So like, everything works fine, when the keys aren't in, I can activate the light switch, open and close the door, and everything works... But when I start the car, the lights turns on and the switch stop working (The dash still work).. Any clues?
In short, when the car is off, the light switch works... When the car is on, the lights are on too, no matter what the light position is in. (Speaking of interior lights, like footwell, etc)
