    Dashboard backlight goes out when Headlights are switched on.

    Hi everyone. I'm new to this Forum as I've just bought an 03 Astra Estate 1.7tdi.

    When the headlights are off, the speedo, radio display, milometer etc are lit up. But when I switch the headlights on these back lights go out making the display very difficult to read. my girlfriend's Corsa does the same thing.

    Is this normal, or is it a common fault with Vauxhalls? If so how do I fix it?

    Thanks in advance.

    Sounds like the dimmer switch on the right hand side of your like switch it's a little spin wheel their is two of them one does your headlight beam level and the other dims you interior lights. Rotate it all the way up, their is a mark next to the wheel that shows the band getting bigger the bigger it get the more light you will have in the dash, so all the way up and it will be at full intensity
