I don't know about the other lights but the two that light the heater controls are a right pain. Mine kept not coming on every so often. After a few weeks of bashing the centre console my brother said "why don't you just fix it!" Like an idiot, I decided to do this on a Thursday night, thought it'd be a quick job. Mine doesn't have climate control by the way, so I'm sure it'd be easier with climate because... The heater controls are in a separate "box" behind the silver centre console cover. When you take this apart, the heater controls come loose, so you need to remember what settings you had them on. Also the fan speed one spins freely from the temp one. Then the air-con and heated screen buttons will fall out, then the little orange indicator lights will fall out cos they're a light tube which sits just over the circuit board. Sorry for the long post but I thought it'd be worth tellin you lot it'll take more than 5 mins with plenty of "oh s**t's" when bits start falling out. I only replaced mine with standard bulbs tho. They're tiny cap-less ones but can't remember what number they are.
