Hello Mate... Have purchased new creta 2020 SX(o) diesel AT and it has nearly been week. Even i have the same problem. The power window buttons on all doors are not illuminated. No backlight at night except 1 key (just one key not full panel) that's driver's power window key. Rest are without any illumination. That's really irritating coz after purchasing a SUV that nearly costs 19.5L you don't get this feature. If you have found any solution to this pls provide it. Found one temporary solution for this and bought illuminated sticker from aliexpress. Waiting for delivery to check its durability.
