GM GENUINE PARTS windshield washer pump 84518407 — direct-fit OEM replacement, reliable fluid flow

The GM Genuine Parts 84518407 camera washer fluid pump is the original-equipment replacement that delivers consistent washer fluid flow to clean your windshield when you need it.

If your washer system is weak, sputtering, or not delivering fluid at all, replacing the pump with a GM-specified unit restores proper operation and helps maintain visibility in wet or dirty driving conditions. This pump is made to the same fit, dimensions, and performance standards as the factory-installed component, making it a straightforward swap for compatible GM vehicles.

How will this pump restore my washer system performance?

Installed in the washer fluid reservoir, the pump pressurizes and pushes fluid through the lines to the spray nozzles so the windshield receives an even stream. A fresh pump eliminates common failure points such as weak flow, intermittent operation, or complete loss of spray.

• Replaces worn or failed factory pump for reliable fluid delivery
• Restores steady spray patterns to clear dirt and road film
• Designed for correct electrical and hose connections on GM models

What makes this an OEM GM Genuine Parts option?

GM Genuine Parts are produced to match the original part’s specifications for fit, function, and durability. Choosing an OE-coded pump reduces the risk of fitment issues and ensures compatibility with factory wiring, seals, and mounting points.

• Manufactured to GM original-equipment specifications
• Quality controls aimed at consistent flow rate and longevity
• Direct-fit design simplifies installation without modification

Is installation difficult and what should I check during replacement?

Installation is generally straightforward for DIYers who are comfortable working near the washer reservoir. Before installing, inspect hoses and connectors for damage and confirm electrical terminals are clean and secure to avoid repeat issues.

• Disconnect battery or vehicle power before handling electrical connectors
• Verify reservoir fittings and hose clamps are intact and leak-free
• Prime the pump by filling the reservoir and testing spray after mounting

Which symptoms indicate this pump needs replacement?

Common signs include no fluid output when activated, erratic spraying, or weak streams that don’t reach the windshield. If fuses and switches check out but the problem persists, the pump is a likely cause.

• No fluid from washer nozzles despite switch activation
• Intermittent operation or reduced spray pressure
• Audible motor noise without fluid delivery
