Dash lights not working?

I just recently (2 days ago) Installed a pioneer stereo in my Hyundai. Upon reconnecting the battery to check and see if the stereo worked, it did but the dash lights and lights where the shifter and a/c are do not come on when I turn the lights on. The exterior lights all work fine as well as my overhead lights (the ones you push to come on). I have checked behind the dash to make sure I plugged everything back in and it all seems to check out. Any suggestions?
