipe them down with a damp cloth and rubbing alcohol. I sometimes use a mild soap solution if the blades are very dirty. After cleaning the blades, I always make sure to dry the blades completely before using them again.

Solution 2: Replace broken wiper blades

If your Tesla’s wiper blades are broken, they must be replaced. You can purchase new wiper blades from the Tesla Service Center or from a third-party retailer.
