2007 radio/climate control lights
 

Hey folks, new here, but I bought a 2007 DX for my son to commute to school and back. I drove it the other night and noticed that 1/2 the lights for the climate control and radio weren't on. We also discovered that the radio display flashes once when the turn signal is activated. I've done some reading and discovered this lights are a common problem, however I have not yet found someone posting a solution.

It seems to me this maybe a ground issue, and I figure that's a good place to start. Does anyone know where the grounds for the dash are?

Thanks in advance for any insight you can provide.
