The heated windshield never worked on my VNL, I've had it a year. The windshield cracked and just got replaced, I hoped it would fix it, but no. The switch on the dash lights up, the fuse is good, there must be something else in there. I replaced the lock module when I got it, I'm hoping one of the other modules in that area is for the windshield, does anyone know?
Or is this function controlled by the body control module?
