Nippon Power Window Kit Universal w/3 Switches Review

One Month Later: Nippon Power Window Kit Universal w/3 Switches Review

My aging daily driver, a classic hatchback that’s seen better decades, was starting to show its age in more ways than one. The most persistent annoyance, however, wasn’t a rattle or a squeak, but the increasingly stubborn manual window cranks. One particularly sweltering afternoon, wrestling with a window that refused to budge, I knew it was time for an upgrade. That’s when I stumbled upon the Nippon Power Window Kit Universal w/3 Switches. This kit promises to convert two manual windows to power, a tantalizing prospect for bringing a touch of modern convenience to a vintage ride.

Initially, I was a bit skeptical. Universal kits often mean compromises, and I’ve learned that lesson the hard way with other aftermarket automotive accessories. However, the allure of ditching those clunky cranks and the relatively straightforward claims on the packaging were enough to pique my interest. The kit presented itself as a neat package, ready to tackle the task of modernizing my car’s windows.

Comparing it to the daunting prospect of fabricating custom power window mechanisms or searching for rare, often exorbitantly priced OEM parts, this universal Nippon kit seemed like the most practical path forward. My first impression upon unboxing was one of pleasant surprise; the components felt solid, and the included hardware suggested a thorough consideration of the installation process. It wasn’t just a motor shoved into a box; there seemed to be a genuine effort to provide a complete solution. This initial impression was one of cautious optimism, a feeling that this might actually be a worthwhile endeavor.

Real-World Testing: Putting Nippon Power Window Kit Universal w/3 Switches to the Test

First Use Experience

My testing ground for this power window kit was my own garage, specifically on my 1990s hatchback, over the course of a weekend. The primary goal was to replace the manual window cranks on both front doors with the new electric motors and associated hardware. I opted to install it in a typical DIY automotive environment, under standard garage lighting and with basic hand tools.

The initial installation was, to put it mildly, an intricate dance. While the kit includes a comprehensive array of parts, the process of fitting the motor and actuator mechanism behind the door panel required patience and a good understanding of automotive interiors. The instructions, while present, could have benefited from more detailed diagrams specific to common door panel constructions. However, once the components were properly positioned and secured, operating the switches for the first time was genuinely satisfying. The motors whirred to life, smoothly raising and lowering the windows with an ease I hadn’t experienced in years.

There were a few moments of confusion, particularly when figuring out the exact orientation of the adapters and brackets for optimal window travel. This required some trial and error, fitting and refitting pieces until they felt just right. Despite these minor hurdles, the overall ease of use once installed was remarkable. The three switches provided offered flexibility; I used one for the driver’s side, one for the passenger side, and kept the third as a spare or for potential future expansion. There were no major surprises or quirks that rendered the system unusable, but the learning curve for installation was steeper than anticipated.

Extended Use & Reliability

Over the past month, this Nippon kit has become an integral part of my daily driving routine. Opening and closing windows is no longer a struggle, a small but significant quality-of-life improvement. The motors operate consistently, whether it’s a quick adjustment on the highway or a slow roll-down when parking.

In terms of durability, the kit has held up remarkably well. I haven’t noticed any signs of wear and tear on the motors, switches, or the adapter mechanisms. The windows move with the same smooth action as they did on day one, without any jerking or hesitation.

Maintenance has been practically non-existent, which is exactly what I look for in aftermarket car parts. A quick wipe-down of the door panels and switches is all that’s been needed. There’s nothing specific to watch out for in terms of upkeep; the components seem robust. Compared to the old manual regulators, which were prone to binding and eventual failure, this power window system feels far more reliable. It certainly outperforms the flimsy feel of some other universal kits I’ve encountered in the past, and it offers a significant upgrade over the original manual system.

Breaking Down the Features of Nippon Power Window Kit Universal w/3 Switches

Specifications

The Nippon Power Window Kit Universal w/3 Switches is designed for universal application across a wide range of automobiles, aiming to bring power windows to vehicles that were originally equipped with manual cranks. This kit is engineered to convert two manual windows into power-operated ones, a key specification for anyone looking to upgrade their older vehicle. It features quiet motors, which is a welcome detail, as I’ve dealt with noisy aftermarket components before.

The motors themselves are built with a Cuprum bearing and a POM plastic gear wheel. These materials suggest a focus on durability and smooth operation. Cuprum, or copper alloy, is known for its low friction and good conductivity, while POM (polyoxymethylene) plastic is a high-strength, low-friction engineering thermoplastic commonly used in gears and mechanical components. The kit includes a generous amount of hardware: (2) electric window motors (left and right), (2) caps, (2) circlips, (2) retainer rings, (4) speednuts, (2) adapters, and (2) gears specific to the motor drive mechanism.

Additionally, there are (8) brackets, (8) rubber bushings, and (8) metal bushings provided to ensure secure mounting and vibration dampening. For assembly, the kit comes with (20) 4 x 16 screws and (22) 3 x 5 screws, offering plenty of options for securing various components. The inclusion of (3) switches means you have one for each window you’re converting, plus a spare. The overall color of the visible components, such as the switches, is typically black, fitting in with most automotive interior aesthetics.

These specifications are critical because they detail the actual components you’ll be working with. The inclusion of specific bearings and gear materials hints at longevity. The sheer volume and variety of mounting hardware suggest that Nippon has attempted to account for various mounting scenarios found in different car doors. Having a spare switch is a thoughtful touch for a DIY kit. Compared to other simpler kits that might just offer a motor and a basic switch, this Nippon package seems more comprehensive.

Performance & Functionality

The primary function of the Nippon Power Window Kit Universal w/3 Switches is to reliably convert manual window mechanisms into powered ones. In this regard, it performs exceptionally well. The window operation is smooth and surprisingly quiet, living up to its advertised feature. Raising or lowering the windows takes mere seconds, and the motors have enough torque to handle the window glass without straining, even on a slightly inclined track.

The quiet motors are a definite highlight. Unlike some older power window systems that sounded like a small animal trapped in a metal box, these units produce a muted, efficient whir. The included switches are responsive, with a satisfying click when actuated, and they provide the precise control needed for subtle window adjustments. The fact that the system is designed to be installed behind the door panel means the visible components are minimal and unobtrusive, preserving the interior’s original look.

One of the key strengths is the universal fit claim, which, while requiring careful installation, generally holds true. It successfully adapted to the existing window regulator mechanism in my vehicle. A minor weakness could be the initial setup complexity for individuals unfamiliar with automotive door panel removal and wiring. However, once properly installed, the functionality is exactly as one would expect from a factory-equipped power window system.

Design & Ergonomics

The design of the Nippon Power Window Kit Universal w/3 Switches prioritizes function and hidden integration. The motors are compact enough to fit within the confined space behind most door panels, which is a significant design achievement for a universal kit. The switches, which are the only visible components after installation, are ergonomically designed with a comfortable shape and tactile feedback.

The build quality of the visible components, like the switches, feels solid. The plastic housing is robust, and the button mechanism feels durable enough for daily use. The motors themselves are housed in what appears to be sturdy metal casings, suggesting they are built to withstand the vibrations and temperature fluctuations common in automotive environments. The inclusion of Cuprum bearings and POM plastic gear wheels in the motor’s internal gearing points to a design consideration for longevity and reduced wear.

Ergonomically, the switches are a pleasure to use. Their placement is customizable during installation, allowing you to position them where they are most accessible and comfortable for the driver and passenger. There’s no real learning curve for the operation; it’s as intuitive as any factory power window switch. The tactile feedback from the switches is good, providing a clear indication that the command has been registered.

Durability & Maintenance

Based on my month of use, the durability of the Nippon Power Window Kit Universal w/3 Switches appears to be excellent for its intended purpose. The components are designed for the rigors of automotive use, and the materials used, like the Cuprum bearings and POM plastic gear wheels, suggest long-term reliability. There have been no signs of degradation, binding, or performance loss in the windows since installation.

Maintenance for this kit is virtually nil. Once installed, the system requires no special cleaning or lubrication beyond what would be standard for the interior of a car. The motors are sealed units, and the mechanical parts are designed to operate without user intervention. This lack of maintenance is a significant advantage, especially when compared to older manual regulators that could seize or require regular greasing.

Potential failure points, common in any electromechanical system, would likely be related to electrical connections or, over a very extended period, motor wear. However, the robust construction and the inclusion of protective hardware like rubber and metal bushings suggest that Nippon has tried to mitigate these risks. For a kit that’s designed to be hidden and forgotten, its low-maintenance profile is a strong selling point.

Accessories and Customization Options

The Nippon Power Window Kit Universal w/3 Switches is quite comprehensive in terms of included accessories, covering most needs for converting two windows. The core components include the (2) electric window motors, the (3) switches, and all the necessary adapters, gears, caps, circlips, and retainer rings to connect the motor to the window regulator mechanism. The extensive hardware assortment, including brackets, speednuts, and a variety of screws, offers significant flexibility during installation. The (8) rubber bushings and (8) metal bushings are crucial for ensuring a smooth, vibration-free operation, effectively acting as damping accessories.

While the kit itself doesn’t offer modular “customization” in the traditional sense of interchangeable parts (beyond selecting the best mounting positions), the universality and the range of included hardware allow for a degree of adaptation to different vehicle door interiors. The inclusion of a spare switch provides a practical form of “customization” by offering a backup or the potential for future expansion to another window, though additional motors would be required for that. The kit is designed to integrate with existing manual window regulator mechanisms, rather than replacing them entirely.
