INFINITI M35 Windshield Washer Pump Guide (2006-2010)
Everything an owner needs to know when the washer fluid stops spraying on your 2006-2010 M35.
- A failed washer pump is a common issue, with symptoms being no spray or no sound from the motor.
- Before replacing the pump, check for simple fixes like a blown fuse, clogged nozzles, or a pinched fluid line.
- An aftermarket pump from a brand like Trico is a reliable and much more affordable alternative to an OEM part.
- DIY replacement is manageable for beginners and involves removing the passenger-side front wheel and fender liner for access.
Is Your INFINITI M35 Windshield Washer Pump Failing?
A failed windshield washer pump can be a safety issue, especially in bad weather. Diagnosing the problem is usually straightforward. The most obvious sign of a bad pump is when you activate the switch and no fluid sprays out, but you can still hear the wiper blades move. Before blaming the pump, check for a few other simple issues first.
- Listen for the Pump: With the engine off, have someone activate the washer switch while you listen near the front passenger-side wheel. You should hear a distinct buzzing sound from the motor. If you hear nothing, the pump or its electrical circuit is likely the problem.
- Check the Fuses: A blown fuse can stop the pump from getting power. Check the fuse box for any fuses related to the wipers or 'electrical items'.
- Look for Clogs and Leaks: Inspect the small spray nozzles on the hood for dirt or wax buildup. Also, check under the front passenger side of the car for any blue, green, or orange fluid that would indicate a leak from the reservoir or the pump itself.
A Note on the Low Fluid Level Sensor
The M35/M45 can sometimes experience issues where the low fluid warning light stays on even with a full reservoir. This is caused by a separate float sensor, not the pump itself. Owners have reported that gunk and slime can build up at the bottom of the reservoir, causing the float to stick. Cleaning the reservoir during a pump replacement is a good preventive measure.
Choosing a New Aftermarket Pump
When replacing the washer pump on your M35, you have two main choices: a new aftermarket part or an Original Equipment (OEM) part from an INFINITI dealer. For a simple component like a washer pump, a quality aftermarket part offers significant savings without a compromise in performance.
- OEM: An OEM pump is identical to the one your car was built with. However, INFINITI may primarily sell the pump as part of a complete reservoir assembly, which increases the cost significantly.
- Aftermarket: Aftermarket brands like Trico produce direct-fit replacement pumps designed to meet or exceed original specifications. These parts are engineered for easy installation and provide a cost-effective and reliable repair. Given the high cost of an OEM unit, a reputable aftermarket pump is the most practical choice for this repair.
| Part Type | Estimated Cost |
|---|---|
| New Aftermarket Pump | $20 - $40 |
| New OEM Pump | $90 - $110 |
| Shop Labor | $73 - $107 |
| Total Professional Replacement (Aftermarket Part) | $93 - $147 |
| Total Professional Replacement (OEM Part) | $174 - $208 |
DIY Installation is Possible
Replacing the washer pump on an M35 is a beginner-friendly job that can be done in about an hour. The process involves safely jacking up the front passenger side, removing the wheel, and partially detaching the plastic fender liner to access the reservoir and pump. The pump itself simply pulls out of a rubber grommet on the reservoir. This is a great way to save on labor costs.
Frequently Asked Questions
Are there any recalls for the 2006-2010 M35 washer pump?
No, there are no active recalls or Technical Service Bulletins (TSBs) from INFINITI or the NHTSA for the windshield washer pump on the 2006-2010 M35.
Why do I hear the pump but no fluid comes out?
If you can hear the pump motor running, the issue is likely a blockage or a leak. Check for clogged nozzles on the hood, or a cracked or disconnected fluid hose between the pump and the nozzles. On some Infiniti models, the washer fluid line can get pinched by the battery if it was recently replaced.
Does the M35 have a separate pump for a rear window?
No, the INFINITI M35 is a sedan and does not have a rear window wiper or a separate rear washer pump. The single pump services the front windshield only.
Can I use a universal washer pump?
While universal pumps exist, it is highly recommended to use a direct-fit, vehicle-specific pump for your M35. A direct-fit model ensures the electrical connector and mounting style match perfectly, making installation much easier.
