My daughter has a 99 SC1 and the right wiper moves but don't seem to be on the splines or something, it can be moved when the wipers are not on, or if snow on it the one goes but not the other. Can and how do you remove the wiper from the spline type drive? Or can I tighten it some how? She also just got the right front hit and behind the wheel and door panel and mirror all need to be repaired. Any advice as to best way to repair on a limited budget. Thank you.
