Replacement of windshield wiper brushes on cars Skoda Octavia A5 It often causes difficulties for owners who do not have experience in such manipulations. The problem lies in the design feature: with a normal ignition switch off, the levers remain in the lower position, completely blocking the view and preventing access to the fastening mechanisms. Without a special technique, it becomes almost impossible to dismantle old elements or clean the windshield from ice.
There is a proven algorithm of actions that allows you to move the wipers to a vertical position, known as service position. This procedure does not require complex diagnostic equipment or removal of terminals from the battery, which saves time and nerves of the owner. It is important to observe the sequence of button pressing and working with the system Start/StopSo that the mechanism works properly.
Why is service mode needed and when is it required?
Service position is not just a convenient function, but a necessary measure in the performance of scheduled maintenance. In this state, the wiper levers rise upwards, moving away from the glass, which allows you to safely replace worn-out ones. wiper blades Or rubber inserts.
In addition to replacing consumables, the mode is necessary when performing body repairs, when a complete cleaning of the glass or application of protective compositions is required. If you leave the levers in the usual position, the risk of their breakage when driving a car or when trying to manually bend them without unlocking the electronics increases significantly.
Many owners Octavia A5 They are faced with the problem of freezing of wipers in winter. On frosty days, rubber seals are fastened to the glass, and an attempt to turn on cleaning can burn the motor or deform the traction. Activation of the service mode allows you to safely bend the levers, defrost the glass and check the operability of the mechanism before starting the movement.
Preparing the car for the procedure
Before starting manipulations, make sure that the car is on a flat surface and the handbrake is tightened. This will eliminate accidental movement of the machine, which can lead to injury or damage to the mechanism. Check that the windshield is clean and there are no large foreign objects on it that can interfere with the lifting of the levers.
It is important to note that on some modifications Skoda Octavia A5 with the system Keyless Access (keyless access) procedure may differ from the classic version with a mechanical key. Owners of such cars should be careful: the key should be in close proximity to the cabin for the correct operation of electronics.
It is not recommended to perform the procedure in a strong wind, since the levers raised in a vertical position can be torn off by the air flow, which will lead to their deformation or impact on the body. It is best to work in a calm environment, for example, in a garage or in a quiet parking space.
Step-by-step instructions: activating the mode
The process of transferring janitors to the service position Skoda Octavia A5 It consists of a clear sequence of actions that cannot be violated. First, turn on the ignition by pressing the button. Start/Stop or by turning the key into position ON (All lights on the dashboard will light up).
Without turning off the ignition, lower the wiper control lever down to the stop and hold it in this position for a few seconds. It is at this point that the team is initialized to lift the mechanism. After that, without releasing the lever, turn off the ignition.
Immediately after turning off the ignition, continue to hold the lever in the lower position for about two seconds. The wiper motor will work, and the levers will rise up, occupying a vertical position. Once they stand upright, you can let go of the control lever.
It is critically important to perform the action with the lever holding down immediately after the ignition is turned off, otherwise the mechanism will return to the original lower position.
☑️ Preparation for service regime
⚠️ Warning: If you release the control lever too early before the motor completes a full lift cycle, the system may not remember the command and return the wipers back. In this case, repeat the procedure again with the inclusion of ignition.
- No, everything went smoothly
- It was done with 2-3 attempts.
- I should have taken off the AKB terminal.
- It didn't work out at all
Returning the wipers to their working position
After the work on replacing brushes or cleaning glass, it is necessary to return the levers to the original position. To do this, turn on the ignition again. The mechanism will not return on its own, as it is in a blocked service mode.
Just gently lower the windshield wiper levers down with your hands. Do not put excessive effort, as with the ignition on, the mechanism is already ready for operation, and resistance will be minimal. Make sure the levers are gently lowered on the glass.
Then turn on the operation mode of the wipers (for example, turn them on and off once, or switch to periodic wipe mode). The motor will work, and the levers will automatically return to the normal lower parking position, snugly adjacent to the glass.
If, after ignition is turned on, the levers do not lower when manually pressed, this may indicate a failure in the wiper control module. In this case, try to turn off the battery for 10-15 minutes to reset the errors.
What to do if the janitors do not rise?
If the mechanism does not respond to the lever press, check the fuse F19 (or another, depending on the year of release) in the mounting unit. It is also possible that the motor wipers overheated and needs to cool.
Common errors and how to fix them
One of the most common mistakes is to try to manually bend the lever when the ignition is turned off without first activating the service. This leads to the fact that gears of the gearbox can be damaged, since they are not in a free position. The electronics block the free passage to protect the mechanism.
Sometimes owners forget to turn on the ignition before starting the procedure. Without power supply to the wiper control unit, the command will not be accepted. Make sure the system indicators on the instrument panel are illuminated before operating the lever.
On used cars, the mechanism may jam due to wear on the bushings or contamination. In such cases, the lever may not reach the desired position or may not rise all the way. It is recommended to check the condition of the rods and lubricate the hinges before the procedure.
If the system does not work correctly, try resetting via the diagnostic interface or simply disconnect the negative battery terminal for 15 minutes. This will reset the comfort unit and may resolve a software glitch.
⚠️ Attention: Never try to force the levers onto the window when the ignition is on if they are in the service position. This can lead to motor burnout or gearbox failure.
Before changing the brushes, lubricate the arm joints with silicone grease. This will extend the service life of the mechanism and ensure smooth operation in service mode.
Technical features of the Skoda Octavia A5 model
Cars Octavia A5 are equipped with two types of windshield wiper systems: standard and rain sensor systems. The presence of a rain sensor does not affect the algorithm for switching to the service position, but may affect the sensitivity of the system to pressing the lever.
Unlike newer generations, where the procedure is often automated through the on-board computer menu, A5 a physical button on the lever is used. This makes the method universal, but requires precision in timing the driver's actions.
The design of the levers Octavia A5 provides for the presence of stoppers that prevent the brushes from jumping off during normal movement. In the service position, these stoppers move, allowing you to remove the brush itself without having to unscrew the lever securing nut.
Comparison of mechanism access methods
There are two main ways to access the windshield wiper mechanism: through the service mode and by removing the battery terminal. The first method is preferable, as it saves the on-board computer settings and does not require reflashing the clock or radio.
The second method (removing the terminal) may be useful if the system does not respond to commands. However, it carries the risk of losing audio system settings and resetting engine adaptations. Use it only as a last resort.
The service mode also allows you to check the operation of the motor at different speeds without the risk of damaging the glass, since the levers are in a safe position. This is convenient for diagnostics before replacing brushes.
