I have an Astra W reg, well i got stopped by the police few nights back because my brake lights were stuck on. Luckily they didnt book me but the officer said i needed to get it to a garage asap. So when i did they disconnected the brake switch behind the brake pedal and the problem remained, though the brake lights did go dimmer and brighter while they were doing this. They suggested that there was a live wire somewhere and said it was unsafe to drive. I have since discovered that if you put the lights on without the key in the ignition then you are able to open and close the windows. Any ideas anyone and how easy will it be to resolve this?
