Hi, let me first start by saying that i've searched for this alot. Ok I have headlights, brights and turnsignals but no dash lights. i've checked all the fuses, replaced the dimmer switch and used a selfpowered testlight to check the grounds on the pigtails for the gauge cluster. i hope someone can help me here. thanks.

 

I have the same problem with my '90 GTA. Radio light works but goes out too when you turn the lights on.

I can't seem to figure it out.
