Replacing windshield wiper blades on a car Skoda Octavia A7 is a procedure that many owners try to do themselves to save time and money. However, the design of the front windshield wiper in this model has its own characteristics, which often lead to errors during dismantling. Incorrect actions can cause the spring mechanism of the lever to break, or the lever itself to bend, hitting the glass.
To avoid costly repairs and damage to the windshield, you must strictly follow the algorithm of actions provided by the manufacturer. In this article we will look in detail at how to convert a car to service mode, how to correctly unfasten the brushes and what nuances should be taken into account when installing new elements on Octavia A7.
Proper replacement of brushes is the key to your safety during rain or snowfall. The effective operation of the windshield wiper directly affects the visibility of the road, so you should not neglect regular maintenance. If you notice that your wipers leave streaks, squeak, or don't adhere to the glass, it's time to take action.
Preparing the car and instruments for the procedure
Before you begin to physically impact the windshield wiper mechanisms, you need to prepare the workspace and the car itself. You won't need complicated tools, but having certain items will make the task much easier and reduce the risk of accidental paint damage.
First, make sure the car is on a level surface and the engine is turned off. Open the hood and check the condition of the windshield wiper arms: they should not have visible deformations or signs of corrosion. If you plan to change not only rubber, but also plastic adapters, prepare new elements in advance, as the old fit may be too tight.
You will definitely need a clean, soft rag or towel to place under the lever when removing the brush. This will protect the glass from being accidentally hit by the metal frame of the lever if the spring comes off. A small piece of electrical tape or masking tape will also be useful to secure the position.

Activating the service mode via the on-board computer
The most difficult stage for beginners is switching the wipers to service mode. In the normal state, the levers are in the lower position, pressed against the glass, and it is impossible to remove them without the risk of damage. The manufacturer has provided a special function that lifts them vertically, freeing access to the mount.
To do this, you need to sit behind the wheel and turn on the ignition without starting the engine. On the dashboard, press the button Menu or use the joystick on the steering wheel to enter the car settings menu. You need to find the section responsible for service functions or wiper settings.
You need to select sequentially Settings -> Service -> Wipers (or Wipers depending on the firmware version). After selecting the option Service position (or Service position) the arms will automatically rise and remain in a vertical position.
It is important not to turn off the ignition until the work is completed, otherwise the mechanism will return to its original position and pinch your fingers or break the new brushes when trying to remove them. If you accidentally turn off the ignition, you will have to repeat the activation procedure again through the menu.
β οΈ Attention: Do not try to manually remove the levers from the glass if they are not in service mode! The spring is very powerful, and if you try to bend it with your hands, you risk bending the lever itself or breaking the glass.
Removing windshield wiper blades step by step
When the levers are raised to a vertical position, you can begin to directly remove the brushes. Mounting design on Octavia A7 belongs to the type Hook (hook) or Pin (pin), depending on the year of manufacture and configuration, but most often there is a combined version with a locking button.
First you need to bend the brush away from the lever at an angle of 90 degrees. On the body of the brush you will find a plastic locking button. Press down on it and, while holding it, slide the brush down along the lever until it is released from its engagement. Act smoothly, without jerking, so as not to break the plastic mechanism.
If you have a locking pin system, you may need to lightly press the pin through the hole in the adapter body. Sometimes the fastener sticks due to dirt or ice, so clean the connection area first.
- π Bend the blade perpendicular to the wiper arm.
- π Locate and press the release button on the adapter.
- π Smoothly slide the brush down, releasing the hook of the lever.
- π§Ή Remove the old brush and set it aside.
After removing the first brush, repeat the procedure for the second. Please note that the length of the brushes is Skoda Octavia A7 may differ: the driver's side is usually longer (650 mm), and the passenger side is shorter (425 mm or 400 mm). It is difficult to confuse them, but it is better to check the labeling before purchasing.
β οΈ Caution: Hold the lever with one hand when removing the brush with the other. If the spring mechanism suddenly activates, the lever will hit the glass with great force, which is guaranteed to break the windshield.

Installing new brushes and checking functionality
Installing new elements is the reverse process of removal, but requires the same care. Take a new brush, making sure it is the right length for your side of the car. Insert the hook of the lever into the groove of the new brush adapter until you hear a characteristic click.
You need to make sure that the latch is fully engaged. Pull the brush upward to check that it is securely attached. It should not slip or dangle. If you feel play, try rearranging the adapter or replacing it with another one if it is removable.
After installing both brushes, you must return them to their working position. To do this, push the windshield wiper lever down towards the glass until it takes its normal place. Do not lower the lever suddenly to avoid damaging the rubber blade on the dirty glass.
Turn on the ignition and activate the mode Test or Parking in the menu to ensure that the levers have returned to their lowest point. If everything is done correctly, the wipers will lie flat on the glass, without distortions or gaps.

Compatibility table and brush sizes
To make it easier to select the right elements, we have prepared a table with the main parameters specific to the model Octavia A7 (2013β2020). Sizes may vary slightly depending on year and market, so always check before purchasing.
| Car side | Typical Length (mm) | Mounting type | Note |
|---|---|---|---|
| Driver's (left) | 650 mm (26 in) | Hook / Pin | Main brush, long |
| Passenger (right) | 425 mm (17 in) | Hook / Pin | Short brush |
| Rear wiper | 400 mm (16 inches) | Special clip | Specific adapter |
| Rear wiper (Sport) | 355 mm (14 in) | Special clip | For versions with other mechanism |
Correct sizing is critical for cleaning efficiency. If the brush is too long, it may touch the edge of the glass or each other, causing breakage. If itβs too short, an uncleaned area will remain, which is dangerous in the rain.
Common errors and how to fix them
Many owners make the same mistake: they try to remove the brush without putting the car into service mode. This causes the lever to hit the glass sharply when the spring is released. Repairing a windshield after such an incident costs tens of times more than new blades.
Another common problem is the plastic retainer breaking during dismantling. If you feel that the button is not being pressed, do not force it. Try warming up the plastic a little with a hairdryer or using a spray lubricant to remove dirt and ice.
It is also worth paying attention to the condition of the lever hinges. If they are frozen or rusty, movement may be difficult. In this case, you should not force the process; it is better to wait until the car warms up in a warm garage.
- β Do not use brute force when pressing the latches.
- β Do not remove the brushes without service mode.
- β Do not leave levers raised unattended for long periods of time.
- β Check the condition of the hinges before installing new brushes.
If you break the retainer, you can replace it separately without replacing the entire adapter. To do this, you will need to disassemble the plastic brush housing and rearrange the mechanism. This will save money, but will require patience and a small screwdriver.
Before winter, be sure to remove the brushes and clear the glass of ice. Ice can jam the mechanism, and the wipers can burn out or break when you first turn them on.
Additional Wiper Maintenance Tips
In order for brushes to last longer and work effectively, they need care. Wash the rubber regularly with a sponge and soapy water, removing soot, road dust and reagents. Dirt on the blade scratches the glass and reduces the quality of cleaning.
Do not turn on the wipers on dry glass. This creates a huge load on the engine and leads to rapid wear of the rubber. Always use windshield washer fluid, even in cold weather when the glass appears clean.
How to extend the life of rubber brushes?
Wipe the rubber regularly with an alcohol wipe to remove any grease film. In winter, use special heated brushes or βframeβ models that are better adapted to frost. Do not leave the brushes stuck to the glass in the cold - this will deform the rubber.
If you notice that the brushes are starting to squeak or leave streaks, try cleaning the glass first with a special degreaser. Often the problem is not in the brushes, but in the greasy film on the glass, which ordinary washing liquid does not remove.
Regular cleaning of rubber and the use of high-quality washer prolongs the life of the brushes by 30-40% and protects the glass from scratches.
