I have a rondave and the windshield wipers are only wiping half way how do I fix it
It could be the wiper motor. Now if it comes back down and hits the car, it could be the wiper arm. If you had the arm replaced or taken off for some reason it could not be set right. If you done none of that it's most likely the wiper motor going out. Both are easy to do, just look it up on YouTube under your car.
