Rear windshield wiper on the crossover Skoda Kodiaq It plays a critical role in providing visibility when reversing and in difficult weather conditions. Unlike front brushes, the rear cleaning mechanism often works in a more aggressive environment, collecting dirt from wheels and reagents, which requires special attention to the condition of the unit. Many owners mistakenly believe that this item does not need regular inspection until it completely fails.
Meanwhile, a good job. rear wiper directly affects the safety of maneuvering in parking lots and in dense urban flow. There may be several reasons for concern: from the banal wear of rubber tape to problems with an electric drive or lever. In this article, we will analyze in detail the nuances of the design of the unit, the criteria for the selection of original and analog spare parts, and also provide step-by-step instructions for self-service.
Design features and principle of operation of the unit
The mechanism of cleaning the rear window on the model Skoda Kodiaq It has its own unique engineering solutions that distinguish it from previous generations or other models of the VAG Group. The janitor lever is attached to the shaft of the electric motor through a special fastening, which requires accurate fixation to prevent backlashes. When the regime is in place Intermittent In the interval or constant motion, the motor receives a signal and sets the entire mechanism in motion.
Particular attention should be paid to the seals of the shaft passing through the body. Over time, they can tan or damage, which leads to moisture entering the luggage compartment. Waterproofing This is a critical aspect, as water can cause corrosion of contacts or damage the door lining. Do not underestimate the role of the correct angle of pressing the brush against the glass, which is provided by the shape of the lever.
- ๐ง Lever made of reinforced plastic with metal core for reliability
- ๐ง The sealing ring should be elastic to protect against leakage.
- ๐ The electric connector has a moisture-retarding design (IP67)
How to choose the right brush: original versus analogues
When choosing consumables, it is important to understand that the length and shape of the rear wiper attachment to the Skoda Kodiaq They're strictly regulated. Incorrectly selected size can lead to the fact that the brush will beat the glass frame or, conversely, will not close the desired area. Original parts are marked with the manufacturerโs code, which guarantees perfect compatibility with the drive mechanism.
However, the market offers many high-quality analogues that can surpass the original in terms of the life of rubber. The main condition is the conformity of the landing place. Often owners face the problem when universal adapters do not provide a tight fit, causing vibration. Aerodynamic profile The brush is also important so that at high speeds the air flow does not tear it away from the glass.
- ๐ The standard length of the back door brush is 300 mm (12 inches)
- ๐ก๏ธ Frame or frameless construction - the choice depends on climatic conditions
- ๐ท๏ธ The original has the marking Skoda / VW, analogue - specialized brands
If you are not sure about the compatibility of a particular brand, it is best to refer to directories using your vehicleโs VIN code. This will eliminate the risk of buying a part that will not fit on the mount.
Step-by-step instructions for replacing the rear wiper
The brush replacement process The ล KODA KODIAQ does not require a complicated tool and takes no more than 15 minutes with free access to the rear door. First, you need to bend the wiper lever from the glass to the characteristic snap of the fixator. Then you need to press the fixture of the brush and, slightly swaying, remove the worn element.
After removing the old part, check the status of the seat on the lever. If there is dirt or rust, clean it before installing a new brush. Insert the new element until you hear a clear click confirming the fixation. Carefully lower the lever back on the glass.
โ๏ธ Preparing to replace the brush
It is important not to make excessive efforts during dismantling, so as not to damage the plastic mechanism of the lever. Fragile latches can burst if approached incorrectly.
Before installing a new brush, wipe its rubber tape with a wet wipe to remove factory lubrication and dust.
Diagnosis of problems with the drive and motor
Sometimes the problem is not in the brush itself, but in the electric motor or drive traction. If the janitor works in jerks, stops in the wrong position or makes extraneous sounds, it is necessary to conduct an in-depth diagnosis. A common cause is jamming bushings, which wear out over time from friction on the shaft.
In some cases, it is necessary to remove the rear door trim to visually inspect the mechanism. Check to see if the attachment of the motor itself to the body is loose. Vibration during operation may cause poor contact in the power connector. Electric circuit It can also be damaged if the wiring rubs against the metal of the door.
- ๐ A knocking or grinding noise indicates wear on the plastic gears in the gearbox.
- โก Lack of movement may be due to a blown fuse
- ๐ Incomplete lever travel indicates mechanical jamming
If you hear the motor humming but the lever does not move, the problem is almost certainly a mechanical issue with the drive. In this case, replacing the motor will not help; you need to disassemble the gearbox.
What to do if the motor is running, but the lever is not in place?
It is necessary to remove the gearbox cover and check the condition of the plastic gears. If they are worn down, the entire assembly or gears need to be replaced, if individual replacement is possible.
- The brush is just worn out
- The lever dangles and plays
- The motor does not turn on
- The motor hums, but does not turn over
Restoration and replacement of rear wiper glass
In rare cases, it may be necessary to replace not only the brush, but also the glass itself if it is cracked or has deep scratches that interfere with your view. However, most often the problem lies in the deformation of the lever itself, which can bend due to an impact or careless cleaning of the ice. Lever geometry should be ideal for uniform pressure.
If you notice that the wiper leaves opaque streaks, try adjusting the clamping angle. To do this, carefully bend the lever in the desired direction, but do it very carefully so as not to break the plastic. In some cases, replacing the seal on the shaft, which loses its elasticity over time, helps.
| Problem | Probable Cause | Recommended Action |
|---|---|---|
| The janitor jumps on the glass | Dirty glass or dried rubber | Clean the glass and lubricate the rubber with silicone |
| Weak pressure | Weak lever spring | Replace the lever assembly or spring |
| Water leaks into the interior | Damaged shaft seal | Replace O-ring |
| Noise during operation | Wear of gearbox bushings | Disassemble and replace bushings or motor |
Typical mistakes of owners and how to avoid them
One of the most common mistakes is turning on the wiper when the glass is dry. This leads to instant wear of the rubber band and overheating of the motor. Using washer Be sure to do this before you start moving the brush, especially in winter. Ignoring this rule may result in the motor burning out and the brush deteriorating in one season.
Another mistake is trying to clear the ice with an ice heater or a stiff brush while the wiper is in the working position. Ice can jam the mechanism, causing the fuse to burn out or the gears to break. Always move the lever to the service position before cleaning the glass from frost.
โ ๏ธ Attention: Never turn on the rear wiper if it is frozen tightly to the glass. This is guaranteed to damage the motor.
It is also worth monitoring the condition of the washer reservoir. If it is empty, the pump may overheat when trying to supply water. Check fluid levels regularly and use special anti-freeze compounds suitable for your climate.
Regularly cleaning the glass and using washer before operating the wiper will prolong the life of both the rubber band and the electric motor.
