The rear windshield wiper does not work on the ŠKODA Yeti: 7 reasons and how to fix the problem

Rear wiper on ŠKODA Yeti - a seemingly simple element, but its malfunction can cause a lot of inconvenience, especially in rainy weather or winter. If the rear window wiper stops working, do not rush to go to a service center: in 80% of cases, the problem can be solved on your own in 15–30 minutes. In this article we will analyze all possible reasons - from a banal blown fuse to worn out motor, and we’ll also give step by step instructions for diagnostics and repair.

Feature Yeti (like other models on the platform VW Group) is that the rear windshield wiper often fails due to oxidation of contacts in the motor connector - This is a “disease” of cars operated in humid climates. At the same time, in the cabin you may not hear the characteristic buzzing sound when you turn on the wiper, and the malfunction indicator on the instrument panel does not always light up. Next is a detailed analysis of each reason with photos, diagrams and repair tips.

1. Checking the fuse: the first diagnostic step

Let's start with the simplest thing - fuse F36 (10A), which is responsible for powering the rear wiper. B ŠKODA Yeti it is located in fuse box under the steering wheel (driver's side). To get to it:

1. Open the fuse box cover by pulling it towards you.
2. Find the fuse F36 (there is a diagram with symbols on the cover).
3. Remove it with tweezers and check visually - if the thread inside is burned out, replace it with a new one (10A only!).

If the fuse is intact, but the wiper does not work, don't rush to change it - the problem may be different. Also note: if the fuse blows again after replacement, this is a signal short circuit in the circuit (more about this in the section on wiring).

2. Diagnostics of the wiper motor: how to check without removal

Rear wiper motor Yeti - a weak point, especially after 100,000 km. Try it before you remove it ring the chain multimeter:

• 🔧 Step 1. Turn on the ignition and move the windshield wiper lever to the rear wiper position.
• 🔊 Step 2. Listen - if the motor hums, but the wiper does not move, the problem is mechanical part (drive rod or gear).
• 📊 Step 3. If there is silence, check the voltage at the motor connector (there should be 12V with the wiper on).

To check the voltage:

1. Remove the plastic rear door trim (it is secured with clips).
2. Disconnect the connector from the motor and connect the multimeter to it in DC 20V.
3. Ask an assistant to turn on the rear wiper - if there is voltage, but the motor does not work, it needs to be replaced.

Where to buy a motor for Yeti?

The original rear wiper motor for the ŠKODA Yeti has the article number 5E2 955 119 (or 5E2 955 119 A for restyled models). Analogues: Bosch 3397009276, Valeo 607301. Average price - 2500–4000 rubles. Before purchasing, check the year of manufacture of the car!

If the motor is “alive”, but the wiper does not move, check drive rod - it may break or jump off the gear. This is a common problem after severe frosts, when ice blocks the movement of the wiper.

3. Contact oxidation: hidden cause of malfunction

As mentioned earlier, oxidation of contacts in the motor connector is the most common reason for a non-working rear wiper on Yeti. Humidity, salt and temperature changes lead to the formation of a green coating on the terminals, which impairs contact.

To fix the problem:

1. Disconnect the connector from the motor (it is located under the plastic trim of the rear door).
2. Inspect the contacts - if they are green or white, they need to be cleaned.
3. Use fine sandpaper or a special contact cleaning fluid (for example, Kontakt 60).
4. After cleaning, apply silicone grease or Liqui Moly Electronic-Spray for protection against corrosion.

If after cleaning the wiper started working, but after a while the problem returned, replace the entire connector - oxidation could damage it from the inside. Article number of the original connector: 1K0 973 701.

4. Wiring problems: where to look for a break

Rear wiper wiring Yeti passes through corrugation between the body and the rear door. Over time, the wires fray or break due to the constant opening/closing of the door. To check the circuit:

• 🔍 Visual inspection. Remove the rubber corrugation and inspect the wires for fractures or melting.
• 📶 Test with a multimeter. Check the integrity of the wires from the fuse box to the motor (the resistance should be close to 0 ohm).
• 🔌 Checking the "mass". The rear wiper is grounded to the body through a bolt under the plastic cover - make sure that the contact is not oxidized.

If a break is detected, do not twist the wires - this is a temporary solution. It is better to solder the damaged area and insulate it with heat shrink tubing. If the wiring is severely damaged, replace it entirely (harness part number: 5E0 971 801).

Symptom	Probable Cause	Remedy
The wiper does not work, the fuse is intact	Oxidation of contacts in the motor connector	Cleaning contacts, treating with protective spray
The wiper buzzes but doesn't move	Broken drive rod or gear	Replacing the rod or motor assembly
The wiper works jerkily	Worn motor brushes or oxidation of contacts	Replacing brushes or cleaning contacts
The fuse blows again	Short circuit in wiring	Chain continuity check, replacement of damaged section

5. Faulty control lever or relay

Less often the problem lies in windshield wiper control lever or relay J317 (comfort control unit). If the rear wiper does not respond to activation, but the fuse and motor are working, check:

• 🎛️ Control lever. Try moving it in different directions - if the contacts inside are worn out, the wiper may work periodically.
• 🔄 Relay J317. It is located under the instrument panel (driver's side). Try removing it, cleaning the contacts, or replacing it with a known good one.
• 🖥️ Diagnostics with a scanner. If there are errors along the line CAN, the problem may be in the control unit.

To check the relay:

1. Remove the relay J317 (there is a diagram on the fuse box cover).
2. Swap it with a similar relay (for example, from the front windshield wipers).
3. If the rear wiper works, replace the relay with a new one (part number: 1K0 955 119 C).

6. Mechanical failures: rod, gear, fastening

If the motor hums, but the wiper stays still, the problem is mechanical part. On Yeti Most often they break:

• 🔗 Drive traction. The plastic rod connecting the motor to the wiper may crack or jump off the gear.
• ⚙️ Reducer gear. Due to wear or dirt, it may spin idle.
• 🔩 Wiper mount. If the mounting nut is loose, the wiper will hang loose and not clear the glass.

For repair:

1. Remove the rear door plastic trim.
2. Unscrew the motor (3 bolts on 10).
3. Check the integrity of the rod and gear. If they are damaged, replace them (rod article: 5E2 955 501).
4. Lubricate the gear Liqui Moly Silicone-Fett for smooth operation.

If the wiper “walks” or does not press against the glass, tighten the fastening nut (the key is on 13). But do not overtighten - this may damage the glass!

7. Diagnostics with a scanner: when you can’t do without it

If all the previous steps did not help, all that remains is computer diagnostics. On Yeti rear wiper controlled via bus CAN, and the problem may lie in:

• 📡 Control unit errors BCM. For example, code B11E8 indicates a motor circuit malfunction.
• 🔌 Line problems CAN. If the signal does not reach the motor, the wiper will not work.
• 🔄 Incorrect settings. Rarely, but it happens that after the firmware BCM The wiper control parameters are lost.

Suitable for diagnostics:

• Scanner VCDS (VAG-COM) - shows errors by ŠKODA as accurately as possible.
• Adapter ELM327 + program Torque Pro (for basic testing).
• Multi-brand scanner (for example, Launch X431).

If the scanner shows an error B11E8 or similar reset it and check if it comes back. If so, the problem is in the wiring or motor. If the error disappears, but the wiper does not work, the unit itself may be faulty BCM (reflashing or replacement required).

💡

On Yeti after 2014 block BCM may block the operation of the rear wiper if the rain sensor is faulty. Check its status in the menu Settings → Assistants → Rain sensor.

FAQ: Frequently asked questions about the rear windshield wiper ŠKODA Yeti

🔧 Why does the rear wiper only work at one speed?

Most likely faulty mode switch in the control lever or the contacts on the unit board have oxidized BCM. Try cleaning the contacts or replacing the lever (part number: 5E0 953 513). If the problem persists, diagnostics are required BCM.

❄️ The rear wiper does not work in winter - what is the reason?

In 90% of cases it is to blame ice, blocking the movement of the wiper. Do not force it on - this may burn the motor. Better:

1. Clear the glass of ice by hand.
2. Apply to wiper blade silicone grease or a special spray (for example, Sonax Anti-Frost).
3. Check to see if the drive rod is frozen to the gear.

💡 Is it possible to drive without a rear wiper?

Legislatively rear wiper is optional (unlike the front ones). However, in rain or snow it is serious security risk — visibility through the rear window is reduced by 70%. If the wiper is broken, use it temporarily anti-rain spray (for example, Rain-X), but repairs should not be postponed.

🔩 How to remove the rear wiper for replacement?

To remove the wiper:

1. Lift the plastic cap at the base of the wiper.
2. Unscrew the fastening nut (wrench on 13).
3. Pull the wiper towards you - it will be removed from the spline shaft.

When installing a new wiper do not overtighten the nut - this may damage the glass!

🛠️ How much does a service repair cost?

The cost of repair depends on the reason:

• Replacing the fuse - free (if you do it yourself) or 200–500 rubles. in the service.
• Cleaning contacts - 500–1000 rubles.
• Replacing the motor - 3000–5000 rubles. (with work).
• Wiring repair - 1500–3000 rubles.
• Diagnostics BCM — 1000–2000 rub.

The most expensive option is to replace the block BCM (from 15,000 rub.). But this is required extremely rarely.
