Nissan Murano Windshield Washer Pump Replacement Guide (2003-2014)
If your Murano's windshield washers are weak or not spraying at all, this guide is for you.
- A silent pump usually means it has failed, while a humming pump with no spray points to a clog or leak.
- Aftermarket pumps are a cost-effective and reliable alternative to expensive OEM parts for this specific repair.
- The most common leak source is the rubber grommet sealing the pump, not a cracked reservoir.
- Replacement is a simple DIY job that can be done in under an hour with basic tools.
Is Your Murano's Washer Pump Failing?
A failing washer pump on a 2003-2014 Nissan Murano is a common issue, but the symptoms can sometimes point to other problems. Before you replace the pump, it's important to know what to look for. A complete failure is easy to spot, but sometimes the signs are more subtle.
Diagnose First, Replace Second
Before buying a new pump, perform these simple checks:
🎬 Watch this guide on how to diagnose your washer system.- Check Fluid Level: It may seem obvious, but an empty reservoir is a common reason for a non-working system.
- Listen for the Pump: Have a helper activate the washers while you listen near the front passenger-side wheel well. If you hear a humming sound, the pump is getting power and the problem is likely a clog or a leak. If you hear nothing, the pump motor has likely failed or there's an electrical issue like a blown fuse.
- Check for Clogs: If the pump runs but fluid doesn't spray, the nozzles on the hood or the lines themselves could be clogged. Try cleaning the nozzle openings with a small pin. In one documented case, a rodent had gotten into the reservoir and clogged the pump inlet. 🎬 See how a clogged pump inlet can affect your Murano.
- Inspect for Leaks: Look for puddles of blue or purple fluid under the front passenger side of your Murano. Leaks often come from old, brittle rubber grommets that seal the pump in the reservoir, not from the tank itself.
Choosing an Aftermarket Washer Pump
For a part like a washer pump, an aftermarket replacement is a smart and cost-effective choice. The original equipment (OEM) pump from Nissan offers guaranteed fit, but aftermarket brands like Replacement, ACI, and Trico are designed to meet or exceed original specifications for a fraction of the price. These pumps are engineered as direct-fit, OE-style replacements, meaning they will install without any modifications and use the same electrical connector. Given the simplicity of the part and the significant cost savings, a quality aftermarket pump provides excellent value for most Murano owners.
Installation Overview
Replacing the washer pump on a 2003-2014 Murano is a straightforward job that most DIYers can handle in about 30-60 minutes.
🎬 Watch this step-by-step walkthrough of the pump replacement process.- Access the Pump: The washer reservoir and pump are located in the front passenger-side wheel well. You will need to jack up the vehicle, secure it with a jack stand, and peel back the plastic fender liner to gain access.
- Drain the Reservoir: Have a bucket ready to catch the remaining washer fluid.
- Remove the Old Pump: Disconnect the electrical connector and the two fluid hoses. Then, simply wiggle and pull the old pump straight out of the rubber grommet in the reservoir.
- Install the New Pump: If your new pump came with a new grommet, it's a good idea to replace the old one. Push the new pump firmly into the grommet, reconnect the hoses and electrical plug, and refill the reservoir.
Pro Tip: Before putting the fender liner and wheel back on, test the new pump. It may take 5-10 pulls of the washer switch to prime the system and get fluid spraying from the nozzles. Also, check for any leaks around the new pump grommet.

Frequently Asked Questions
My rear washer isn't working, but the front is. Is it the same pump?
Yes, on the Murano, a single pump is used for both the front and rear washers. The pump motor simply reverses polarity to send fluid to the rear. If only one direction is failing, the issue could be a clog in that specific line, a problem with the control switch, or an internal failure in the pump.
Are there any recalls for the washer pump on the 2003-2014 Murano?
No, there are no specific recalls or technical service bulletins (TSBs) from Nissan or the NHTSA for the windshield washer pump on this generation of the Murano. Failures are typically due to normal wear and tear.
Can I just replace the rubber grommet if it's leaking?
Yes. The rubber grommets that seal the pump and level sensor are a common failure point and can often be purchased separately. However, many new aftermarket pumps include a new grommet, and given the low cost, it's often wise to replace the pump and grommet at the same time.
Do I need special tools to replace the washer pump?
No special tools are required. Basic hand tools like a jack, jack stands, a lug wrench, and possibly a small screwdriver or clip removal tool for the fender liner clips are all you should need.
