Hello All.. I was wondering if someone could help me! All of a sudden, my wipers are very slow. Sometimes they get stuck at the top, but then they may do the whole rotation, but very slowly!! Im thinking it may be the motor, but they still move! Maybe its locking up somehow?? Please help if you can, so that I don t have to pay the dealer 10 x's as much as I would if i could do it my self!! THANKS!!
