I have read a number of posts dealing with lamp replacement for the Climate Control buttons for the 95 S500. None of them describe how to replace the lamp for the temp. adjust thumb wheel specifically. I have removed the Auto button cover and there is one bulb under it which lights it, but not the thumb wheel. That lamp works and the auto button is illuminated but not the thumb wheel. I could not see any other lamps. I also have an alldata subscription and cannot find the solution there either. So, I need some help, please! Thanks!
