Windshield wiper relay Škoda Octavia Tour: do-it-yourself diagnostics, repair and replacement

Škoda Octavia Tour - a car known for its reliability, but even in it, small but critical parts fail over time. One of these is wiper relay, failure of which may make it impossible to use the wipers in rain or snow. In this article we will look at how to independently diagnose a malfunction, select a replacement and install a new relay without contacting service.

Problems with wipers are often attributed to wear on the brushes or motor, but in 30% of cases the relay is to blame. It is responsible for intermittent operation, overload protection and correct shutdown of the brushes. If your Octavia Tour (especially models A5 or A7) started to behave strangely - the wipers work chaotically, do not stop in the down position or do not respond to the switch at all - it’s time to check the relay.

We have collected all the necessary information: from malfunction symptoms up to step-by-step replacement instructions, including numbers of original and analog spare parts. You will also learn how to do without a relay in an emergency and what mistakes are most often made during repairs.

Symptoms of a bad windshield wiper relay

Wiper relay on Octavia Tour rarely fails suddenly - usually the failure is preceded by characteristic symptoms. The main thing is not to ignore them, so as not to be left without working windshield wipers in bad weather.

Main features:

• 🔄 The wipers only work in one mode (eg only at high speed or only in intermittent mode).
• ⚡ Brushes do not stop in down position, freezing in an arbitrary place.
• 🛑 Complete lack of reaction to the wiper switch (the fuse is intact).
• 🔥 The relay makes clicking noises or smells burning - this is a sign of an internal short circuit.
• ⏱️ Intermittent mode does not work, although other speeds function.

On Octavia Tour (especially pre-facelift versions) a common problem is when the wipers turn on by themselves when you turn the ignition key. This is also related to the relay - its contacts could “stick” due to oxidation or overheating.

⚠️ Attention! If the wipers suddenly stop working during the rain, do not try to “knock” the relay with a hammer - this may permanently damage it. Instead, try manually returning the brushes to the down position to avoid damaging the mechanism when turning it back on.

Another indirect sign - blown fuse F36 (10A), which is responsible for the wiper circuit. If it burns out regularly, the problem is in the relay or motor, and not in the wiring.

Where is the windshield wiper relay located? Škoda Octavia Tour

Depending on generation Octavia Tour Relay location may vary. In most cases it is in fuse box under the steering wheel, but sometimes it is moved to an additional block under the hood.

For an accurate search, use the table:

Generation Octavia Tour	Year of issue	Relay location	Socket number
1U (A4)	1996–2004	Fuse box under steering wheel (left)	R12 or J317
1Z (A5)	2004–2013	Fuse box under the steering wheel (on the right, behind the cover)	J317 (position 4)
5E (A7)	2013–2020	Fuse box under the hood (near the battery)	SB22 or J657
FL (A7, facelift)	2017–2023	Fuse box under the steering wheel (behind the plastic panel)	J317 (position 7)

On Octavia Tour A5 (most common generation) the wiper relay is usually located next to the relay heated rear window and low beam. To get to it:

1. Open the driver's door and remove the fuse box cover (it is secured with latches).
2. Find the diagram on the back of the cover - the wiper relay is marked as J317 or R12.
3. Carefully remove the relay by pulling it up (do not use excessive force to avoid breaking the latches).

If your model has a fuse box under the hood (as on A7), look for a black plastic box next to the battery. The wiper relays there are usually marked blue or green.

How to test the windshield wiper relay with a multimeter

If you suspect that the relay is faulty, it can be checked without removing it from the vehicle. For this you will need multimeter (or at least a 12V test lamp) and a screwdriver.

Verification algorithm:

1. Remove the relay from the nest (as described above).
2. Set the multimeter to mode calls (or resistance measurements).
3. Connect the probes to the contacts 85 and 86 (relay coil). Resistance must be within 50–120 Ohm. If the device shows a break or zero, the relay is faulty.
4. Serve 12V to contacts 85 and 86 (possible from battery). You should hear a click - this means that the winding is working properly.
5. Check your contacts 30 and 87 in open and closed states (before and after 12V supply). In the open state the resistance should be infinite, in the closed state it should be close to zero.

If the relay does not click when voltage is applied or the contacts 30 and 87 does not close, it must be replaced. Also inspect the case for melting or cracks This is a clear sign of failure.

⚠️ Attention! On some Octavia Tour A7 The wiper relay is integrated into the comfort control unit (BCM). In this case, it cannot be checked separately - diagnostics with a scanner is required (for example, VCDS).

If you don't have a multimeter at hand, you can use replacement method: replace the suspicious relay with a known good one (for example, the heated rear window relay, if it is identical in number). If the wipers work, the problem is confirmed.

Selection of spare parts: original vs analogues

When replacing the wiper relay with Octavia Tour can be used as original spare parts from Škoda, and analogues from third-party manufacturers. The main thing is to ensure compatibility by part number.

Original relays for different generations:

• 🔧 Octavia Tour A4 (1U): 1J1 953 253 or 1J1 953 253 A
• 🔧 Octavia Tour A5 (1Z): 1K1 953 253 B or 1K1 953 253 C
• 🔧 Octavia Tour A7 (5E): 5E0 953 253 or 5E0 953 253 A

Among the analogues, the following have proven themselves well:

• 🏆 HELLA — 4RA 003 507-011 (suitable for A5 and A7)
• 🏆 Bosch — 0 332 019 150 (universal, but check the contacts)
• 🏆 Valeo — 403001 (for A4)
• 🏆 Febi Bilstein — 11695 (quality budget option)

When choosing an analogue, pay attention to:

• 🔌 Contact location - they must match the original.
• 📏 Case dimensions - some relays are similar in appearance, but do not fit in size.
• 🔋 Rated voltage - must be 12V (on some universal relays it is indicated 24V, they won't fit).

⚠️ Attention! On Octavia Tour A7 since 2017, relays with additional protection against moisture (labeling IP67). If you take an analogue one, make sure that it is also waterproof, otherwise the relay will quickly fail.

The cost of the original relay is from 800 to 1500 rubles, analogues will cost 300–700 rubles. It is better to buy parts in trusted stores (for example, Exist.ru, Autodoc or from authorized dealers) to avoid counterfeits.

How to distinguish an original relay from a fake?

Original relay Škoda/VW has:

- Clear markings with the brand logo (no blurry letters).

- The case is made of matte plastic (counterfeits are often glossy).

- Contacts made of brass (for fakes, they are made of steel, which quickly oxidizes).

- The inscription “Made in Germany” or “Made in Czech Republic” (Chinese fakes do not have this).

Step-by-step instructions for replacing the relay

Replacing the windshield wiper relay with Škoda Octavia Tour - one of the simplest procedures that even a beginner can handle. The main thing is to maintain consistency and not confuse the nests.

Required tools:

• 🔧 Flathead screwdriver (for removing the fuse box cover).
• 🔧 Tweezers (if the relay is tight in the socket).
• 🔧 Multimeter (optional, to test the new relay before installation).

Procedure:

If after replacement the wipers do not work correctly:

1. Check whether the relay is installed correctly (an inverted relay will not work).
2. Make sure that the contacts in the socket are not oxidized (clean them with alcohol if necessary).
3. Check the fuse F36 (10A) - it could burn out due to a short circuit.

On Octavia Tour A7 after replacing the relay it may be necessary reset adaptations via a diagnostic scanner (for example, VCDS or OBDeleven). This is due to the fact that the comfort control unit (BCM) remembers the parameters of the old relay.

Common replacement mistakes and how to avoid them

Even such a simple procedure as replacing a relay can result in new problems if mistakes are made. Here's what's most often done wrong:

Error 1: Using a relay from a different model

Relay from Octavia A5 and Octavia A7 similar in appearance, but may differ temporary characteristics (eg delay in intermittent mode). If you install the wrong relay, the wipers will operate jerkily or at the wrong speed.

Mistake 2: Ignoring oxidized contacts

If the contacts in the fuse box socket are oxidized, the new relay will quickly fail. Be sure to clean them alcohol or special contact fluid (for example, Kontakt 60).

Error 3: Incorrect relay installation

The relay can be inserted into the socket two ways (turned 180°). If you put it on the wrong side, the wipers will either not work or the fuses will blow. Refer to the contact markings (30, 85, 86, 87).

Mistake 4: Buying cheap analogues without checking

Some Chinese relays (such as brand NoName) have inappropriate winding resistance, which causes them to quickly overheat. Before installation, test the new relay with a multimeter.

Mistake 5: Forgetting to check the wiper motor

If the relay is OK, but the wipers do not work, the problem may be motor or mechanical part (for example, the levers are jammed). Do not rush to change the relay - first make sure that the motor is receiving power.

Temporary solution: how to do without a relay

If the windshield wiper relay fails on the road and there is no replacement at hand, you can temporarily connect the wipers bypassing the relay. This is not safe for electronics, but will help you get to your home or service.

Method 1: Direct connection to battery

Disconnect the connector from the wiper motor and connect it to 12V directly from the battery (via fuse 10A!). The wipers will only work at one speed, but that's better than nothing.

+12V (from the battery) → Contact “53” of the motor
Ground → Motor contact "31"

Method 2: Using a relay from another circuit

If there is an identical relay in the fuse box (for example, for heated seats or rear window), you can temporarily swap them. The main thing is to make sure that the relays have the same numbers.

Method 3: Manual wiper control

On Octavia Tour A5/A7 You can manually move the wipers by turning drive gear under the plastic trim at the base of the windshield. This is labor-intensive, but will help in an emergency.

⚠️ Attention! Long-term operation of wipers without a relay can lead to motor overheating or short circuit. Use temporary solutions only to get to the point of repair.

On Octavia Tour A7 with the system Rain Light Sensor (rain sensor) bypassing the relay may cause an error in the control unit. In this case, a temporary solution will not work - you will have to go by tow truck or tug.

FAQ: Frequently asked questions about the wiper relay Škoda Octavia Tour

Can the wiper relay be repaired or is it just a replacement?

Theoretically, the relay can be disassembled and the contacts cleaned, but in practice this is impractical. Modern relays are made non-separable (the housing is sealed), and after disassembly they lose their tightness. It is better to immediately replace it with a new one.

Why does a new relay burn out quickly?

If the new relay fails after a short time, the problem lies not in it, but in:

• 🔌 Short circuit in the wiring.
• 🔋 Overload of the wiper motor (for example, due to a jammed mechanism).
• 💧 Moisture has entered the fuse box.

Before installing a new relay, check the circuit for the absence of KZ and make sure that the motor rotates freely.

Which fuse controls the windshield wipers? Octavia Tour A5?

On Octavia Tour A5 (1Z) The safety lock is responsible for the wipers F36 (10A) in the driveway block. If it burns regularly, look for the cause in the relay or motor.

Can I put a relay on Golf or Passat?

Yeah, but only if the details match. For example, a relay from VW Golf IV (1J1 953 253) suitable for Octavia Tour A4and relay Passat B6 (3C0 953 253) - for Octavia A5. Always check the catalogs ETKA or Elcats.

What if after replacing the relay wipers work in the opposite direction?

This means you have confused polarity when you plug in the motor. Nana Octavia Tour The direction of work of janitors depends on what contacts are submitted +12V and mass. Change the places of the wires on the contacts 53 and 53b (if your model has them).
