Default 2002 Rear Window defogger not working

I tested all the fuses and the rear window defogger switch and everything is okay (according to the service manual)on my 2002. I find that I am getting current to the rear view mirrors (they are warm ) but current is not going back to the white / black wire to feed the rear window defogger grid. Where would I look next? is it a problem with the mirrors? the wiring schematic denotes a black and white feed to the rear view mirror however I can't find one when I open up the wiring feed at the door.

I would try to trace the wiring from the mirrors back. Does the rear glass heat up at all? Just a tiny bit? Very slowly? Nothing at all? Does the grid appear to be damaged at all? Sadly, fixing the wiring may involve tearing apart the trunk lid lining and or the headliner. Good luck!!

Default Re: 2002 Rear Window defogger not working - UPDATE

Yes, had to test the wires to the rear grid for current. Not hard to pull panels off.
Result - the black ground wire as well as the black/white wire were broken. They were in the black boot that protects the wires when you open the rear hatch. Apparently afer many repeated open and closes they just broke.
Oh, it's a 2002 with 265,000 miles. And yes I do use that rear deck door a lot.
