The windshield washer malfunctions when turning on to use. It works at times in low and high speeds but the middle speed will work but then speed up and stop altogether. The switch has been changed. What is the next step?
I'm confused, are you talking about the windshield washer that sprays the windshield or are you talking about the windshield wiper middle speed?
I also need to know the year of the car?
The more information you can give me the better I can help you.
