Automatic Astra G 1.8

Good friends, the problem I have is the next my astra, I bought it 4 months ago and the fault that I could not solve is as follows: With the car on if the lights are on you already see the floor the brake pedal the car does not go out that is to say with the lights on and the brake treaded I can remove the suiche and take out the key and the car is still on the brake then release the brake, it also goes out that with the car off the car. They activate all the dashboard lights as if the suiche passes also notice that when I turn the lights alone the change lever was bone when the car is turned on and one wants to place RN or D must step on the brake to unlock the insurance but only when it turns on the lights this or unprep. Indicators move and the lights come on but the car does not go out, sincerely would gather their collaboration if someone has passed something similar or can indicate where to start since I check all the wiring of the car and it is not really worked is totally original the only thing that has more are 2 relays for the lights a thousand thanks for their help
