INFINITI G20 Windshield Washer Pump Guide: 1991-2002
Having trouble cleaning your windshield? Your G20's washer pump may have failed.
- Failure is common due to age; it is not a sign of a major vehicle problem.
- An aftermarket pump from a brand like Trico is a reliable and much more affordable option than OEM.
- Verify your G20's model year (P10 vs. P11) to order the correct pump, as they are different.
- This is a simple DIY repair that can be completed in under an hour with basic tools.
Is Your G20's Windshield Washer Pump Failing?
A non-working windshield washer is a common issue on older cars like the 1991-2002 INFINITI G20. The pump motor simply wears out over time. Before you assume the pump is bad, check two simple things first: make sure your washer fluid reservoir is full and check the fuse for the washer system. 🎬 Watch: How to diagnose and troubleshoot your washer system. If both are good, the pump is the most likely cause of the problem.
Key Symptoms of a Bad Washer Pump
- No Sound, No Spray: You push the washer button and hear nothing. The pump motor is likely dead or not receiving power.
- Pump Hums, But No Fluid Sprays: If you can hear the pump motor humming but nothing comes out, the pump's internal impeller might be broken, or the filter could be clogged.
- Weak or Uneven Spray: If the fluid barely reaches the windshield or sprays unevenly, the pump may be getting weak and failing to create enough pressure. This can also be caused by clogged nozzles.
Known Issues & Recalls
As of early 2026, there are no specific recalls or Technical Service Bulletins (TSBs) from INFINITI or the NHTSA for the windshield washer pump on the 1991-2002 G20. Failures are typically due to the age and normal wear of the part rather than a specific design defect.
Choosing a New Aftermarket Pump for Your G20
For a vehicle like the G20, an aftermarket washer pump is a smart and cost-effective choice. The original OEM pumps are expensive and offer no significant advantage for this simple part.
- OEM (Original Equipment Manufacturer): This is the part your car came with from the factory. It will fit perfectly but is the most expensive option.
- Aftermarket (Trico and others): Aftermarket brands like Trico produce replacement parts that meet or exceed original specifications. For a simple motor like a washer pump, a quality aftermarket part provides the same function and reliability as OEM for a fraction of the price. Trico is a well-known brand in wiper systems.
Generation-Specific Parts
The INFINITI G20 has two generations, and they use different washer pumps. Ordering the correct one is critical for proper fitment.
- 1991-1996 (P10): Uses OEM part number 28920-17V00.
- 1999-2002 (P11): Uses OEM part number 28920-1E400.
Always confirm the part fits your specific model year before purchasing.

Frequently Asked Questions
Where is the washer pump located on the INFINITI G20?
The windshield washer pump is located at the bottom of the washer fluid reservoir. On the G20, you will typically need to access it by removing the front passenger-side wheel and pulling back the plastic fender liner to see the reservoir and pump.
How do I know if the pump or the switch is bad?
Listen carefully when you activate the washer. If you hear a low humming sound coming from the front of the car, your switch is working and sending power to the pump. If you hear nothing at all, the problem could be the switch, a fuse, or the pump motor itself.
Is this a difficult DIY repair?
No, this is a great job for a beginner. The replacement is straightforward and requires basic hand tools. 🎬 See this step-by-step guide on replacing the washer pump. The hardest part is often just accessing the pump behind the fender liner. The pump itself usually just pulls out of a rubber grommet on the reservoir. 🎬 Watch: A helpful walkthrough of the Nissan washer pump replacement. The job should take less than an hour.
Do I need to drain the washer fluid to replace the pump?
Yes. When you pull the old pump out of the reservoir, all the fluid will drain out. It's best to either drain the tank into a clean container beforehand or be prepared for it to spill when you remove the pump.
