Replacement radio parts for a 2002
On a 2002 Grand Cherokee Limited I'm trying to replace the radio knobs that control the Fade (F/R) and Balance (R/L). Any suggestions about the best way to do this? They don't appear to be a very popular replacement part, so not easily accessible via parts sites. Admittedly, I'm totally naive about how to source parts like this - dealer, junk yard, online, etc, when I don't really know the actual part name or the potential years this radio (and hence the knobs) may be installed upon. Thanks!!!
