This just started in December..windshield fluid won't spray, I don't even hear the motor. Didn't realize a problem, just thought I needed fluid. Kept telling my boyfriend wiper fluid was empty. I just thought he didn't fill it when I asked, until he told either was using too much wiper fluid...Anyway..my Mom used my car & said it hadn't been filled, but she didn't hear the motor...do now? Anyone have this problem? Thanks!
