climate control

[svxy]

Is there something wrong with my climate control. As I adjust the temperature up or down the direction of the air changes as it should...higher temp at your feet, lower temp at your face. But my car must think its always 70 degrees inside no matter what the temp. is. When I set it at 70 degrees it almost stops blowing which makes me think, the car thinks its at that temp. Now it was 31 degrees outside today, I set the temp at 70 and it stopped blowing, then I set it at 68 and it started blowing at my face at the outside temp. just like I had turned on the vent. It didn't blow at 68 degrees it blew at 31 degrees. Shouldn't it blow out air at the the temp set or at least warmer or cooler air to get the car at the desired temperature.
