Scott, the grille does pop off. Need to get a thin, wide tool (putty knife) and start it out on the side that is closest to the center of the dash. You need to be patient and careful with this task. But.., if your fader has been doused with coffee, that's the most likey culprit. Goes for between $20.00 and $28.00 depending where you get it (check the parts shop here). Remove the center wood panel and pop the fader out. Reverse to reassemble.
