Chevrolet Impala Windshield Washer Pump Guide (2007-2020)
If your Impala's washers are dead, the fix is likely simple and affordable.
- First, check the 'WSW' fuse in the under-hood fuse box before buying any parts.
- Crucially, verify if you have a 2014-2016 'Impala Limited' (old style) or a standard Impala (new style) to ensure you order the correct pump.
- Replacement is a simple DIY task that requires removing part of the passenger-side wheel well liner for access.
- A quality aftermarket pump like Trico is a cost-effective and reliable alternative to the more expensive OEM part.
Is Your Impala Washer Pump Failing?
A failing windshield washer pump on a 2007-2020 Chevrolet Impala usually shows clear signs. The most common symptom is a complete lack of washer fluid spraying on the windshield when you activate the switch. Before assuming the pump is bad, check two things first: make sure the washer fluid reservoir is full and check the fuse. If the fuse is good and the tank is full, listen for the hum of the pump motor when you pull the washer lever. If you hear nothing, the pump has likely failed. If you hear the pump but see little or no fluid, the lines could be clogged or the pump itself may be too weak to create enough pressure.
Critical: Which Impala Do You Own? (2014-2016)
Chevrolet created a common point of confusion for parts from 2014 to 2016. During these years, they sold both the new 10th generation Impala AND the older 9th generation body style, rebranding the old one as the 'Impala Limited'. These two different models use different windshield washer pumps. Before ordering, you must confirm if you have a 2014-2016 'Impala Limited' (old body style) or a 2014-2020 Impala (new body style).
Choosing the Right Aftermarket Pump
For a part like the windshield washer pump, an aftermarket replacement is a reliable and cost-effective choice. The original equipment (OEM) pump does not offer a significant performance advantage for this component, and an aftermarket part can provide the same function for a lower price.
Brands like Trico specialize in wiper and washer system components. Their pumps are designed to be direct-fit replacements, meaning they install without any need for modification. Reviews for Trico pumps are generally positive, with users noting they fit and work like the original part. Given the straightforward nature of this part, a quality aftermarket brand is a smart choice for your Impala.
Check the Fuse First!
Especially on 2007-2013 models, a blown washer pump fuse is common. Some early models used a 10-amp fuse that was prone to blowing. A known fix, supported by a technical service bulletin (TSB), was to replace the 10-amp fuse with a 15-amp fuse. Always check the WSW (Windshield Washer) fuse in the under-hood fuse box before replacing the pump.

Frequently Asked Questions
Is replacing the washer pump a DIY job?
Yes, this is a great job for a beginner. Access is gained by turning the front passenger wheel and removing a few clips from the plastic wheel well liner. The pump pulls straight out of the washer reservoir. The entire job can usually be done in under an hour with basic hand tools.

If you can hear the pump motor running, the problem lies elsewhere. Check for clogged washer nozzles on the hood, which can be cleared with a small pin. Also, inspect the rubber hoses for cracks, breaks, or disconnections between the pump and the nozzles. 🎬 Watch this quick fix if your pump runs but won't spray. In cold climates, the fluid inside the lines can freeze.
Are the front and rear washer pumps the same?
The Chevrolet Impala is a sedan and is not equipped with a rear window washer system. The pumps sold for this vehicle are for the front windshield only.
Do I need to drain the reservoir to change the pump?
When you pull the old pump out of the reservoir grommet, all the fluid will drain out. It's best to have a bucket ready to catch the old fluid. Alternatively, you can try to work very quickly to swap the pumps to minimize fluid loss, but it's often easier to just plan on replacing the fluid.
