Questions and answers
I have a new windshield wiper motor of just as few months. Now there is no pressure to eject the water to the windshield. I hear the motor working and a small amount of water is leaking out onto my hood on the backside of the water sprayers on the hood. I think it could be dirt-- Yes I have used needles to poke the holes to open it up. I think it might be clogged where the hose connects to the jets. How do I remove the hose to the jets== was afraid of breaking it IF I just pulled it off. Is there a connection issue that I need to know to disconnect it?
