i found that the defrost light button, hazard light button, and 2 buttons on the digital climate control don't light up anymore when i turn the headlight on. i search in this forums and found that they could change the LED bulb inside the button. i know how to remove the hazard light button, but i don't know how to remove the defrost light button. do you guys have any i dea? also.. does anyone know how to remove the defrost button? do i have to remove the upper cover on the steering wheel? how to disassemble the climate control unit so that i can replace the light bulb?

any advice will be great..
