Is Your M45's Windshield Washer Pump Failing?
A failed windshield washer pump is a common issue on many vehicles as they age. The signs are usually obvious, but it's important to make sure the pump is really the problem before you buy a new one. The most common failure is the electric motor inside the pump simply wearing out.
Symptoms of a Bad Washer Pump
- No Sound, No Spray: You pull the washer lever and hear nothing. If there's no humming sound from the front of the car, the pump motor is likely dead or not getting power.
- Humming, But No Spray: If you can hear the pump motor running but no fluid comes out, the problem might be something else. This could be caused by clogged nozzles, cracked or disconnected hoses, or no fluid in the reservoir.
- Weak Spray: If the fluid barely reaches the windshield, the pump's motor might be getting weak and losing its ability to create enough pressure. It could also be a sign of a clog in the system.
Check the Simple Things First
Before replacing the pump, check these items: 🎬 See how to diagnose a failing washer pump motor. Make sure your washer fluid reservoir is full. Check the fuse for the washer system. Also, check the spray nozzles on the hood to see if they are clogged with wax or debris. You can often clear them with a small pin.

When replacing the washer pump on your M45, you have two main choices: a new aftermarket part or a more expensive Original Equipment (OEM) part from an Infiniti dealer. For a simple part like a washer pump, an aftermarket version offers the best value with reliable quality.
Trico is a well-known brand that has been making wiper and washer system parts since 1917. Their pumps are designed to be a direct fit, making installation easy without needing any special adjustments. For the INFINITI M45, a Trico aftermarket pump is a cost-effective and dependable choice that performs like the original.

DIY Installation Tip
The washer pump is located on the washer fluid reservoir. On the 2003-2010 M45, this is typically accessed by removing some of the plastic fender liner inside the front passenger-side wheel well. You may not need to remove the entire wheel. Once you can see the reservoir, the pump unplugs and pulls out of its grommet. The new one pushes right in.

Are there any recalls for the M45 washer pump?
No, there are no specific recalls or Technical Service Bulletins (TSBs) from INFINITI or the NHTSA for windshield washer pump failure on the 2003-2010 M45. Recalls found for this vehicle relate to the Takata airbag system.
How long does it take to replace a washer pump?
For a mechanic, this is a quick job, usually taking less than an hour. If you are doing it yourself for the first time, plan for about one hour to be safe.
Do I need to drain the washer fluid to replace the pump?
Yes, you should drain the reservoir before removing the old pump. The pump is usually at the bottom of the tank, and fluid will spill out when you pull it. You can drain it by running the pump if it works at all, or by siphoning the fluid out. Have a bucket ready to catch any remaining fluid.
Could my problem be the washer fluid level sensor?
A bad level sensor will cause a warning light on your dash but will not stop the pump from working. If your pump isn't spraying, the level sensor is not the cause of that specific problem.
