Wiper system — normal behavior and malfunctions

Tags: #wiper · #rain-sensor · #relay · #part-number

Rear wiper clicking is normal: the rear wiper produces a clicking/ticking sound when activated. This is the normal electromagnetic switching action of the rear wiper relay, not a malfunction ¹²³.

Automatic rain sensor is unreliable: the automatic wiper/rain sensor operates unreliably — (1) it does not activate during heavy downpours when visibility is severely reduced; (2) it suddenly activates at excessive speed ("like a helicopter propeller") when it finally engages; (3) manual adjustment/configuration settings have minimal effect. Some owners had the sensor relocated/re-glued by a dealership without resolution; others disabled automatic mode entirely and use manual control exclusively. The issue appears to be an inherent sensor placement/calibration problem ⁴⁵⁶.

Rain sensor — additional reports (pre-facelift vs. restyle, and a successful calibration): the erratic behavior is again described as either barely triggering or running the wipers continuously "like helicopter blades." Pre-facelift (dorest) models reportedly have 3-speed rain-sensor modes that work better than the restyle version — an unconfirmed, single-report distinction. Manual control is the recommended workaround given the unreliability. One owner in Moscow reported having the sensor successfully calibrated, though the specific service/shop that did it is unknown ⁷⁸⁹.

Wiper relay intermittent malfunction: wipers can sometimes continue operating randomly for extended periods when they should stop after 3 sweeps. Workaround: pull the wiper stalk again to interrupt/reset, or restart the engine. Suspected root cause: corrosion on the steering-column relay ("подрулевое реле") electrical contacts — inspection/cleaning of the relay contacts may be needed ¹⁰.

Recommended wiper blades: Autoled-opt hybrid blades, 600/400 mm, hold up well (5–6 months of use per owner reports, good cleaning performance). SKYWAY 600/400 mm "buscane"-style blades are reported soft/flimsy with a poor clip design that cracks easily and mediocre cleaning. Winter performance varies in southern regions without salt/reagents on the roads ^{1112131415161718}.

Wiper linkage creak/squeak: apply WD-40 to the internal wiper linkage mechanism. Requires disassembly: unclip the wiper arms, remove the mounting clips, disassemble the linkage (~15 minutes of work), spray WD-40 inside, reassemble. Some owners added supplementary springs to the linkage for extra damping ^{1920212223242526}.

Weak wiper blade spring pressure: factory wiper-arm springs are weak and provide poor blade pressure, causing inadequate wiping. Fix: install an auxiliary spring device (available on Ozon) that clips onto the wiper-arm bracket and increases clamping force — easy to install/remove, effective per user reports. Alternative: relocate the spring's mounting point farther along the arm to increase mechanical advantage ^{2728293031323334353637}.

Rear wiper blade — part numbers: 350 mm blade, OEM part number 5CA167330; alternative LYNX LR35E 14"/350 mm. Available on Ozon and other Russian retailers. Uses a snap-on connector (no lock in the mounting mechanism). Aftermarket brands like Aviel (400 mm) also fit. On some versions only the rubber blade element needs replacing — about 5 minutes ^{3839404142434445}.

Rear wiper blade — removal/adjustment: the wiper arm has a release lever; the blade element slides in/out of the arm via a simple clip connection, taking 1–2 minutes to replace. If the blade doesn't make full contact with the glass center, try adjusting the spring bracket/clip tension on the arm before replacing the whole blade ⁴⁶⁴⁷⁴⁸.

Front wiper blade sizing — 65 cm (left) / 43 cm (right): recommended front wiper blade sizing is 65 cm on the left / 43 cm on the right. Root cause for needing a longer left blade: the standard 65 cm blade's curvature does not achieve full contact on the right side due to the windshield's curve, leaving a small unwiped strip on the right side and at the very top of the left blade's travel. ALCA brand wipers are reported as noticeably better quality/cleaning than cheap alternatives; no-name blades from Ozon (~410 RUB for the pair, RU market, April 2025) work but underperform compared to ALCA, especially on wider blades over time ^4950515253.

Driver-side wiper cleans poorly — tension-spring booster fix: if the driver-side wiper blade cleans poorly despite good blade quality, install a wiper-tension spring/enhancer (pressure booster) — generic universal 2-piece wiper tension-spring kits, available on Ozon and other retailers, improve contact pressure and cleaning effectiveness ^54555657.

Rear wiper nut cap — sourcing: a plastic cap/cover for the rear wiper's mounting nut is available on AliExpress under search terms "faw pentium x80", "besturn x80", or "bestune x80". Cost: under 1,000 RUB on AliExpress (RU market, February 2026). It's included with a complete rear-wiper assembly purchase, or can be bought separately for roughly 700 RUB (RU market, February 2026)

Rear wiper blade alternative — Masuma UR-14: the Masuma UR-14 rubber wiper blade is used by owners as an alternative to the OEM rear wiper blade, available from Ozon and other retailers ⁶³⁶⁴.
