Thanks for the info. I looked at the wires and they appear to only go from top to bottom in about the middle 3/4's of the window. They didn't seem to go around to the sides. The bottom of the window is milky and since we don't have a lot of frost here in S. Texas I am not sure that the defrost even works. I guess I will have to ease the seal away from the glass on the inside and see if I can find the wire. Does that side panel just pop off like the door panels?
