Hey, I've just noticed a strange problem with my 2003 astra g and was wondering if anyone has any ideas how to sort it.
Whenever I switch the sidelights/headlights on, all of my interior lights go out (meaning my needle backlights, radio etc.) as well as my main screen (which usually shows the radio station). This has only just happened, and can't think of anything that would've triggered it. It isn't affected when I just flash my main beam, but as soon as I put the lights on properly they all just go off.
Anyway, I'd be grateful if someone could point me in the right direction!
