Hi all, I'm in desperate need of help...My wife's 2005 Galaxy 1.9 TDi has developed an electrical fault that has got me baffled. So in a nut shell, The dash and switch background lights remain on even with the key out of the ignition and the car locked. Also we have noticed the rear number plate light is also on. I've done all the good things by checking all the earths under the bonnet and found nothing. This is an intermittent fault as it disappeared this morning after driving it for a while. It looks to me like a bad earth however whilst playing with the dash dimmer/headlight level switch I got the fault to return. the headlight level side still works but the dimmer does not. I disconnected the switch but the fault remains. Any help will be very welcome.
