Just purchased a 01 V70 X/C and ironing out a couple nit-pick bugs. The HVAC system works flawlessly and all the little LED indicator lamps behind all the switches work perfectly as well, but there is no back-lighting on any of the controls. I am only assuming there should be. I could accept one or two bulbs out and rationalize that the bulbs need replacement, but since there is no back-lighting at all I'm thinking there's another issue. Anyone have any ideas?
