In most cases the bulb that lights that side is under the "AUTO" button on that side. The wood does't need to be removed at all.
You need a small pick to get under the auto button & while holding very slight pressure on the button you pull out on the pick.
Then there is a slot that needs to be un-screwed, you will then find the bulb.
