I have recently acquired a 997 (my first Porsche) and discovered that only 6 elements of the heated rear window are working. My discovery came a few days after a tracker had been installed but suspect the two are not related. Just unlucky coincidence! Does anyone else have any experience of a similar issue? I suspect it may need a screen change to fix. I have peered at the elements and many have small sections of discolouration which could be breaks?
