I have a 2010 Touring. The backlight that comes on to illuminate the radio/temp controls when you turn the headlights on is out is out on the passenger's heated seat button only. Is this a fuse issue or a simple fix? It's not a terribly big deal and I'm probably the only one that notices it, but it still bugs me nonetheless. Any knowledge how I can fix it and if it's fairly inexpensive? Thanks!
