Subaru WRX (2012-2021) Windshield Washer Pump Replacement Guide
A clear windshield is essential for safe driving, and a working washer pump is key to that visibility.
- A silent pump motor is the most common sign of failure; listen for the hum.
- Replacement is a simple DIY job, usually taking less than an hour.
- A quality aftermarket pump from a brand like Trico is a reliable, cost-effective alternative to OEM.
- Always check the fuse and for clogged nozzles before ordering a new pump.
Is Your WRX Washer Pump Failing?
A faulty windshield washer pump can be more than an annoyance; it can be a safety hazard. If you activate the washer and nothing happens, or the spray is weak, it's time to diagnose the problem. Often, the pump itself is the culprit.
Common Symptoms of a Bad Washer Pump
- No sound from the pump: When you activate the washer, you should hear a distinct humming sound from the pump motor. If it's silent, the pump has likely failed or isn't receiving power.
- Pump runs, but no fluid sprays: If you can hear the pump working but no fluid comes out, the issue could be clogged nozzles, a leak in the system, or an internal failure in the pump.
- Weak or uneven spray: A dying pump may lose the ability to generate enough pressure, resulting in a weak stream that doesn't effectively clean the windshield.
First, Check the Basics
Before replacing the pump, make sure the washer fluid reservoir is full. Also, check the fuse for the washer system to ensure it hasn't blown. Sometimes, the nozzles can get clogged with wax or debris; a small pin can often clear them.
Choosing the Right Aftermarket Pump: OEM vs. Trico
When it's time for a replacement, you have two main choices: a genuine Subaru (OEM) pump or an aftermarket option. For the 2012-2021 WRX, both are viable, but they serve different needs.
- OEM Subaru Pump: An original equipment manufacturer part is a direct replacement for the one that came with your car. It guarantees a perfect fit and original performance. However, OEM pumps typically cost more.
- Trico Aftermarket Pump: Trico is a long-standing brand in wiper and washer technology, founded in 1917. Their aftermarket pumps are designed to meet or exceed OEM specifications for a trouble-free installation. For a part like a washer pump, a quality aftermarket brand like Trico offers a reliable and cost-effective alternative to the more expensive OEM part.
Pro Tip: Aftermarket Value
For a simple, non-performance-critical part like a windshield washer pump, a reputable aftermarket brand like Trico provides excellent value without a noticeable difference in day-to-day performance compared to an OEM part.

Frequently Asked Questions
Is it difficult to replace the washer pump on a 2012-2021 WRX?
No, it is a relatively easy job. The pump is typically located at the bottom of the washer fluid reservoir, accessible by removing a few clips and part of the fender liner in the front passenger-side wheel well. The pump itself just pulls out of a rubber grommet. The entire process can usually be done in under an hour with basic hand tools.
Are there any recalls for the WRX washer system?
There are no specific recalls for the windshield washer pump on the 2012-2021 WRX. However, there was a recall for the windshield wiper motor on some 2010-2014 Legacy and Outback models, which share some platform similarities with the 2012-2014 WRX. This recall does not apply to the washer pump itself.
Do I need a special pump for the front and rear windows?
WRX sedans only have a front washer system, so a single pump is used. On WRX hatchback models (prior to 2015), a dual-outlet pump or two separate pumps might be used to supply the rear washer. Always verify the specific part needed for your vehicle's body style.
What is the OEM part number for the WRX washer pump?
Several part numbers can fit this year range. A common one for the 2015-2021 WRX is 86611SG000. For earlier models, numbers like 86611AJ100 or 86611AG000 may be applicable. It's always best to confirm fitment with your vehicle's VIN.
