Default Brake lights on when head lights on

I have a 1999 chevy express conversion van and when i turn the head lights on the brake lights come on to, pulled the brake light switch and they still come on. Any ideas why? Thank You
Update now i have no brake lights when headlights are on, any ideas? Brake lights work when headlights are off.

Check all the wiring and sockets for the brake lights. There is a short somewhere.
