One of the main problems found in the Audi a3 version is the inability of the rear wiper to work or they suddenly stop working. Due to some reasons the rear wiper stops working, it may be due to some blockage or maybe the fuse or the motor is not working due to which the rear wiper also stops working.

Here in this topic, we will discuss how we can fix this problem if rear wipers are not working. First, we should know the reason due to which the rear wiper has stopped working and then we will deal with the problem accordingly.

Reasons Of An Audi A3 Rear Wiper Malfunctioning

  • Due to some blockage in washer jets
  • Due to burnt fuse or motor

Due To Some Blockage

If the wipers are not working first you should check that either it may be due to some blockage. If it is then, only take the plastic cover off and there are a tiny plastic component and a bolt, take them off and try to squirt the wash of the window if it works perfectly then it’s just clogged.

It may be caused due to blocked washer jets, which in turn will affect the rear wiper motor as it blows out the seals and allows the water into the motor. So, for its proper working, you should keep the washer jets clear.

To remove the blockage simply just remove the cap and then pull the twin squitter to remove the blockage. Use very fine wire to clean the two jets.

Or just take the small-cap off the rear wiper and simply clean out the hole with a pin.Reasons Of An Audi A3 Rear Wiper Malfunctioning

Alternate Solution: Remove the wiper motor by first removing 

the plastic trim covering the area (just undo the two screws within the two handles that 

can not be seen until you lean over and then pulling the trim backward. 

After unpacking the three 10 mm bolts, the motor connector, and the thin water hose,

You can quickly remove the motor by cutting the 13mm nut under the wiper arm. 

Know that, to see the 13 mm nut under the cover, you can gently remove the plastic cover.

To get the motor assembly from the tailgate, remember to wiggle the wiper arm. 

On the desk, put the wiper. Remove the electric motor from the section of the wiper where the gear is mounted. 

And, undo the 6 screws with the Torx from the wiper part. Other than a worm gear, a   gear, and an arm that pushes the wiper, you can see water, rust, and contaminated grease remaining inside. 

Using a thin grease to clean it and lubricate, and then reassemble everything.

You may need to use a wrench tool to remove the plastic trim covering.

Due To Burnt Fuse Or Motor

In this case, first, check the fuse. The fuse box may be located in the dashboard on the left side of the steering wheel or inside the bonnet. You must have the logbook of your version because the location may differ according to the model of the car.

Then just open the dashed box and take off the fuse to check whether it is burned or not.

If the fuse is burnt then simply replace it with a new one.

Lasting Of Motor

It is supposed that the wiper motor on a car would last a lifetime. Usually, due to the circumstances to which this section of a car is exposed, this would not be the case. 

The heat and humidity to which a wiper motor is subjected regularly will 

inevitably result in you having to repair it.

How To Test Rear Wiper Motor?

Disconnect the motor’s harness connector and scan for voltage. There should be the voltage coming from the load reduction relay with the ignition on. There should be the voltage from the relay with the rear wiper switch triggered. Also, check at the third 

(ground) terminal for continuity to ground.
