Default air conditioning problem, it's always on!

driving the other day, i noticed cool air coming from the vents on a hot day. the selector on the dash wasn't set to a/c, but that didn't matter. all settings had cool air coming from the vents, definitely cold a/c.

it seems that the a/c compressor is running all the time. i did a search and really couldn't find anything related to that.

any tips?

What a chilling discovery... Ok, bad jokes aside (I apologize for that) I really wouldn't have a clue unless the wires going to the compressor clutch have somehow shorted together... That'd be about my best guess
