KMGDM KMGDM Review

There are few things more frustrating — and more dangerous — than driving in the rain and discovering that your windscreen wipers have stopped working because the stalk behind the steering wheel has failed. The combination switch, often called the wiper and indicator stalk, is one of the most frequently used controls in any vehicle, yet it is easy to take for granted until it breaks. Every time you signal a turn, flash your headlights, or switch on the wipers, you are relying on a set of electrical contacts and mechanical linkages inside this unassuming column-mounted switch. Over years of use, those contacts wear down, the plastic housing can crack, and moisture ingress can cause intermittent failures that leave you guessing whether your indicators are actually flashing. Replacing a faulty combination switch is one of the more straightforward DIY car repairs — it does not require opening the engine or dropping the gearbox — and a quality replacement unit restores the crisp, reliable click of your indicators and the smooth sweep of your wipers. For anyone who depends on their car for daily transport, a working combination switch is not a luxury; it is a basic safety requirement.

When buying a replacement combination switch for your vehicle, compatibility is the absolute first priority. These switches are model-specific — a stalk designed for one car will not fit another, and even different trim levels of the same model can use different switch assemblies. Always cross-reference the part number with your vehicle's VIN or the number printed on your existing faulty switch before ordering. Build quality varies enormously between original equipment (OE) parts, reputable aftermarket brands, and unbranded generic replacements. Look for switches with solid-feeling detents — the indicator and wiper positions should click into place with a positive mechanical action, not a vague mush. Waterproofing is another feature worth paying attention to: a well-sealed switch resists the moisture and condensation that can build up inside the steering column housing, preventing the intermittent electrical faults that are the hallmark of a failing switch. Finally, check the temperature rating — a switch rated from -40 °C to +85 °C will survive both winter frosts and summer heat without the plastic becoming brittle or the contacts expanding out of tolerance.

This review examines a replacement combination switch for the Stream Celebration MK6 (model years 2008 to 2017), covering the wiper, indicator, and headlight control functions in a single integrated unit. We look at the build materials — a mix of solid polystyrene and metal alloy — the waterproof sealing, the claimed 40% improvement in sealing performance over standard switches, and the extreme temperature tolerance. We also discuss installation complexity and whether this aftermarket unit represents good value compared to an original equipment part from the vehicle manufacturer.

This combination switch — referenced by part numbers 8A6T 17A553AB, 8A6T 17A553AA, and 8A6T 17A553AC — is designed as a direct replacement for the wiper, indicator, and headlight control stalk on the Stream Celebration MK6, covering model years from 2008 through to 2017. It integrates the wiper control (including intermittent, low-speed, and high-speed settings), the turn signal indicators, and the headlight beam selector — high beams, low beams, and flash-to-pass — into a single unit that mounts directly to the steering column. This is a multifunction assembly, not a single-purpose switch, and it replaces the entire stalk mechanism on the left side of the steering column.

The switch body is constructed from solid polystyrene plastic with internal metal alloy contacts and linkages. This material combination balances durability with weight — the polystyrene housing resists cracking from repeated use, while the metal contacts provide reliable electrical connectivity through thousands of switching cycles. A key design feature is the concentrated waterproof sealing structure: the internal cavity is sealed against moisture ingress, which the manufacturer claims delivers a 40% improvement in sealing performance compared to standard non-waterproof switches. This is particularly relevant in vehicles where condensation inside the steering column housing is common — a drop of water bridging the wrong contacts can cause phantom indicator flashes, wipers that refuse to turn off, or headlights that flicker unpredictably.

The switch is rated for operation in extreme temperatures ranging from -40 °C to +85 °C, which covers virtually any climate a vehicle is likely to encounter — from Nordic winters where the plastic needs to resist becoming brittle in sub-zero cold, to desert summers where interior temperatures can soar well above 50 °C. Installation requires removing the steering column shroud, which is typically held on by a few screws accessible from underneath the column. The old switch unplugs from the wiring harness and unbolts from the column bracket; the new switch fits in its place using the same mounting points. The electrical connector is a direct plug-and-play fit — no splicing, soldering, or modification of the vehicle's wiring is needed. Most DIYers with basic tools can complete the swap in 30 to 60 minutes.

The switch comes as a single unit — no additional wiring adapters, relays, or installation hardware are included beyond the switch itself. It ships in simple retail packaging. The black finish matches the factory look of the original Stream Celebration MK6 interior, so the replacement will not stand out as an obvious aftermarket part. The part is manufactured by KMGDM, a generic aftermarket brand, not by the original vehicle manufacturer. This means the fit and finish may differ slightly from an OE part — the detents might not feel quite as precisely weighted, and the plastic texture may not match the original exactly — but the electrical function and physical mounting should be equivalent.

As an aftermarket replacement part, this combination switch does not carry the same warranty or quality assurance as an original equipment component from the vehicle manufacturer. At the time of writing, the product has no customer reviews or star ratings, so buyers have no real-world feedback to judge longevity or fitment accuracy. The switch was first listed on Amazon on 23 April 2026, making it a very recent addition to the catalogue. Priced at €50.61, it is positioned as an affordable alternative to an OE switch — which could cost several times more from a main dealer — making it a pragmatic choice for owners of older Stream Celebration MK6 vehicles where the cost of a factory-original part would be disproportionate to the car's current value.

This combination switch is a targeted replacement part for Stream Celebration MK6 owners (2008-2017) whose original wiper/indicator stalk has failed, offering an affordable DIY fix that restores full column-switch functionality without the cost of a dealer-original part.
