I got it. It was the brake light switch. No answers need now, thanks.
Pull out on the light switch when you have turned it to the right to turn on the lights.

The light control module could be the cause of hazard lights coming on after the car is turned off. There could be a problem that has caused this module to become wet and it is now not working correctly.
