That little plastic cover is missing, and the exposed nut on your windshield wiper arm just looks wrong. I completely understand why locating the correct windshield wiper arm cap has been confusing so far. Let’s quickly figure out which design fits your vehicle perfectly. As someone who focuses entirely on the microscopic details of a finished product, I believe the absence of a simple cap fundamentally detracts from the overall vehicle aesthetic, leaving a raw, unfinished look that simply won’t do for 2025. I’ve personally tested these crucial components for fit, finish, and durability to determine which options truly deliver polish and protection.

THE HONEST TRUTH
This windshield wiper arm cap delivers on its structural promises, locking in place with that satisfying “click” I look for during installation. The only minor limitation is the very specific application range (Buick, Chevy, GMC), requiring careful cross-reference with the replacement part number before purchase.
2. GM Genuine Parts 22793593 Windshield Wiper Arm Cap
When dealing with Original Equipment, I expect a flawless fit, and during my test drive period, this GM Genuine Part truly lived up to the hype. I installed it quickly on a test Silverado, and the tight tolerances immediately signaled that it was engineered precisely for the vehicle’s specific geometry. I love knowing that these parts are validated by GM engineers, integrating the latest material science into something as small as a wiper nut cover.
QUICK SPECS
– Manufacturer: GM Genuine Parts

THE HONEST TRUTH
I found this component feels robust and provides the peace of mind only OE quality offers, confirming it performs exactly as intended in harsh conditions. However, because it’s a Genuine Part, the price point is noticeably premium compared to the aftermarket options I also tested.
3. ApplianPar 2Pcs Front Windshield Wiper Arm Nut Head Bolt Cap
There is nothing worse than the visible rust and grime buildup on an exposed wiper arm nut, which completely ruins the clean look of the front fascia. This ApplianPar twin-pack is the perfect solution, instantly hiding that unsightly maintenance area and restoring the vehicle’s polished finish. I appreciate that they provide compatibility spanning multiple platforms, including popular truck lines like the Silverado and the Enclave SUV.
QUICK SPECS
– Package Quantity: 2 x Wiper Arm Nut Cap
– Compatibility Range: Wide list of Chevrolet, GMC, Buick models

THE HONEST TRUTH
I highly recommend this option for owners managing multiple compatible vehicles or those who just want an affordable spare windshield wiper arm cap ready to go. My observation is that while the fit is secure on most listed models, the plastic finish is slightly less matte than the highest-end OE models.
4. Carbhub 2Pcs Windshield Wiper Arm Cap Cover Fit Encore Silverado
I tested this Carbhub unit directly against the ApplianPar option, and while they share similar wide vehicle compatibility, I found the Carbhub version provided a marginally smoother contour and a deeper black pigment. It’s truly exciting to see this level of fit and finish emerging in the highly competitive aftermarket category. This option replaces the key part number 95271190, making cross-referencing very straightforward for many common vehicles.
QUICK SPECS
– Part Number: Replaces 95271190
– Package Quantity: 2 x Wiper Arm Nut Cap
– Fitment: Buick Encore, Chevrolet Trax, GMC Acadia, Yukon
– Aesthetics: Deep black finish
– Value: High cost-effectiveness
THE HONEST TRUTH
This budget-friendly cap excels at providing high value and includes two pieces, which is fantastic for managing replacements and unexpected losses. The main trade-off I noticed is that installation required slightly more pressure to achieve the final, secure lock compared to the OE units.
Comparison Insights: Matching Fit and Finish to Your Needs
When looking at these options, I immediately see three distinct price brackets based on my testing. The GM Genuine Part sits clearly in the premium tier, offering the highest level of material assurance and the most secure fit, perfect for advanced users who prioritize originality and manufacturer specifications. The KEVWR model offers a mid-range blend of specific OE replacement number engineering and exceptional value, providing high durability without the high OE sticker shock. Finally, the ApplianPar and Carbhub units are excellent budget options, ideal for beginner enthusiasts needing multiple caps without heavy investment, though I found the Carbhub had a slight edge in finish quality over the ApplianPar.
What I Prioritize in a Windshield Wiper Arm Cap
When I evaluate something that seems as simple as a windshield wiper arm cap, I immediately focus on compatibility, material durability, and the mechanism’s security. It’s pointless if the part looks great but flies off the first time you hit the highway! I always look for heavy-duty ABS or similar plastics that resist UV damage, because dull, gray plastic defeats the whole purpose of improving the aesthetic. My field testing ensures that the replacement parts have been accurately molded to the specified OE dimensions, guaranteeing that tight, factory-fresh lock.
Another factor I prioritize is the replacement part number; if the aftermarket manufacturer provides a direct cross-reference, I trust that the fit will be precise, which significantly reduces my installation time. I recommend checking the small clips and internal teeth for signs of cheap molding, as these critical points are what keep the nut protected from corrosion long-term. In my experience, a well-made cap should last for years, so I treat this selection process as a small but important investment in vehicle maintenance and appearance.
Application Types & Best Options
If you are tackling a comprehensive restoration or a meticulous maintenance project where maintaining originality is key, I absolutely suggest splurging on the GM Genuine Parts cap; its materials are validated specifically for the intended platform. For the daily driver enthusiast who just needs reliable protection and an aesthetic upgrade without breaking the bank, I found the mid-range KEVWR model offers the best balance of engineering and price. This is a great choice for long-term functional replacement.
When the goal is sheer value or acquiring replacements for multiple vehicles across a compatible fleet, the multi-packs like ApplianPar or Carbhub are fantastic. For high-mileage drivers who encounter frequent road debris or harsh winter conditions, remember that the budget options might need replacement more frequently than the robust OE model. Ultimately, the best option hinges on whether your priority is exact factory spec or excellent low-cost protection.
Final Verdict: Choosing Your Next Windshield Wiper Arm Cap
After extensively testing multiple options, I feel confident saying that selecting the right cap is a surprisingly impactful way to finalize the polished appearance of your vehicle’s front end while ensuring critical components are protected. The key to satisfaction here is confirming compatibility first, then deciding how much you value factory specifications versus multi-pack value. All four options I reviewed perform the basic function well, but they differentiate themselves significantly on fit tolerance and material resilience.
My Recommendations by Budget Tier:
- Premium Investment: Choose the GM Genuine Parts 22793593 if you own a compatible OE vehicle and demand the highest level of validated quality and material longevity. This is the gold standard of fit.
- Best Mid-Range Value: I suggest the KEVWR Wiper Arm Cover 15776792 for drivers seeking reliable durability backed by a specific OE replacement number without the top-tier OE price point.
- Budget & Multi-Vehicle: Go with the Carbhub 2Pcs Cap. I found it had a slightly better overall finish quality and contour compared to the ApplianPar, making it the superior choice for stocking spares.
Common Questions About Windshield Wiper Arm Cap
What Is the Purpose of a Windshield Wiper Arm Cap?
The primary function of the windshield wiper arm cap is both aesthetic and functional; it covers the exposed mounting nut or bolt that attaches the wiper arm to the drive shaft. This prevents the metal nut from being exposed to rain, road salt, and debris, which significantly reduces the risk of corrosion and rust that could eventually seize the wiper arm in place.
How Do I Know Which Wiper Nut Cover Fits My Vehicle?
The most reliable way to ensure correct fitment is by cross-referencing the replacement part number listed by the cap manufacturer with the original equipment (OE) number for your specific year, make, and model. If a specific OE number isn’t provided, double-check the detailed compatibility list provided by aftermarket suppliers, paying close attention to specific model years.
Are All Wiper Arm Nut Caps Universal?
Definitely not; I advise caution against assuming universality, even if the general shape looks similar. Wiper arm shafts and the nuts that attach them vary widely in size and taper across different auto manufacturers and even between models from the same brand. Using an incorrect size can result in a loose fit that falls off easily or one that is too tight and risks damaging the plastic clip mechanism.
Can I Drive If My Wiper Arm Cap Is Missing?
Yes, you can certainly drive without the small plastic cap, but I strongly advise replacing it as soon as possible. While the car remains operational, the exposed metal nut will immediately begin to corrode when exposed to moisture, making future wiper arm replacement or maintenance much more difficult due to rust accumulation.
What Material Provides the Best Durability for a Wiper Arm Cap?
In my experience, high-quality ABS (Acrylonitrile Butadiene Styrene) plastic or a similar automotive-grade polymer is ideal. I look for materials that are specifically rated for UV resistance, as sun exposure causes brittle plastic and color fade over time, especially in darker colors like black. OE parts often use advanced, temperature-stable polymers.
