I have a 98 Pontiac Grand Prix. The fluid is not dispensing. There is plenty of fluid. The nozzles are not clogged. I changed the fuse. So I‘m thinking it‘s the pump. I searched the problem but could only find advice for several different cars, unfortunately not mine. I don‘t have a tester so I‘m taking a chance buying a new pump. I doubt they will give me a refund if that is not the problem.
