Battery going dead and the heater and ac fan will run unless the heat switch is off even if the ignition switch is off and key is out of it. The ignition switch does not have any play in it.

More often than not you have water leaking in the fuse box and gem module under dash on driver side. Look at back side of it on seam. If its Grey or green coming out of it even water you need new fuse box gem and get your wind shield resealed
