Gina, That happened to my 2002 LeSabre also, after I got it back from the mechanic for another problem. It went away by itself after a while, but now I have intermittent blowing of the motor. The air blows cold, but the fan only blows occasionally. I'm getting that checked out soon with mechanic. Sorry, but I don't really know what caused the howling sound, but I know what you mean. I didn't notice it louder with the car hotter, just with the fan on high.

I would get the AC unit checked.
