Hello fellow bretheren I'm asking how to change bulbs in our 02-05 is300 5spd snow/trac off buttons. Mine doesn't light up @ night but, the button works perfectly. Let me know how it's done or if it's possible. I removed the whole switch & found a screw underneath but, it only turns a quarter turn & does not turn anymore. I've enclosed some pics to reference what I'm talking about. Hard for me to turn trac off @ night because I can't see it & I usually end up hitting the snow mode button. Help a fellow is member out. Thanks!
