Fixed vent tension cable, stereo controls stopped working

[conblurgh]

Like the title says, vent selector cable came loose. Popped the panels off, put the cable back in place, hey I can select my vents again.

Now, the stereo panel no longer lights up, and none of the controls are responding. Stereo is getting power, because it's playing a CD that's been in there for ... no idea how long. Eject button doesn't seem to be working, so I guess that CD is just playing now. Volume controls aren't working either.

So, guess I botched something?
