My brake lights were off when I left my friends house in his car...well when we got back the brake lights were on and nobody touched the car. We had no idea why it did this so we tried to reset the ecu...nothing, tried unplugging the battery...nothing, tried jiggling the pedal and driving and smashing the brake...nothing. The brake fluid is filled and I didn't see any leak from the brakes anywhere. Anyone know why this is?
