OK easy fixed, jack up your car and find the Air-conditioning drain pipe, get a piece of coat hanger and shove it up the pipe to loosen and crap in there. Once the Air-conditioning has been on, it will cause water buildup which is supposed to drain off, if the drain pipe is blocked the water will build up and cause steam when it gets to the heater core. I had the same problem with a Commodore I had some years ago.
