I purchased this car in October 2009. Great car so far. Recently I noticed my windshield washer fluid wasnt coming out when I tried to use it. Assuming it was out I bought some new washer fluid at wal-mart and opened up the hood. Sure enough it looked empty. I filled it up but was amazed at how little it took to fill it up....??? Then I got in the car and while driving tried the washer fluid....nothing. I am wondering if the 2007 Impala has a history of washer fluid pump problems
