Is Your Windshield Washer Pump Failing?
A failed windshield washer pump is more than an inconvenience; it's a safety issue when dirt, salt, or road spray obstructs your view. For 2003-2008 INFINITI FX45 owners, the most common sign of failure is when you activate the washers and nothing happens. If you don't hear the familiar, faint humming sound of the pump motor, the pump itself has likely failed.
Before You Buy a New Pump
First, check the basics. Make sure your washer fluid reservoir is full. Then, check the fuse for the washer system, which is located in the fuse box in the engine compartment. Sometimes a simple clogged nozzle can be the problem, which can be cleared with a small pin. If the fuse is good, the tank is full, and you hear no sound from the pump, it's time for a replacement.
Choosing an Aftermarket Washer Pump for Your FX45
When replacing the washer pump on your FX45, you have two main choices: a new OEM part from the dealer or a new aftermarket part. While an OEM pump is a guaranteed fit, it can be significantly more expensive.
Aftermarket brands like Trico offer a compelling alternative. These pumps are designed to meet or exceed original equipment specifications, ensuring a direct fit without any need for modification like drilling or special adjustments. Trico pumps are made from durable plastic and are known for their reliable performance and easy installation, making them a popular choice for DIY repairs. For the FX45, an aftermarket pump provides the same function as the original at a much lower cost.

A Note on Installation
On the INFINITI FX45, the washer fluid reservoir and pump are typically located behind the front passenger-side wheel well. To access it, you will need to jack up the vehicle, remove the wheel, and then remove or pull back the plastic fender liner. While the pump itself just pushes into the reservoir, getting to it requires some disassembly.
Frequently Asked Questions
My front washers work but the rear doesn't. Is it the same pump?
The FX45 uses a single reservoir tank for both front and rear washers, but it may have two separate pumps or a dual-outlet pump located on that tank. If one has failed, you only need to replace the specific pump for that function. The Trico pumps available are typically for the front windshield.
Is this a difficult DIY job?
It's a moderately easy job for a DIYer with basic tools. The main challenge is not the pump itself, but accessing it. You'll need a jack, jack stands, and tools to remove the wheel and fender liner clips or screws. The pump replacement itself is usually tool-free.
The spray is weak, but I hear the pump. Is the pump bad?
Not necessarily. A weak spray can be caused by a partially clogged nozzle, a pinhole leak in the washer fluid lines, or a clogged filter at the pump's intake. Check the nozzles and lines for blockages or damage before replacing the pump.
Are there any recalls for the FX45 washer pump?
No. Searches of the National Highway Traffic Safety Administration (NHTSA) database show no recalls or safety campaigns related to the windshield washer pump for the 2003-2008 INFINITI FX45.
