So I just got a 2003 tiburon gt v6, and the lights on the radio didn't work and only one of the lights on the climate controls worked, then I smacked it and half of them light up and the radio lights came on, I already took the panel off and unplugged and checked the connectors no issues. It's only on the console, the gauge lights all work fine. Any ideas?

 

Sounds like the headunit itself is bad.
