THE HONEST TRUTH
This unit provides excellent material quality and peace of mind thanks to the good warranty, making it ideal for daily drivers. My only slight concern is that it comes without the washer pump, requiring careful transfer of the existing component, which adds a minimal step to the installation process.
6. A-Premium Rear Windshield Wiper Motor Compatible with Jeep Grand Cherokee
For those working on slightly older vehicles, like the 1999-2004 Grand Cherokees or the early Liberty models, paying attention to the specifications is absolutely vital. I had to pay close attention to the connector type here because this unit features a 5-Pin connector, which dictates the exact functionality and integration with the vehicle’s computer system for speed control. Analyzing the specs, I noted how many different OE numbers (like 55155122AG) it replaces, showing its versatility within that older generation platform. The design promise is that it takes delicate technology to match the original function, ensuring that both intermittent and full speed modes work exactly as intended.
QUICK SPECS

It meets or exceeds OEM specifications, which is a fantastic baseline for anyone looking for reliable daily performance without having to worry about complex wiring or setup.
QUICK SPECS
– Replacement Part Numbers: 15173034, WPM1049
– Location: Rear
– Operating Mode: Power with Pulse
– Quality: Engineered To Meet Or Exceed OEM Specifications
THE HONEST TRUTH
This is an incredibly robust and hassle-free solution for large GM SUVs and trucks, offering crucial pulse functionality right out of the box. While the testing confirms reliability, like all generic “exceed OEM” claims, I always factor in the possibility that it might need replacement sooner than a Motorcraft unit when making long-term purchase decisions.
Comparison Insights Based on My Testing
When stacking these seven options against each other, the differences become clear based on cost and intended usage. The Motorcraft WM693 sits firmly in the premium category, making it the top choice for owners who prioritize absolute OE-level trust and long-term durability, even if it means a higher upfront cost. It’s perfect for the advanced user or professional who needs guaranteed compatibility.
Moving into the mid-range are the four A-Premium units (P2, P5, P6). These are fantastic for the intermediate DIYer. Their key difference is the tight focus on specific OE fitment and connector pin counts (3, 5, or 8 pins), demanding that the buyer accurately verify their vehicle’s specs before purchasing. They offer a great balance of quality materials and a solid warranty.
Finally, the BDELI (P1) and OEG Parts (P4, P7) fall into the budget-friendly and accessible mid-range. The key differences here are often the underlying certifications (P1 boasts IATF certification, which is excellent) and the availability of specific features like the Pulse functionality (P7). These are ideal for beginners focused on simple, cost-effective repairs without complex requirements.
What I Prioritize in Rear Window Wiper Motor
Based on my time tearing apart and installing dozens of these units, I can tell you that successful installation relies almost entirely on three key factors: specifications, compatibility, and reliability. First and foremost, you must verify the exact OE part number and the connector pin count—a 3-pin motor will not function in a 5-pin harness, regardless of the vehicle model year. I’ve found that high-quality units, even aftermarket ones, feel notably heavier and have tightly sealed plastic casings, indicating better internal components that resist moisture intrusion. Never skimp on matching the features; if your original motor had a pulse or intermittent function, you must ensure the replacement rear window wiper motor explicitly supports that functionality, as I noted with the OEG Tahoe unit.
Application Types & Best Options
If you are tackling a Daily Driver project where reliability is paramount but budget is a concern, I generally steer people toward the A-Premium line. I found that their quality assessment is strong, and the one-year warranty provides great confidence. For Older Vehicles (Pre-2007), like the earlier Jeep Grand Cherokee models, I recommend the A-Premium 5-Pin or OEG units; you need specialized fitment, and those brands tend to have better cross-references for those harder-to-find components. If the vehicle is an investment or needs guaranteed OEM performance, I always recommend biting the bullet and going for the Motorcraft option (P3), as I’ve learned that the peace of mind is worth the extra cost, especially for high-mileage or inclement weather driving.
Final Verdict: My Top Picks for Rear Window Wiper Motor Replacements
After testing these motors in various simulated conditions—from steady rain to prolonged intermittent operation—I have developed a clear hierarchy based on performance, build quality, and value. Finding a dependable rear window wiper motor is easier when you match the complexity of the repair to the quality of the component.
Summary of Key Findings:
For guaranteed, flawless operation and zero fitment headaches, the Motorcraft unit (P3) remains the undisputed champion; it’s an OE standard component that simply works. If you require excellent aftermarket value without sacrificing quality, the A-Premium options (P2, P5, P6) consistently provide superior component quality, especially in terms of robust casing and seamless connector fitment, provided you accurately match the pin count to your vehicle. The BDELI and OEG units are fantastic entries that bring necessary features like pulse mode and high certifications down to a more accessible price point for the average DIYer.
Recommendations by Budget Level:
- Premium Investment (Ultimate Durability): Motorcraft Wiper Motor (P3). Choose this if you want true OE quality and the highest trust factor.
- Best Value Mid-Range (Quality & Warranty): A-Premium Rear Windshield Wiper Motor (P2, P5, P6). Excellent for specific fitments and vehicles under 10 years old.
- Budget & Feature Focused (DIY Friendly): OEG Parts New Rear Wiper Motor W/Pulse (P7) or BDELI New Rear Windshield Wiper Motor (P1). Great for older vehicles or basic fixes where cost is the primary factor but key features like pulse are still needed.
Recommendations by Vehicle Age/Need:
- Modern Vehicle Replacements (Specific Connectors): The A-Premium 3-Pin or 8-Pin options (P2, P5) are perfectly engineered to integrate with modern vehicle systems.
- Classic/Older Platforms (Complex Part Search): The A-Premium 5-Pin (P6) or the OEG units (P4, P7) provide excellent compatibility for platforms where original parts are becoming scarce.

Your Rear Window Wiper Motor Questions Answered
What Are the Rear Window Wiper Motor That Offer the Best Longevity?
In my experience, the Motorcraft units offer the highest proven longevity because they adhere strictly to original equipment manufacturing (OEM) specifications, often utilizing superior internal components like heavier copper windings and better-sealed casings compared to generic aftermarket alternatives.
How Can I Verify the Correct Pin Count on My Wiper Motor Connector?
The most reliable way is to physically inspect the old, failed motor before ordering the replacement. You must count the visible metal contacts within the plug opening on the motor housing. If the old motor is completely missing, checking the wiring harness plug in the vehicle or cross-referencing the OE number using a dealer parts lookup site is mandatory.
Does the Country of Origin Affect the Quality of Aftermarket Wiper Motors?
While many excellent aftermarket parts are manufactured globally, I have found that brands investing in external certifications like IATF 16949 (like the BDELI unit) generally exhibit more consistent quality control, regardless of the manufacturing location, due to strict process adherence.
What Does the “Pulse” Feature Mean on a Wiper Motor Replacement?
The pulse feature refers to the motor’s ability to handle intermittent wiper settings, allowing the wiper arm to pause between cycles. If your vehicle has an intermittent rear wiper setting, you must select a replacement motor that specifically states it includes or supports the pulse functionality, such as the OEG Tahoe unit.
Is it Necessary to Transfer Gearing or Components from the Old Motor to the New One?
Typically, a new rear wiper motor is a complete plug-and-play assembly, including the internal gearing and control module. However, some aftermarket motors, like certain A-Premium options I tested, do not include the washer fluid pump, requiring you to carefully remove and transfer the existing pump to the new motor housing.
