So the son is trying to hook up the defroster on the rear window of the 80 Volare today... The window was replaced at some point.....as evidenced by the broken glass in the car under seats etc when we had the carpet out, and the two tabs with broken glass stuck to them in the ashtray. Thing is, the defroster has me baffled. The son was gonna go buy a repair kit from the auto parts joint.....but I figured we should see if there is continuity across the grid before spending his hard earned moolah. And its when we try to check continuity that has us wondering... Should there be a metallic coating down each side? When he probes each side with an ohmeter, he gets continuity from side to side but ONLY when the probes are on what appears to be some coating. When the probes are on the clear part, no continuity.....but the "wires" seem to be made of the same clear stuff. We arent sure if all the wires are seeing continuity or if its just one or two and the rest would be dead..... If there IS supposed to be metallic coatings on the sides and all, then someone has scraped it off ...but why would someone do that? To a new window? That makes no sense.... so in the picture below, the passenger side, you can see how thje whole side is clear EXCEPT a patch at the top..this is where we can get continuity. Anywhere else, no.
