- Before replacing the pump, check the fluid level, look for clogged nozzles, and inspect the 'WSH' fuse.
- The 2019-2022 Prius has separate pumps for the front and rear; ensure you are buying the correct one.
- An aftermarket Trico pump is a cost-effective and reliable alternative to the more expensive OEM part.
Is Your Windshield Washer Pump Failing?
A failing washer pump on your 2019-2022 Toyota Prius AWD-e can be a nuisance and a safety issue. When the pump stops working, you lose the ability to clean your windshield on the go. Here are the common signs that your washer pump needs attention.
Symptoms of a Bad Washer Pump
- No Fluid Spray: The most obvious symptom. You pull the lever, the wipers move, but no washer fluid comes out.
- No Pump Noise: You should hear a distinct buzzing sound from the front of the car when you activate the washers. If it's silent, the pump motor has likely failed.
- Weak or Inconsistent Spray: If the fluid just dribbles out or sprays unevenly, the pump motor might be getting weak and losing pressure. However, you should first check for clogged nozzles.
- Fluid Leaks: You might notice a puddle of blue, green, or orange washer fluid under the front passenger side of your car. The pump housing can crack and leak over time.
First, Check the Simple Stuff
Before you buy a new pump, make sure you've checked the basics. Is the washer fluid reservoir full? Are the washer nozzles on the hood clogged with wax or debris? You can use a small pin to clear them. Also, check the fuse for the washer system (labeled "WSH"). If these are all fine, the pump is the most likely culprit.
Choosing a New Aftermarket Washer Pump
For the 2019-2022 Prius AWD-e, you have two main choices: a new OEM (Original Equipment Manufacturer) pump from Toyota or a new aftermarket pump.
- OEM Toyota Pump: This is the exact part your car was built with. It guarantees a perfect fit and high quality, but it comes at a higher price.
- New Aftermarket Pump (Trico): Aftermarket parts are made by companies other than the original manufacturer. A quality aftermarket brand like Trico offers a reliable, cost-effective alternative. Trico pumps are designed to match OEM specifications for an easy installation without needing adjustments. For a simple and common part like a washer pump, a new aftermarket unit is often the smartest financial choice, providing similar performance and longevity to the original for less money.
Pro Tip: Front vs. Rear Pump
Your Prius has two separate pumps on the reservoir: one for the front and one for the rear. They look very similar but may have different connectors or mounting tabs. Make sure you are ordering the correct pump for the windshield you are servicing. The front pump is typically the one closer to the engine.

Frequently Asked Questions
Can I drive my Prius with a broken windshield washer pump?
Yes, but it's not recommended, especially in areas with bad weather or dusty conditions. Clear visibility is essential for safety, and a dirty windshield can be dangerous. It's best to get it fixed as soon as possible.
Is it hard to replace the washer pump myself?
It's a feasible DIY job for someone with basic tools. The process involves removing the front passenger wheel and part of the fender liner to access the washer fluid reservoir and pump. The pump itself just pulls out of a rubber grommet on the reservoir. The main difficulty is accessing the part, not replacing it.
Are there any recalls for the washer pump on the 2019-2022 Prius?
No. There are no specific recalls or common Technical Service Bulletins (TSBs) for the windshield washer pump on the 2019-2022 Toyota Prius AWD-e. A recall in 2019 for the Prius involved a brake booster pump, not the windshield washer pump.
How do I know if the pump is bad or if it's the switch on the steering column?
The easiest way to check is to listen for the pump's motor. If you hear a buzzing sound when you activate the washer, but no fluid comes out, the pump is likely working, and you have a clog or a leak in the lines. If you hear nothing at all and have already checked the fuse, the pump motor has most likely failed.
