Car owners Skoda Fabia The second generation often face the problem of failure of the rear windshield wiper. This detail seems insignificant, but its absence is critical for safety when driving off-road, in rain or in winter, when the rear window quickly becomes covered with dirt and snow. Repairing or replacing the mechanism requires an understanding of the assembly design, as standard methods for other brands may not be suitable here due to specific fastening and electric drive.
The most frequent complaints are that wiper motor stops rotating, and the lever remains stationary, or the brush itself begins to "jump" and leave unwashed stripes. In some cases, the problem lies not in the electrician, but in the mechanical part - jamming the shaft due to corrosion or deformation of the lever. We will analyze all the nuances of diagnostics and troubleshooting to return the car to full functionality.
Design features of the node on Fabia 2
The back janitor on the model Skoda Fabia The second generation (the 5J body code) has its own unique features that distinguish it from its predecessor or competitors. The motor of the drive mechanism is located directly under the plastic decorative lining, which covers the trunk hatch. This solution preserves the aesthetics of the rear door, but makes it difficult to access parts when repairs are needed.
Mounting the lever is carried out through a special slit shaft, which rotates using a worm transmission inside the gearbox. It is important to understand that janitor This model does not have a universal attachment of the type of "hook", as in the front wipers. It is fixed with a nut and a washer, which requires accuracy during dismantling, so as not to damage the paintwork or the glass itself.
Windshield wiper brush for Skoda Fabia It is 380 mm (15 inches) long and uses a specific adapter that often comes bundled with original consumables. Using cheap analogues without the right adapter can lead to poor adherence of the rubber band to the curvature of the glass, which will reduce the cleaning efficiency. The original rubber band It has high frost resistance, which is especially important for Russian climatic conditions.
Diagnosis of faults and search for causes
Before running to the store for a new engine, it is worth a thorough diagnosis, since the cause of a idle janitor can be banal. Often, owners are faced with a situation where when the mode is turned on, a characteristic click is heard, but the lever does not move. This indicates a mechanical lock or breakage of the slime on the shaft.
If the motor does not give signs of life at all (no sound), it is necessary to check the supply of voltage. This will require a multimeter and access to the engine connector. Electric circuit can be broken due to oxidation of contacts in the connector or a break in the corrugated wire connecting the body and the trunk door. These wires are often broken due to the constant openings and closures of the lid.
- 🔍 Check the availability of power on the motor connector with the washing mode on.
- 🔧 Examine the rubber corrugated for fractures lived inside the insulation.
- ⚙️ Try to manually turn the shaft of the janitor - if it does not move, the problem is in the mechanics.
Another common cause is the oxidation of the contacts of the motor itself. Over time, moisture penetrates into the body, causing corrosion of the collector brushes or windings. In such cases rear wiper motor It can be interrupted or completely out of order, requiring replacement.
⚠️ Warning: Do not try to forcibly (force) rotate the wiper lever with the ignition turned on and the washer active mode. This can instantly burn the motor or break the plastic gears inside the gearbox.
Removal and replacement of wiper brush
Replacing a brush is the simplest procedure any owner can handle. Skoda Fabia on their own. But even here there are nuances. First, you need to raise the lever of the wiper in a vertical position, taking it away from the glass. Be careful not to drop the lever on the glass as this can lead to a crack.
You need to remove the old brush. Nana Fabia The second generation uses a fixation mechanism that requires pressing on a special fixator. Pull the brush down, unfasten it from the lever and replace it with a new one. Make sure the new tires band is fully latched in the holder.
- 🛠️ Use only 380mm long brushes for the rear window.
- 💧 Check the integrity of the rubber cloth on the new brush before installation.
- 🔒 Make sure that the brush lock is securely fixed and does not dangle.
If after replacing the brush, the wiper still works poorly, it may be the lever itself that is the problem. He could bend or lose the correct angle of attack to the glass. In this case, you will need to adjust or replace the lever entirely. Angle adjustment It should be done with great care so as not to deform the metal.
- The engine is not working.
- Brushing badly.
- The lever jammed.
- The janitor makes noise
Repair and replacement of motor machinery
If the diagnosis showed that the problem in the engine, it will have to be removed. To do this, you need to remove the plastic lining in the trunk. It is usually held on several latches and screws. Carefully tuck the plastic and remove it to access the motor fastener.
The motor is attached to three nuts or bolts that need to be unscrewed. Then disconnect the electrical connector and remove the mechanism. Pay attention to the location of the sealing gum - it is better to replace it or thoroughly clean it of dirt to avoid moisture entering the cabin.
☑️ Preparing to replace the motor
When installing a new motor it's important to center. The shaft of the new device should perfectly coincide with the hole in the body. Tighten the fastener evenly so as not to skew the body. After assembly, be sure to check the operation of the wiper in the “cleaning” and “washing” mode, making sure that it does not hit the glass and does not get stuck at the extreme points.
What if the engine is running but the janitor is not moving?
If the motor is buzzing, but the lever is in place, then the slits on the shaft have been cut off or the plastic gear inside the gearbox has broken. In this case, either a complete replacement of the engine, or an attempt to repair the gearbox (complex and short-lived) will help.
In some cases, you can try to restore the old engine. If the problem is in the jamming of the bearing of the shaft, it can be lubricated. However, if the wear of the collector brushes or the winding break, repairs will be economically inexpedient compared to buying a new unit.
Specifications and Compatibility
For the correct selection of spare parts, you need to know the exact characteristics of your car. Skoda Fabia The second generation was produced from 2007 to 2014, and during this time there could be minor changes in the configuration. Below is a table with the main data for selection.
| Parameter | Meaning | Note |
|---|---|---|
| Brush length | 380 mm | Universal size for Fabia II |
| Mounting type | Specific adapter | A universal hook is not suitable |
| Part number (motor) | 5K0 955 119 | Original article (example) |
| Voltage | 12V | Standard voltage on-board network |
When buying analogues, pay attention to the brand. Original details Skoda Always have a perfect fit and durable materials. There are also good substitutes for manufacturers. Valeo or Densowhich are often placed on the conveyor. The main thing is to check the compatibility of the VIN code before buying.
Using a non-original brush without the right adapter is the main reason for the rapid wear of the mechanism and poor glass cleaning on the Fabia II.
Prevention and care of the mechanism
To the rear janitor served for a long time, regular care is necessary. In winter, before turning on the wiper, be sure to clean the glass from frozen ice. An attempt to clean the ice with a working wiper often leads to engine burnout or gear failure.
Regularly clean the brush rubber from dust and dirt. For this, you can use a wet cloth or a special rubber cleaner. Also keep an eye on the condition. windshield washer. If the nozzle is clogged, water will not get on the glass, and dry friction will quickly spoil the rubber band.
- ❄️ In winter, warm the wiper with a hair dryer or hot water before use.
- 🧼 Wash the back window and brush gum every two weeks.
- 🛑 Do not turn on the wiper on dry dirty glass.
Pay special attention to the tightness of the engine seal. If water penetrates the trunk through the janitor installation site, this can lead to corrosion of the body and oxidation of the wiring. Periodically inspect the place of attachment for cracks in the sealant.
⚠️ Warning: In winter, if a janitor is stuck to a glass, never try to tear it off by force. This can lead to deformation of the lever or breakage of the gears inside the motor.
Frequent maintenance errors
Many owners make the mistake of trying to lubricate the shaft of the janitor with a thick lubricant such as Litol or Solidol. This is a gross mistake, since the thick lubricant freezes in winter and blocks the rotation of the shaft, which leads to the combustion of the engine. Use only special silicone lubricants or liquid oils designed for low temperatures.
Another common problem is the wrong installation of the brush. If the brush is set at the wrong angle, it will leave stripes and wear out quickly. Make sure it fits evenly on the glass along the entire length. Right angle of attack - the pledge of clean glass and long service mechanism.
Don't ignore the outside sounds. If the janitor starts creaking or knocking, this is the first sign of a problem. Either the rubber band was worn, or a backlash appeared in the mechanism. Timely diagnosis will avoid expensive repairs.
Before winter, be sure to check the work of the janitor in a warm garage. If the motor is working with difficulty, it is better to replace it in advance than to be left without it in a blizzard.
