This may have zero value but it now pops back up in my memory from delivery. When we were searching for the Ambient, I asked the salesman if the window buttons and headlight switch were illuminated. He said "no". Of course I was surprised as I cannot remember the last vehicle I had without illuminated switches. Of course, that turned out to be incorrect. I have no idea why yours aren't but I'd guess its probably just a bad fuse. Finding it might not be so easy (with three fuse boxes!). Let us know what happens.
