Ok, here is what happened. Basically I was putting the wiper arms back on after refitting the scuttle panel. As I was tightening the nut in for the driver wiper arm, I did it too much, not realising and *crack* Now around that area on the arm where it connects to the motor, there is a crack line around the other side and just stops around the inside. I plan on ordering a new one but, will the arm go on me soon or will it be ok for a while? Also does anyone know how much a arm would cost and can I just get one or, do I need to get a set?
