Škoda Octavia A5 is one of the most popular models of the Czech brand, but even its little things wear out over time, which sometimes cause great inconvenience. The rear windshield wiper is a seemingly simple item, but a malfunction can turn a rainy drive into a nightmare. In this article we will look at everything you need to know about the rear windshield wiper. Octavia A5: from the selection of original and analog parts to step-by-step replacement, taking into account typical errors.

Owners Octavia A5 (2004–2013) often encounter problems with the rear wiper: it may squeak, do not adhere well to the glass, or stop working altogether. The reasons lie in brush wear, motor failure or broken wiring. We analyzed reviews from car owners, technical documentation and the experience of service centers to compile the most complete guide possible. There is no water here - only specific data, articles and proven solutions.

Design and principle of operation of the rear windshield wiper

Rear wiper Octavia A5 consists of several key components:

  • 🔧 Electric motor — sets the wiper lever in motion. Installed under the plastic panel in the rear door.
  • 📏 Lever (rocker arm) - a metal or plastic part connecting the motor to the brush.
  • 🧹 Wiper blade — a rubber element in direct contact with the glass. Has standard fasteners U-hook (9x3).
  • ⚡ Wiring and fuse - are responsible for powering the system. fuse F36 (10A) located in the block under the steering wheel.

The operating principle is simple: when the control lever is activated (usually this position 1 or 2 on the steering column switch) current flows to the motor, which drives the lever through a gearbox. The movement is transmitted to the brush, which cleans the glass. B Octavia A5 The rear wiper works synchronously with the washer - if the fluid does not flow, the brush can “dry” rub the glass, which accelerates its wear.

An important feature of the model: in Octavia A5 Since 2008, a rear wiper motor with the article number has been installed 1Z2 955 115, whereas in earlier versions (before 2007) there was 1Z2 955 115 A. These parts are not interchangeable!

📊 How often do you change your rear wiper blade?
  • Every season
  • Once every 2 years
  • Only when it stops working
  • Never changed

Typical faults and their diagnosis

If the rear wiper Octavia A5 stopped working, first check:

  1. fuse F36 (10A) — its failure completely de-energizes the system. Located in the fuse box under the steering wheel (to the left of the pedals).
  2. Brush condition — if the rubber is cracked or peeled off, the brush will not fit tightly to the glass.
  3. Wiring — a common problem: breakage or oxidation of contacts in the motor connector.
  4. Motor - if the wiper does not move, but the fuse is intact, most likely the motor winding has burned out.

You can diagnose a breakdown without tools:

  • 🔊 The wiper won't turn on - check the fuse and voltage on the motor (should be 12V with the ignition on).
  • 🔄 The wiper moves jerkily - the problem is in the motor gearbox or contamination of the mechanism.
  • 💧 The brush leaves streaks — rubber wear or glass contamination (for example, wax after washing).
⚠️ Attention: If the wiper works, but the glass remains dirty, do not rush to change the blade. Often to blame clogged washer nozzle - it can be cleaned with a needle or compressed air.
Symptom Probable Cause Solution
The wiper does not respond when turned on Fuse blown F36 or wiring break Replace the fuse, check the circuit with a multimeter
The brush “sticks” in one position Worn motor gear gear Replacing a motor or gearbox (part number 1Z2 955 115 B)
The wiper squeaks when working Dry friction due to lack of lubrication in the lever joints Lubricate the hinges with silicone grease or WD-40
The brush does not press against the glass The lever spring is weak or the fastening is deformed Bend the lever or replace the spring (part no. 1Z2 955 211)

Selecting a windshield wiper blade: original vs analogues

Original rear wiper blade for Octavia A5 has an article number 1Z2 955 415 A (length 300 mm). However, its price often bites - from 1,200 to 1,800 rubles. There are worthy analogues on the market:

  • 🏆 Bosch 3397004666 — German quality, soft tires, price ~800 ₽.
  • 💎 HELLA 8WC 351 029-131 — optimal price/quality balance (~600 ₽).
  • 🔹 SWF 112000300 — budget option (~400 ₽), but the resource is lower.
  • 🌍 Denso DW-030L - Japanese brand, suitable for harsh winters (~900 ₽).

When choosing, pay attention to:

  • 📏 Brush length - should be straight 300 mm (tolerance ±5 mm).
  • 🔗 Mounting type - only U-hook (9x3), otherwise it won't work.
  • 🌡️ Frost resistance — cheap brushes become tanned when −20°C.
⚠️ Attention: Brushes with graphite coating (for example, Bosch Aerotwin) last longer, but may leave gray marks on the glass when used dry. If you often have the rear wiper on without a washer, it is better to choose classic tires.
💡

Before buying a brush, measure the old one - sometimes after replacing glass (for example, with tinted glass), a brush 1-2 cm shorter is required.

Step-by-step replacement of the rear wiper blade

Replacing the brush is the simplest procedure, which takes no more than 5 minutes. You only need a new brush and a flat-head screwdriver (if the fastener is stuck).

☑️ Tools and materials

Done: 0 / 4

Step 1. Preparation

Raise the wiper lever perpendicular to the glass (to the “service” position). If it does not lock, place a cloth under it to avoid damaging the glass.

Step 2. Removing the old brush

Press the plastic clip where the brush is attached to the lever (usually located at the bottom). Pull the brush down and it should come off without effort. If the latch does not budge, carefully pry it off with a screwdriver.

Step 3. Installing a new brush

Align the new brush mount with the lever and press until it clicks. Make sure that the latch snaps into place - pull the brush down, it should not come off.

Step 4. Check

Turn on the rear wiper and washer. The brush should fit tightly to the glass and not leave streaks. If you hear a squeaking noise, apply some silicone grease to the arm joints.

What to do if the brush does not come off?

If the latch is broken and the brush “sits” dead, cut it off with a knife and remove the remaining plastic with pliers. New lever (item no. 1Z2 955 211) worth ~1 500 ₽, but this is an extreme case.

Replacing the rear wiper motor

If the problem is with the motor, replacing it will require more time and tools. B Octavia A5 it is accessed through a plastic panel in the rear door.

Required tools:

  • ⚒️ Socket wrench T20 and T25.
  • 🔧 Flathead and Phillips screwdrivers.
  • 🔌 Multimeter (to check voltage).
  • 🧴 Silicone grease.

Step 1. Removing the plastic panel

Remove the plastic rear door trim (it is held on by 4 clips and 2 screws T20 under the handle). Using a flat-head screwdriver, carefully pry up the clips, starting at the bottom corner.

Step 2. Disconnecting the motor

Disconnect the power connector from the motor (it is black with 3 pins). Check with a multimeter: the middle contact should have 12V with the wiper on. If there is no voltage, the problem is in the wiring or switch.

Step 3. Removing the old motor

Unscrew 3 screws T25, securing the motor to the body. Remove the wiper arm (it sits on the spline shaft - pull up firmly). Remove the motor along with the gearbox.

Step 4. Installing a new motor

Before installing a new motor (1Z2 955 115 B for models after 2008) lubricate the spline shaft and gearbox. Connect the connector and check the operation of the wiper before final assembly.

⚠️ Attention: When assembling, make sure that The wiper lever is set to its original position (parallel to the bottom edge of the glass). If you place it crookedly, the brush will hit the door seal.
💡

When replacing the motor, always check the condition of the wiring - often oxidation of the contacts in the connector causes repeated failure.

Repair of the wiper arm and mounts

Rear wiper arm (rocker arm) Octavia A5 Over time, it becomes deformed or breaks at the point of attachment to the motor. Main problems:

  • 🔩 Spring weakening — the brush does not press against the glass.
  • 💥 Crack in plastic hinge — the lever is “playing”.
  • 🔄 Spline connection wear — the lever rotates on the motor shaft.

How to repair:

  1. Weak spring: Bend it with pliers or replace it (item no. 1Z2 955 211 A).
  2. Crack in the lever: Weld the plastic with a soldering iron or replace the entire lever (1Z2 955 211, ~1 500 ₽).
  3. Backlash on the shaft: Remove the lever, clean the splines from corrosion and place on Loctite.

If the lever is bent (for example, after unsuccessful parking), it can be straightened by heating it with a gas burner. However, after such repairs the metal becomes brittle - it is better to buy a new one.

💡

Before repairing the lever, take a photo of its original position relative to the glass - this will help you set the angle correctly after assembly.

Prevention and care of the rear windshield wiper

To the rear wiper Octavia A5 served longer, follow simple rules:

  • 🚿 Use washer — do not turn on the wiper “dry”. In winter, add to the tank anti-freeze with silicone (for example, Liqui Moly Scheiben-Frostschutz).
  • 🧴 Lubricate the hinges - Apply silicone grease to the lever joints every six months.
  • 🧼 Wash your brush — once a month, wipe it with soapy water to remove dirt and wax.
  • ❄️ Winter preparation — before frost, treat the rubber of the brush with glycerin so that it does not tan.

Avoid common mistakes:

  • ❌ Do not use household WD-40 to lubricate the hinges - it washes away the factory lubricant. Better take it CRC 2-26.
  • ❌ Don't put universal brushes with adapters - they will not provide the required pressure.
  • ❌ Don't ignore creaking - it signals wear of the hinges or lack of lubrication.

If the wiper starts to “bounce” while working, check lever angle. Over time, it sags and the brush loses contact with the glass. The solution is to bend the lever up 2–3 mm.

FAQ: Frequently asked questions about the rear windshield wiper Octavia A5

Is it possible to supply a brush of a different length, for example 350 mm?

No, this will cause the brush to touch the door seal or not reach the edges of the glass. Original length - 300 mm, deviation is allowed ±5 mm.

Why does the rear wiper work but the glass remains dirty?

There are several reasons:

  • The brush rubber is worn out (replace it).
  • The washer nozzle is clogged (clean with a needle).
  • The glass is coated with wax or silicone (rinse antisilicon).
  • The brush is installed upside down (turn it over).
How to check the motor without removing the panel?

Connect the multimeter to the motor connector (black connector under the plastic panel). When the wiper is on, the middle contact should be 12V. If there is voltage, but the wiper does not work, the motor is burned out.
