Could be a bad relay getting stuck in the ON position..
I believe the relay for those are behind the dash where the vents are on the center of the dash.. I could be totally wrong about the location though. I remember reading that along time ago.

I know there are a set of relays on the drivers side under the dash. You need to pull the knee panel down to see those.
