Is Your B9 Tribeca's Windshield Washer Pump Failing?
A non-working windshield washer can be frustrating and unsafe. Before you assume the pump is bad, check the basics: make sure your washer fluid reservoir is full and that the washer nozzles on the hood aren't clogged with wax or debris. If those are fine, the pump itself is the next likely culprit.
Symptoms of a Bad Washer Pump
- No Sound, No Spray: You push the washer button and hear nothing. This is the most common sign of a dead pump motor or an electrical issue.
- Sound, But No Spray: If you can hear the pump motor humming but no fluid comes out, the issue could be a clog in the lines, a cracked hose, or an internal failure in the pump where the impeller is broken but the motor still spins.
- Weak or Uneven Spray: A pump that is failing may lose pressure, resulting in a weak stream that doesn't effectively clean the windshield.
Known Issues for the 2006-2007 Subaru B9 Tribeca

There were recalls for the windshield wiper motor on other Subaru models, but this is a separate part and did not specifically cover the B9 Tribeca. Failure of the washer pump is typically due to normal wear and tear over time.
Choosing a New Aftermarket Washer Pump

DIY Pro Tip
Replacing the washer pump is a common DIY job that can be done in under an hour. The pump is located at the bottom of the washer fluid reservoir, which is typically accessed by removing the front passenger-side wheel and the plastic fender liner. Have a bucket ready to catch the old washer fluid when you pull the pump out. Always use the new rubber grommet that comes with your new pump to ensure a good seal.
Frequently Asked Questions
Can I drive my B9 Tribeca with a broken washer pump?
Yes, but with caution. A broken washer pump doesn't stop the vehicle from running, but it creates a significant safety issue if your windshield becomes dirty from road spray, mud, or insects, impairing your vision. It's recommended to get it fixed as soon as possible.
Do I need to replace the front and rear pumps at the same time?
Not necessarily. The B9 Tribeca uses pumps for both the front and rear washers. If only one has failed, you only need to replace that specific one. However, since they are the same age, the other may not be far behind. The Trico 11-604 part is often listed for both front and rear applications.
How do I test my current washer pump?
First, have a helper activate the washer switch while you listen for a humming sound from the pump, usually located near the bottom of the fluid reservoir. If there's no sound, check the fuse first. If the fuse is good, you can use a multimeter to check for 12-volt power at the pump's electrical connector when the switch is activated. If you have power but the pump doesn't run, the pump has failed.
Is an aftermarket pump as good as the OEM Subaru part?
For this specific part, a quality aftermarket pump from a reputable brand like Trico is a perfectly acceptable replacement. The function is simple, and aftermarket brands often meet or exceed the original specifications for a lower price. Forum discussions among Subaru owners often support using aftermarket parts for non-critical components like this.
