Easy change indeed- This is a very common problem. All the buttons on the ECC will do this eventually. 1995 buttons have the same writing, but they are made of solid plastic verses the vinyl coating that they originally came with on the 88-93 versions. 1996 and up- the auto button looks different. Easy change too I can send you a pic of mine.
The only button that I didn't change was the EXT temp button- My buttons came from the 98 SLE that my interior came from. The auto button is different, not a big deal though.
