While cleaning out the vehicle this weekend I noticed there was something that for spilled, very small drop, on the 4wd low button. When I went to rub it off with my Mopar interior cleaner the letters started to run off so I stopped. Feeling it with my finger it didn't feel smooth like the other buttons near it and all of would rub off easily if I tried. I'm guessing this wouldn't be covered under warranty. Is it possible to replace that button?
