Is Your INFINITI EX35 Washer Pump Failing?
A non-functional windshield washer system is more than an annoyance; it's a safety issue. If your 2008-2012 EX35 isn't spraying fluid, the washer pump is a common culprit. Diagnosing the problem is usually straightforward and replacement is a job most owners can handle themselves.
Symptoms of a Bad Washer Pump
- No Sound, No Spray: You pull the lever and the wipers move, but you hear no humming sound from the front of the car and no fluid comes out. This often points directly to a dead pump motor or an electrical issue like a blown fuse.
- Pump Hums, But No Fluid: If you can hear the pump motor running but nothing hits your windshield, the issue could be an empty reservoir, clogged nozzles, or a blockage in the lines. A failing pump might also make noise but be too weak to push fluid.
- Weak or Uneven Spray: If the fluid barely reaches the windshield or sprays unevenly, it can be caused by a pump that is losing pressure or clogged nozzles.
- Leaking Fluid: Puddles of blue or purple fluid under the front passenger side of your vehicle can indicate a cracked reservoir or a dried-out rubber grommet where the pump seals into the tank.
Check the Simple Things First
Before ordering a new pump, confirm your washer fluid reservoir is full. Also, check the fuse for the washer system. If the fuse is blown, the pump won't receive power. A repeatedly blowing fuse can signal a failing pump that is drawing too much current.
Choosing a New Aftermarket Washer Pump
For a 2008-2012 EX35, which does not have complex driver-assist systems tied to the windshield, a quality aftermarket washer pump is a reliable and cost-effective choice. The technology is simple, and brands like Trico specialize in producing direct-fit replacements that perform like the original.
- OEM (Original Equipment Manufacturer): This is the part you would get from an INFINITI dealer. It's guaranteed to fit perfectly but comes at the highest cost. The OEM part number for the EX35 is 28920-CA000.
- Aftermarket (Trico and others): Aftermarket brands produce parts designed to meet or exceed original specifications. A brand like Trico offers an OE-style pump that installs without any modifications needed. For this part, the primary difference between OEM and a reputable aftermarket option is the price and the absence of the INFINITI logo on the part itself.
When replacing the pump, it's a good idea to also purchase a new rubber grommet that seals the pump to the reservoir. They are inexpensive and can prevent leaks.

Frequently Asked Questions
Where is the washer pump located on my EX35?
The windshield washer pump is located at the bottom of the washer fluid reservoir tank. You can access it by removing the front portion of the passenger-side front wheel well liner.
Is this a difficult DIY job?
No, this is considered an easy repair for most DIYers. It involves turning the wheel for access, removing a few plastic clips and screws, pulling back the fender liner, and then simply pulling the old pump out and pushing the new one in. No special tools are required.
Do I need to replace the front and rear pumps?
The INFINITI EX35 uses a single, dual-outlet pump for both the front and rear windshields. The pump reverses its motor direction to send fluid to either the front or the back. If neither is working, the pump is likely the cause.
My 'Low Washer Fluid' light is on, but the tank is full. Is that the pump?
No, that is a separate component called the washer fluid level sensor. It is also located on the reservoir, often near the pump, but is a different part with its own electrical connector. If your pump is working but the light is stuck on, you need to replace the sensor, not the pump.
