lately the rear defog. in the car has been acting up. you turn it on, and through its entire cycle (from pushing the button, to its auto cancel) it only manages to lightly clear tiny lines about two feet wide, and about 7 lines high in the center of the window. what could be causing this? is it a faulty defog. strip? do we need a whole new back window? any tips on getting this working again?? its quite annoying not having it working. and i thought it was bad having one line not work in my Legend LOL
