Everything you need to know when your Buick Enclave's windshield washer stops working.

- Before replacing the pump, check the washer system fuse and listen for a humming sound to confirm the pump is the issue.
- Replacement is a feasible DIY project, requiring access behind the passenger-side wheel well liner.
- A quality aftermarket pump from a brand like Trico offers a reliable and cost-effective alternative to more expensive OEM parts.
Is Your Washer Fluid Not Spraying?
A common issue for Buick Enclave owners is a sudden failure of the windshield washer system. Usually, the first sign is that no fluid sprays out when you pull the lever. Before assuming the pump is dead, it's wise to check a few simple things first. Make sure your washer fluid reservoir is full. Next, check the fuse for the washer system, which can be a common and easy fix. 🎬 Watch: How to find and replace the washer pump fuse You can also listen for the hum of the pump motor when you activate the switch; if you hear nothing, the pump is likely the problem.
Symptoms of a Failing Washer Pump
When the washer pump in your Enclave starts to fail, the signs are usually straightforward. Understanding them can help you confirm the pump is the problem 🎬 See this guide on testing and replacing your washer pump before you buy a replacement.
- No Sound from the Pump: When you try to use the washers, you should hear a faint humming sound from the front passenger side of the vehicle where the pump is located. If it's silent, the pump motor has likely failed or is not receiving power.
- No Fluid Spray: If the pump motor is silent and no fluid comes out of the nozzles on either the front or rear windshield, it's a strong indicator of a failed pump (or a blown fuse).
- Weak or Inconsistent Spray: A pump that is wearing out may lose its ability to create enough pressure, resulting in a weak, sputtering stream of fluid that doesn't effectively clean the windshield. However, this can also be caused by clogged nozzles, so it's a good idea to clean the nozzle openings with a small pin first to rule that out.
- One System Works, The Other Doesn't: Your Enclave has separate pumps for the front and rear. If the rear washer works but the front doesn't (or vice-versa), it strongly suggests the pump for the non-working system has failed.
Known Issues and Recalls
There are no major recalls for the windshield washer pump itself on the 2008-2022 Buick Enclave. However, a recall was issued for some 2008 models equipped with the optional Heated Washer Fluid System (HWFS), which involved disabling the heating module due to a fire risk. Additionally, some 2016 models were recalled for a faulty windshield wiper motor, which is a separate part from the washer pump. These issues are not related to the standard washer pump's reliability.
Choosing a New Aftermarket Pump
When replacing the washer pump, you have the choice between an Original Equipment Manufacturer (OEM) part from the dealer and an aftermarket part. OEM pumps are designed for a perfect fit but come at a higher price. Aftermarket pumps from brands like Trico are designed to meet or exceed original specifications and offer a more affordable, reliable alternative. For a part like a washer pump, a quality aftermarket unit provides excellent value without sacrificing performance. Trico is a well-regarded brand known for making durable, easy-to-install replacement parts.
Generation and Part Differences
The Buick Enclave has two generations in this year range: 2008-2017 (Gen 1) and 2018-2022 (Gen 2). While the function is the same, the part numbers for the washer pumps may differ. For example, an OEM part number for Gen 1 is 22766715, while a common number for Gen 2 is 84993622. Always verify the part fits your specific model year before purchasing.

Frequently Asked Questions
Is the front and rear washer pump the same part?
No, the Buick Enclave uses two separate pumps that are mounted on the same reservoir. One is for the front windshield and the other is for the rear window. They are typically not interchangeable, so you must order the specific pump you need to replace.
How do I know if it's the pump or just a clog?
First, listen for the pump's motor. If you hear it humming but no fluid comes out, you could have a clog in the lines or nozzles. You can try cleaning the nozzles with a pin. If you hear nothing at all (and the fuse is good), the pump itself has failed.
Is it hard to replace the washer pump myself?
For a DIYer with some experience, it is a manageable job. The pump is located behind the passenger-side front wheel well liner. The process involves jacking up the vehicle, removing the wheel and the plastic splash guard to access the reservoir and pumps. It typically takes about an hour.
🎬 Watch: Step-by-step walkthrough for replacing the washer pumpDo I need to drain the washer fluid to replace the pump?
Yes, fluid will spill out when you remove the old pump from the reservoir's grommet. It's best to have a bucket ready to catch the fluid. You can either drain it beforehand or let it drain when you pull the pump out.
