My wiper motor isn't working, and I have been trying to remove the wiper arms to access the motor, with no luck at all. I removed the retaining nuts, and figured the arms would pull right off. Yeah, right. I sprayed WD40 on the studs, twisted, turned, pulled and every thing else I could do to the arms and they won't budge. I even bought a puller, but it won't fit. Anyone have a secret they can share with me to help before I have a nervous breakdown?
