Well, I have to say that I don't know if you really can get at that indicator bulb from under the dash. I've just pulled the dash module and replaced the bulbs that way. It's pretty easy. The trim panel just pulls off (make sure you keep track of the metal clips) then a couple of 7mm bolts and the module comes out far enough to access the bulbs. While I was in there I just replaced them all so I don't have to go back.
