Rear wiper on Ε KODA Octavia A5 It would seem a simple mechanism, but its failure can seriously impair visibility in rain or snow. Owners often face a situation where the brush suddenly stops moving, works in jerks or does not respond at all to the switch. In 80% of cases, the problem is solved without visiting the service - it is enough to know where to look for a malfunction and how to fix it.
In this article we will look at all possible reasonsWhy does the back door not work? Octavia A5 (including restyled versions of 2008-2013), from the banal burnout of the fuse to wear gears gear gear gear gear gear gears. You will learn how to check the electric circuit with a multimeter, where the fuse block for this model is located, and which ones are used. The hidden βdiseasesβ of the janitors of the Octavia A5 Not even in the official manuals. For clarity, connection schemes, photos of key nodes and video instructions are given.
1. Diagnostics: where to start if the rear wiper does not work
Before disassembling half of the machine, perform basic check - this will save time and nerves. Start with the simplest:
- π Check the fuse. On Octavia A5 The safety lock is responsible for the back wiper.
F36 (10A)in the unit under the steering wheel (left of the steering column). Take it out with forceps and inspect it for burnout. If the fuse is intact, but the wiper does not work, the problem is deeper. - π Switch test. Turn on the rear wiper and listen: can you hear the sound of the motor (buzz) from under the plastic skin of the trunk? If there is a sound, but the brush does not move, the drive mechanism is to blame. If silence is an electrical problem.
- π‘ Checking of the reversing lamp. This is no joke. Octavia A5 The rear wiper and the reversing lights are sometimes connected to the same circuit. If the lamp is not burning, look for a wire break or oxidation of contacts in the tourniquet.
If the basic test did not give a result, proceed to a deep diagnosis. At this stage, you will need multimeter (or at least a 12V control lamp) and a wiring scheme for a wiper. Please note: Octavia A5 with 1.6 MPI and 1.8 TSI The scheme may differ - check the VIN code.
- Less than a week
- 1β3 months
- More than six months
- Never worked from a purchase.
2. Fuse and relay: where to look and how to check
Fuse box on Ε KODA Octavia A5 Located to the left of the steering column β to access, pull the lever on the plastic cover. The back janitor is responsible:
- π Fuse F36 (10A) - the main protection of the chain. Burns out when short circuit or overload (for example, if the wiper is jammed with ice).
- β‘ Relay J317 - runs the motor. It is in the same block, but not always signed. Look for a marked relay.
53(there is a diagram on the block cover).
How to check:
- Remove the fuse
F36If you have a new one, then you will see the light of the light, and if you have a new one, replace it with a new one (only 10A!). - If the fuse is good, check the relay
J317. Then, change the place of the scoring (for example, the scoring). If the janitor is working, the relay is faulty. - If both the fuse and the relay are serviceable, but the wiper does not work - the problem is in the wiring or motor.
Remove the fuse F36 (10A) and examine the light
Check the J317 relay by changing it with a known worker
Examine contacts in the block for oxidation
Call the chain with a multimeter from the fuse to the motor->
Attention! On Octavia A5 with DSG The block of fuses may have a different numbering. Clarify the scheme for your configuration by manual or on the site ERWIN (registration required).
3. Rear wiper gear motor: disassembly and repair
If the fuse and relay are working, but the wiper does not move, it is to blame. gear motor It's the most vulnerable node in the system. Nana Octavia A5 It is located under the plastic skin of the trunk (on the driver's side). To get to him:
- Remove the plastic trunk trim by snapping off the clips (use a plastic spatula to avoid breaking).
- Unscrew the 3 motor mounting bolts (key on
10). - Disconnect the power connector and remove the mechanism.
Typical gearmotor malfunctions:
- βοΈ Gear wear β the plastic teeth wear out over time, and the wiper works jerkily or does not move at all. Solution: replacing the gears or the entire gearbox.
- π₯ Collector burning - if the motor βbuzzesβ but does not rotate, most likely the brushes or commutator are burnt out. Only replacement will help.
- π§ Corrosion β water enters the mechanism through the seals, oxidizing the contacts. Cleaning and lubricating may help temporarily.
To repair the motor you will need:
- π§ Set of screwdrivers (phillips and flat).
- π§΄ Lubrication
LIQUI MOLY Silicon-Fett(for plastic gears). - π A magnifying glass or flashlight for inspecting the collector.
How to check the motor without removing it
Connect the 12V battery to the motor connector (plus to pin 1, minus to pin 2). If the wiper moves, there is a problem with the wiring or switch. If not, the motor is faulty.
Attention! On Octavia A5 with 4Motion The rear wiper motor may have a different marking (for example, 1K6 955 119 C instead of 1K6 955 119). Check the article number before purchasing a spare part!
4. Wiring and contacts: where to look for breaks
If the motor is working, but the wiper does not work, the problem is wiring. On Octavia A5 most often suffer:
- π Motor connector β contacts oxidize or come off. Check if the chip on the motor is loose.
- π Corrugated wiring harness β rubs against the body at the transition from the trunk to the rear door. Inspect the wires for chafing.
- π Weight - on Octavia A5 The βgroundβ of the rear wiper is mounted under the plastic lining of the trunk (bolt on
10). Oxidation is a common cause of failure here.
How to ring a chain:
- Disconnect the motor connector.
- Set the multimeter to resistance test mode (
200 Ohm). - Ring the wires from the connector to the fuse box. The resistance should be close to
0 ohm(break -1on the screen).
| Chain section | Normal resistance | Cause of malfunction |
|---|---|---|
| From fuse F36 to relay J317 | 0β0.5 Ohm | Broken or oxidized contacts |
| From relay J317 to motor connector | 0β1 Ohm | Frayed wire in corrugation |
| Motor ground (black wire) | 0β0.3 Ohm | Oxidation of the mass attachment point |
A critical feature of the Octavia A5: the rear wiper wires pass through the rubber seal between the trunk and the rear door. Over time, the rubber hardens and the wires rub against the metal. Inspect this area carefully!
5. Switch and control unit: hidden problems
If all elements of the circuit are in good working order, but the wiper does not respond to the lever, the fault is switch (steering wheel paddle shifter) or comfort block (J393). On Octavia A5 The rear wiper switch often fails due to:
- π¦ Ingress of moisture (for example, after washing).
- π₯ Burnt contacts inside the switch.
- π Wear of plastic guides.
How to check the switch:
- Remove the plastic trim under the steering wheel (unscrew 2 Torx screws
T20). - Disconnect the switch connector (chip
Xon the diagram). - Ring the contacts with a multimeter in the mode
diode. When the rear wiper is turned on, a beep should sound.
If the switch is OK but the wiper does not work, the problem may be comfort block (J393). This unit controls all the βlittle thingsβ - from wipers to heated seats. On Octavia A5 it is located behind the dashboard (driver's side). It can only be diagnosed with a scanner (VCDS or OBDeleven). Typical mistakes:
01330 β Central Control Module for Comfort System (J393)β block malfunction.01331 β Door Control Module; Rear Left (J388)β problem with the wiring to the rear door.
If you don't have a scanner, try resetting the errors by disconnecting the battery for 10 minutes. Sometimes this helps with βglitchesβ of the comfort unit.
6. Mechanical faults: lever, rod, brush
If the motor hums but the brush does not move, the problem is mechanical part. On Octavia A5 Most often they break:
- 𦴠Drive traction β a plastic rod connecting the motor to the wiper lever. Over time it will crack or break.
- βοΈ Lever joint - rusts or sours. Lubricate
WD-40and check the play. - π§Ή wiper blade - if it βsticksβ to the glass (for example, after frost), the motor may burn out from overload.
How to check the mechanics:
- Remove the plastic trunk trim.
- Turn on the rear wiper and observe the movement of the linkage. If it does not move, the problem is in the motor or drive.
- If the rod moves, but the lever does not, check the hinge joint.
Attention! On Octavia A5 with panoramic roof The rear wiper mechanism may differ - it uses an extended rod. Do not confuse spare parts when purchasing!
7. Prevention: how to extend the life of your rear wiper
To avoid problems with the rear wiper on Ε KODA Octavia A5, follow simple rules:
- π§ in winter Before parking, turn off the wiper and raise the blade - this will prevent freezing.
- π§ Washing β do not direct the stream of water directly at the motor (especially under pressure).
- π οΈ Lubrication β once a year, treat the lever hinges and rod with silicone grease.
- π Diagnostics β at the first signs of a malfunction (jerking, slowing down), check the motor gears.
If the wiper has already started acting up, donβt delay repairs. For example, wear of the gear motor gears on the Octavia A5 often leads to jamming, and this is fraught with a blown fuse or even a fire in the wiring.
Regular cleaning and lubrication of the rear wiper mechanism increases its service life by 2-3 times. Pay special attention to the seals - they protect the motor from moisture.
FAQ: Frequently asked questions about the Octavia A5 rear wiper
β Why does the rear wiper only work in one direction?
This is a typical sign wear of gear motor gears or drive rod failure. Gears can slip without transferring movement to reverse. The solution is to disassemble the motor and replace plastic parts. A temporary solution is to lubricate the gears with silicone grease, but this will not help for long.
β Can the rear wiper motor be repaired or is it just a replacement?
In most cases, the motor can be repaired. Most often they fail:
- Gears (you can buy a repair kit for ~500 rubles).
- Commutator brushes (resoldered or replaced).
- Bearings (pressing required).
A complete replacement of the motor will cost ~3000β5000 rubles, so repairs are more profitable. The exception is a burnt anchor or hull corrosion.
β Where to buy spare parts for the Octavia A5 rear wiper?
Original spare parts:
- Motor:
1K6 955 119(or1K6 955 119 Cfor 4Motion). - Drive traction:
1K6 955 615. - Repair kit gears:
1K6 955 119 REPKIT.
Analogues (30β50% cheaper): FEBI, MEYLE, TOP Ran. Buy only from trusted sellers - there are many fakes with low quality plastic on the market.
β How to remove the rear wiper if it is stuck?
If the brush is stuck to the glass:
- Water the wiper mounting area
WD-40or warm water (not boiling water!). - Gently pry the brush out with a plastic spatula, wiggling it to the sides.
- If this does not help, remove the plastic trunk lining and unscrew the nut securing the lever (the key is on
13).
β οΈ Do not use force! On Octavia A5 The wiper arm is attached to the glass through a fragile bracket - it is easy to break.
β Why does the rear wiper work by itself?
This is a sign short circuit in the circuit or comfort unit malfunction (J393). Most often the culprits are:
- Oxidized contacts in the motor connector.
- Stuck relay
J317. - Short circuit in the wiring (for example, after unsuccessful repair).
First check the motor connector - moisture often accumulates there. If this does not help, diagnostics with a scanner is required.
