You've turned on the wipers on yours. ล KODA Octavia TourBut they suddenly stopped working? Or are the brushes moving in jerks and the motor is making a suspicious hum? This problem is familiar to many owners of the Czech sedan - especially on models. 2013โ€“2020 (restyled versions FL and RS not an exception). In 80% of cases, it is not mechanical breakdowns that are to blame, but electrics or wear and tear of parts that can be repaired independently.

In this article we will analyze all possible reasons - from the banal burnout of the fuse to the failure of the gearbox motor. You will learn how to check. fuse F35 (15A) per block SCMwhere is the relay located J317Why do the janitors โ€œhangโ€ upright? And also, unique life hack to restore the work of wipers without replacing the motor (suitable for Octavia Tour with a system) Rain Light Sensor).

1. Fuse and relay: first check

If the wipers are on Octavia Tour Do not respond to the switch at all (even in manual mode), start with fuse box. In 30% of cases, the problem lies in the burnt-out fuse F35 (15A) or a faulty relay J317. Both elements are located in central fuse box under the steering wheel (to the left of the pedals).

How to check:

  • ๐Ÿ”ง Fuse F35Remove it with tweezers and examine for breaking thread. If the fuse is intact, but the wipers do not work, the problem is deeper.
  • โšก Relay J317: swap it with a similar relay (e.g., J100 for the stove fan. If the wipers are working, the relay is a replacement.
  • ๐Ÿ” Oxidation of contacts: even if the fuse is intact, clean the nests of the block from corrosion (use WD-40 or alcohol).

On Octavia Tour with Rain Light Sensor (Rain sensor) also check the fuse F41 (5A) - it is responsible for powering the sensor. If it burns out, automatic wipers wonโ€™t work, but manual mode can work.

โš ๏ธ AttentionNever replace the F35 fuse with a more powerful one (e.g. 20A instead of 15A). This could lead to wiring fire in the block SCM (comfort module).
๐Ÿ“Š What's your Octavia Tour like?
  • Until 2013 (pre-facelift)
  • 2013โ€“2017 (FL restyle)
  • 2017โ€“2020 (after facelift)
  • I don't know

2. Motor-reducter wipers: symptoms of breakdown

If the safety locks and relays are in good working order, but the wipers:

  • ๐Ÿ›‘ They don't move at all. (Not even forced to move).
  • ๐Ÿ”„ Work in jerks Or they stop at extreme positions.
  • ๐Ÿ”Š They make a rattle or humBut the brushes are still there.

- guilty gear motor (original article number: 5E2 955 119 for the left janitor, 5E2 955 120 for the right one). On Octavia Tour This unit is going down because of:

Cause of failure Symptoms Solution
Motor brush wear Cleaners work only by force (by hand), not by a button. Replacement of brushes or gearbox motors in assembly
Jamming of gear gear gear Motor hum, but the brushes don't move. Disassembly and lubrication or replacement of the gearbox
Broken motor winding Complete lack of reaction, smell of burning Only a replacement gear motor
Corrosion of connector contacts Intermittent malfunctions Contact cleaning, processing Lithol

For diagnosis, remove plastic protection under the windshield and get to the gear motor. Check it out.

  1. Availability 12V on the connector when the wipers are turned on (use a multimeter).
  2. Ease of rotation of the motor shaft by hand (if the klinite is a problem in the gearbox).
  3. Integrity of wires from motor to block SCM.

Testing of voltage at the connector (should be 12V)| Shaft jamming test (manual)|Viewing of wiring on cliffs |Checking gear gear for wear-->

3. Wiring and contacts: where to look for a cliff?

On ล KODA Octavia Tour wiring the janitors through three-pointwhere most often there are breaks or oxidation:

  1. Gear motor connector (under plastic protection at the windshield).
  2. Comfort block SCM (under the dashboard, left of the steering wheel).
  3. Crossing the door hinges (If the windshield is replaced, the windshield is replaced.)

How to check wiring:

  • ๐Ÿ”Œ Testing with a multimeter: disable the gearbox connector and check the integrity of the wires from it to the block SCM (contacts T32/1 and T32/2).
  • ๐Ÿ” Visual inspection: look for melted or cracked wires with door hinges (especially after an accident or body repair).
  • ๐Ÿ› ๏ธ Cleaning contacts: use contact lubricant (for example, CRC 2-26) for the treatment of connectors.
โš ๏ธ AttentionIf you have recently changed the windshield, check if the master interrupted the wires of the wipers during installation. Nana Octavia Tour They pass right under the glass seal!
๐Ÿ’ก

Before disassembling the plastic protection of the wipers, take a photo of the location of all clips and bolts. Nana Octavia Tour they often break when dismantled carelessly.

4. The janitor switch: why doesnโ€™t it work?

If the wipers do not respond to the control lever, but the fuses and the gearbox motor are serviceable, the problem may lie in the control lever. steering column switch (item: 5E0 953 513). On Octavia Tour He's out of action because of:

  • ๐Ÿ’ง Moisture ingress (for example, after washing or rain).
  • ๐Ÿ”„ Wear of contact tracks (typical for cars with mileage >150 thousand km).
  • ๐Ÿ”ง Mechanical damage (For example, after a bad drive).

How to check the switch:

  1. Remove the plastic lining under the steering wheel (unscrew 2 bolts) Torx T20).
  2. Disconnect the switch connector and check the resistance between contacts when switching modes (should vary from 0 ohm up to infinity).
  3. If the resistance does not change, the switch is replaced.

On Octavia Tour with multifunction steering wheel (for example, RS or L&K) the wiper switch is integrated into the control unit. In this case, its replacement will cost more (from 8000 rubles).

How to temporarily restore the switch?

If the problem is in the oxidation of contacts, you can disassemble the switch, clean the tracks with alcohol and lubricate them. graphite lubricant. This will extend the life of the part by 3-6 months, but will not solve the problem forever.

5. Rain sensor (Rain Light SensorWhy do the janitors work themselves?

On Octavia Tour with option Rain Light Sensor (Rain and Light Sensor) The janitors can randomly Or, conversely, not to react to moisture. Reasons:

  • ๐ŸŒง๏ธ Sensor contamination (dust, fatty divorces from janitors).
  • ๐Ÿ”Œ Control unit malfunction (item: 5E0 955 559).
  • ๐Ÿ“ถ Calibration failed (for example, after replacing the windshield).

How to fix:

  1. Cleaning the sensor: wipe the glass over the sensor (located at the rearview mirror) with alcohol or glassware no silicone.
  2. Reset settingsTurn off the battery for 10 minutes, then recalibrate the sensor through the menu Settings โ†’ Assistants โ†’ Rain sensor.
  3. Wiring check: inspect the sensor connector (contacts) T10o/1 and T10o/2) for corrosion.

If the sensor is faulty, replacing it will cost 5 000โ€“7 000 โ‚ฝ (original) or 2 500โ€“3 500 โ‚ฝ (analogue from HELLA or Bosch).

๐Ÿ’ก

On Octavia Tour With a rain sensor, wipers may not work manually if the sensor is completely out of order. This is because the signal is going through the block. SCMThis block manual control when the sensor is mistaken.

6. Mechanical breakdowns: levers and trapezoids

If the wipers move, but They do not clean the entire glass area. Or get stuck in one position, the problem may be:

  • ๐Ÿ”ง Wear of leashes (leverages) They bend or break when heavy load (for example, if the wipers are frozen in winter).
  • โš™๏ธ Trapez breakage - a mechanism that transmits movement from the motor to the brushes.
  • ๐ŸงŠ Axle spelling corrosion (typical of cars that are rarely washed in winter)

How to diagnose:

  1. Remove the plastic protection under the windshield.
  2. Check the integrity of the levers and trapezoids (they should move smoothly, without backlash).
  3. Grease the axles of the brushes lithium grease (for example, LIQUI MOLY LM 47).

If the trapezoid is broken, it will cost you to replace it. 3 000โ€“5 000 โ‚ฝ (depending depending on the year of manufacture Octavia Tour). On models until 2017, the trapezoid is attached to 3 bolts, after 2017 - to 4 (article: 5E2 955 211).

7. Software failures: Resetting errors through VCDS

On ล KODA Octavia Tour electronically controlled SCM The janitors may not work because of software errors. For example:

  • ๐Ÿšจ Error B10CD - malfunction of the gear motor.
  • ๐Ÿšจ Error B10A1 - a break in the rain sensor circuit.
  • ๐Ÿšจ Error B1231 - a failure in the comfort unit.

How to reset errors:

  1. Connect the diagnostic scanner (VCDS, OBDeleven or Carista).
  2. Go to block 09 โ€” Cent. Elect. (Central Electronics).
  3. Select Clearing Codes (Reset errors).
  4. Reboot the system by turning off the battery for 5 minutes.

If errors occur again, the problem is hardware (motor, wiring, block) SCM).

โš ๏ธ AttentionDonโ€™t throw away mistakes without eliminating the cause! Nana Octavia Tour this could lead to lock-in and failure of other systems (e.g., central lock).

FAQ: Frequent questions about janitors ล KODA Octavia Tour

The wipers only work at first speed. What is the reason?

Most likely faulty mode switch (Wear of the second and third speed contacts) or the problem in comfort block SCM. Check the resistance of the switch in different positions. If it doesnโ€™t change, replace the lever.

After the cleaning, the janitors stopped working. What do I do?

Probably got the water in. gearbox or fuse box. Dry them with a hairdryer (cold air!) and process WD-40. If that doesn't help, check the fuse. F35 and relay J317.

The wipers move, but they don't clean the glass. Why?

The reasons may be mechanical:

  • ๐Ÿ”ง Wear leashes (levers) - they bend and they don't press on the glass.
  • ๐ŸงŠ Jamming brush-axis due to corrosion.
  • ๐Ÿงฝ Pollution rubberbrush (oil, silicone).

Check the back of the levers and lubricate the axles.

Is it possible to drive if the wipers don't work?

Technically yes, but this traffic violation (clause 4.1)If visibility through the windshield is impaired. In the rain or snow, you may be fined. 500 โ‚ฝ (Article 12.5 of the Administrative Code). Temporary solution - use handbrush or spray cleaner (for example, Sonax Xtreme).

How much does it cost to replace the motor-reducer wipers Octavia Tour?

The cost depends on the type of motor and the year of release:

  • ๐Ÿ”ง Original (article 5E2 955 119) โ€” 6 000โ€“8 000 โ‚ฝ.
  • ๐Ÿ”ง Analogue (Bosch, HELLA) โ€” 3 500โ€“5 000 โ‚ฝ.
  • ๐Ÿ‘จโ€๐Ÿ”ง Replacement work โ€” 1 500โ€“2 500 โ‚ฝ (depending on the service station).
