Where is the windshield fluid pump on 2007 Impala?

The windshield washer fluid pump on a 2007 Chevrolet Impala is located in the reservoir tank itself. The reservoir is typically found under the hood, usually on the passenger side (right side). You'll see a plastic tank with a cap; the pump is integrated within that tank and isn't a separate easily accessible component. You likely won't be able to see it without removing the tank.
